The Global Government Bond Portfolio seeks as high a level of current income and
capital appreciation as is consistent with investing principally in high-quality
bonds of the U.S. and foreign governments.

HEATH B.
MCLENDON

Chairman


Dear Shareholder:

We are witnessing unparalleled prosperity in the United States today. As a
nation, we are more affluent than ever before, with much of that wealth created
in the last several decades. We are benefiting from a world that has been
largely at peace since the official end of the Cold War in 1989. We are reaping
the fruits of the restructuring of American businesses that took place in the
70s and 80s and benefiting from growth in worldwide demand for our products.

This unparalleled U.S. prosperity is now being followed closely by Europe.
Companies there are undergoing restructuring similar to that of the U.S. of the
last two decades. More and more, the inefficiencies of state-controlled
institutions in Europe are being replaced with the expansion of a free and more
competitive marketplace. As we approach the dawn of a new millennium, these
positive developments have enabled the U.S. and most of Europe to experience the
greatest period of peace and prosperity in generations.

The rapid rise of global markets in recent years has been helped in no small
measure by sophisticated monetary policy. In the U.S., policy-making bodies,
such as the Federal Reserve Board, coupled with technology-led productivity
gains, have controlled inflation to the extent that it is not a significant
factor in the U.S. economy today. This is also becoming true in Europe, where
the move to a common currency has forced both fiscal and monetary policies to
accomplish the same objective of bringing inflation and interest rates down
significantly in countries such as Italy and Spain. And as interest rates have
come down, investment funds have flowed into stock markets, which in turn have
helped propel dramatic gains in the U.S. and European financial markets.

Now, the developing world is taking its cue from the U.S. and Europe. Perhaps
the most meaningful example is Latin America, where, after a very rocky period
in the last decade, monetary and fiscal policy reforms have stabilized its
economies and established a base for solid and sustainable future growth. For
example, Brazil, historically plagued by hyperinflation that reached as high as
2,500% per year, has brought inflation down to manageable levels and plays a
larger role on the world stage today than ever before. Even lesser developed
countries in Eastern Europe and Africa are clearly demonstrating the positive
aspects of more freedom and greater competition.

The one area that is currently not enjoying growth and prosperity are parts of
Asia, particularly Japan, Southeast Asia and South Korea, where extraordinary
economic growth and expansion during the last several decades resulted in
overheated and overly extended financial conditions that are currently in the
painful process of readjustment.

For many years, U.S. investors had little reason to look beyond their own
shores. Over time, the U.S. market has rewarded patient investors with handsome
returns. However, as the world becomes a truly global and interdependent market,
it has become more important than ever for investors to remain globally
diversified.

Despite the historic and outsized returns of the U.S. stock market in recent
years, the U.S. has yet to be the top-performing market in any one year over the
last two decades. We continue to believe that maintaining a well-diversified
portfolio with some international exposure is an essential key to investing
success.

In this report, you will find specific market commentary and performance
information for the Smith Barney World Funds, Inc.--Global Government Bond
Portfolio, International Equity Portfolio and International Balanced
Portfolio--beginning on page three.

Performance Update

For the six months ended April 30, 1998, the Smith Barney World Funds--Global
Government Bond Portfolio ("Portfolio") generated a total return of 3.84% for
Class A shares before deducting any sales charges. The Portfolio outperformed
the average total return for global income funds of 3.24% for the same period
according to Lipper Analytical Services, Inc. (Lipper is an independent
fund-tracking organization.) In comparison, the J.P. Morgan Global Bond
Index--Hedged returned 4.93% for the same period. Additional information about
the Portfolio's other share classes can be found on pages six and seven.

We are pleased to announce that your Portfolio's Class A, B and C shares were
awarded a four-star rating from Morningstar, Inc.* for the three-year period and
overall for the period ended March 31, 1998. Past performance is not a guarantee
of future results.

Investment Strategy

The Global Government Bond Portfolio seeks as high a level of current income and
capital appreciation as is consistent with its policy of investing principally
in high-quality bonds of the U.S. and foreign governments. We strive to
outperform the U.S. government bond market with no more risk than investing
solely in U.S. government bonds. In addition, we utilize a hedging strategy to
minimize the risk of currency fluctuations.

North America

During the past six months, we have continued to devote a significant portion of
the Portfolio's assets to U.S. Treasury securities. As of April 30, 1998, U.S.
Treasury securities represented approximately 29% of the Portfolio, compared to
roughly 32% as of October 31, 1997. In our view, a strong U.S. dollar and sound
underlying domestic economy have made these securities attractive investments,
especially as financial turmoil persists in overseas markets.

Interest rates have continued to decline in the U.S., reaching historic lows in
January as Asia's financial and economic crisis appeared to worsen. The central


- ----------
*    Morningstar, Inc. proprietary ratings reflect historical risk-adjusted
     performance through March 31, 1998. The ratings are subject to change every
     month. Morningstar, Inc. ratings are calculated from the Portfolio's three-
     and five-year returns (including the effects of all fees and sales charges)
     in excess of 90-day T-bill returns. Different classes within a fund share a
     common portfolio of securities. The top-performing ten percent of the funds
     in a rating category receive five stars, the next 22.5% of the funds
     receive four stars, the middle 35% receive three stars, the next 22.5%
     receive two stars and the bottom 10% receive one star. The Portfolio was
     rated among 1,403 taxable bond funds.

question now facing investors and the Federal Reserve Board ("Fed") is how much
longer the U.S. economic expansion--now in its eighth year--can continue before
igniting inflation. Evidence of emerging inflationary pressures has often been
conflicting. For example, the U.S. unemployment rate, a traditional indicator of
rising prices, has remained remarkably low, recently reaching its lowest levels
in nearly thirty years. Yet, wholesale commodity prices, especially oil prices,
have remained stable or even fallen.

Those who favor a wait-and-see approach to U.S. monetary policy have argued that
overseas recessions should offset any inflationary pressures building in the
U.S. In addition, the widely expected slowdown in U.S. economic activity did
materialize to some extent earlier this year as weakness was seen in
manufacturing, factory orders and durable goods orders. This weakness hinted
that corporate America might be beginning the process of scaling back business
investment in response to a reduction in demand from many Asian economies.

So far, Fed policy-makers have chosen to remain on the sidelines rather than
risk any premature action that could upset the balance of forces that have kept
the U.S. economy humming at near perfect pitch. Moreover, raising short-term
interest rates now could exacerbate an already precarious situation in Asia by
further fueling a flight of capital out of the region.

In recent weeks, some Fed officials have publicly voiced their concerns that,
given the relatively lofty valuations of many U.S. stocks, the U.S. could be
creating an "asset bubble" similar to that of Japan in the early 90s, just prior
to that country's collapse into a prolonged multi-year recession. Following the
March 1998 meeting of the Federal Open Market Committee, the Fed's policy-making
body, officials announced a bias toward tightening monetary policy after months
of maintaining a neutral stance. We believe that it's now becoming increasingly
possible that the Fed may be preparing for an interest rate hike later this
year.

Europe

The European bond market performed well during the reporting period as all of
the continental bond markets tended to move together, underscoring the belief
that European monetary and economic integration was a fait accompli. In the
first quarter of 1998, the difference in returns between the best performing
market, Denmark (3.32%), and the worst, Germany (2.97%) was a mere 35 basis
points. (A basis point is 1/100 of a percent.)

Since the Asian financial crisis initially erupted in the summer of 1997,
government bond yields in Japan, the United States and Germany have fallen by 74
basis points, 83 basis points and 78 basis points, respectively. In our opinion,
the relative outperformance of European bonds in the first quarter (when
ten-year German bond yields fell by 42 basis points while U.S. Treasury yields
remained static) was, in effect, a catch-up on the strength seen elsewhere in
reaction to events in the Far East.

Another major factor in the resurgence of European bond performance has been
widespread reappraisal of the prospects of the Euro, the proposed common
currency for European Union ("EU") member countries. The fundamental economic
backdrop in Europe has improved substantially. The unemployment rate in both
Germany and France fell in the early months of 1998 after having risen
inexorably for the past three years. At the same time, there was a big decline
in the rate of consumer price inflation in Germany, falling from 1.7% to 1.2% in
January, driven mostly by large drops in imported commodity prices.

During the reporting period, we sold all of our holdings in Belgium because they
were underperforming and we believed we needed to trim our core European
exposure. We also reduced our

position in Irish bonds by more than half because its strong economy and robust
financial markets unexpectedly delayed any interest rate cuts.

Japan

Japan remains mired in economic stagnation and has yet to join the financial
boom that many other developed nations have enjoyed in recent years. Investors
have increasingly looked to the Japanese government to rescue its moribund
economy. However, it is still not clear whether Japan can summon the political
will to undertake the inevitably painful, but necessary, restructuring steps
needed for Japan to effectively compete in the new global marketplace. Earlier
this year, Prime Minister Ryutaro Hashimoto announced a stimulus package to help
free up the economy but the plan failed to capture the confidence of investors.
In addition, Japan has been rocked by high profile scandals ranging from the
forced closure of Yamaichi Securities, the fourth largest brokerage firm in the
country, to the resignation of its Finance Minister, Mr. Mitsuzuka.

Nevertheless, the strength of the U.S. dollar versus the yen has enabled
U.S.-dollar-based investors to earn competitive returns despite Japan's very low
bond yields. Given Japan's financial and economic weakness, we believe that the
U.S. dollar's strength against the yen should continue. Therefore, we maintained
our exposure to Japan, which was approximately 19% as of April 30, 1998.

We thank you for your investment in the Smith Barney World Funds--Global
Government Bond Portfolio.

     contingent deferred sales charges ("CDSC") with respect to Class B and C
     shares.

(2)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A shares reflect the deduction
     of the maximum initial sales charge of 4.50%; Class B shares reflect the
     deduction of a 4.50% CDSC, which applies if shares are redeemed within one
     year from initial purchase. This CDSC declines by 0.50% the first year
     after purchase and thereafter by 1.00% per year until no CDSC is incurred.
     Class C shares reflect the deduction of a 1.00% CDSC, which applies if
     shares are redeemed within the first year of purchase.

++   For the period from January 1, 1994 to October 31, 1994, which reflects a
     change in the fiscal year-end of the Portfolio.

+    Total return is not annualized, as it may not be representative of the
     total return for the year.

*    Inception dates for Class A, B, C and Y shares are July 22, 1991, November
     18, 1994, January 4, 1993 and February 19, 1993, respectively.

     charge at the time of investment and the reinvestment of dividends and
     capital gains, if any, at net asset value through April 30, 1998. The J.P.
     Morgan Global Bond Market Index is a daily, market-capitalization weighted,
     international fixed-income index consisting of 13 countries. The index is
     unmanaged and is not subject to the same management and trading expenses as
     a mutual fund. The performance of the Portfolio's other classes may be
     greater or less than the Class A shares' performance indicated on this
     chart, depending on whether greater or lesser sales charges and fees were
     incurred by shareholders investing in the other classes.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption values may be more or less than the original cost. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

Equity Portfolio ("Portfolio") returned 15.37%. In comparison, the Morgan
Stanley Capital International ("MSCI") EAFE Index had a total return of 15.59%
for the same period. (The MSCI EAFE Index is a composite portfolio consisting of
equity total returns for the countries of Europe, Australia, New Zealand and the
countries in the Far East, weighted based on market capitalization.) Performance
information about the Portfolio's other classes of shares can be found beginning
on page eleven. As of April 30, 1998, the Portfolio owned securities of 66
issuers in 22 countries, consistent with its broadly diversified investment
approach that seeks to minimize portfolio risk.

For much of the past three years we have materially overweighted European stocks
in the Portfolio, both in large- and mid-capitalization growth stocks. It was
this emphasis on European companies that contributed most to the Portfolio's
returns during the reporting period. The strength of the U.S. dollar
considerably reduced unhedged returns in 1997, while the large-capitalization
stock market bias so evident in the U.S. also caused large-capitalization
international stocks to outperform smaller stocks. However, our emerging market
(i.e., non-EAFE) exposure penalized the Portfolio's performance somewhat during
the year as the emerging markets materially underperformed the developed
markets.

Investment Strategy

We pursue a "bottom-up" approach to stock investing-- namely, we look for
promising companies and industries rather than trying to discover investment
opportunities based on the present or future condition of the global economy,
the financial markets or the performance of particular markets. We seek
companies growing at a faster rate than their local country's economic growth
rate. At the same time, we strive to maintain a risk level no higher than that
of the overall international equity market through broad diversification in a
variety of markets.

Market and Portfolio Update

In our view, three trends predominated in the international stock markets during
the latter stages of the reporting period:

o    Large-capitalization stocks materially outperformed mid- and
     small-capitalization stocks.

o    The stock markets of relatively mature, developed economies outperformed
     the more volatile and less liquid emerging markets.

o    The strength of the U.S. dollar versus the currencies of the United States'
     major trading partners largely negated returns earned in local currencies.

The latter months of 1997 and early 1998 were marked by a sense of crisis in the
international markets. The

Southeast Asian currency collapse radiated outward, engulfing not only some of
the strongest regional economies (such as Taiwan and Singapore) but also
ultimately crushing the South Korean economy and its currency. In Japan, the
largest Asian stock market and economy and a major regional lender, the crisis
contributed to an already deteriorating outlook for that country.

We believe the Asian currency crisis and economic collapse has far-reaching and
as yet not fully understood implications for global capital markets. So far,
rescue efforts have centered on creating stability and stemming further
precipitous declines in currencies and consumer and business confidence-- such
as the feverish year-end efforts of the International Monetary Fund ("IMF") and
global banks to prevent a total collapse of the South Korean financial system.
In light of this turmoil, the strength of the U.S. dollar and bond market, to
some degree, has reflected investor preferences for liquidity, stability and
strength.

But the intermediate effects of these financial woes on Asia cannot be denied:
economic contraction and decline, massive bankruptcies and debt
restructurings/reschedulings, and potential labor and civil unrest have resulted
in an investment climate of much greater risk. Whether government and business
policy-makers have the will and flexibility to make the correct rehabilitative
choices remains unanswerable and we believe another six to twelve months of
uncertainty in Asia appears very likely.

Moreover, European and U.S. companies may not escape untouched as their exports
to Asia decline. Furthermore, competitive Asian-produced goods are likely to
flood domestic markets now that prices (in U.S. dollars) have declined
substantially. While many U.S. companies have already used the Asian economic
weakness as an explanation for earnings shortfalls from consensus expectations
in recent reporting periods, the severity of the downturn should really be felt
in 1998.

Yet, despite the number of bearish influences at work on the non-U.S. markets in
the past six months, there continue to be many positive developments, such as:

o    The push for European monetary union has created favorable macroeconomic
     conditions, the likes of which have not been seen for two decades. Interest
     rates and inflation are, and likely will remain, subdued, thus heightening
     demand for stocks from individuals and institutions. Eleven countries have
     successfully reformed their economies and qualified for the first round
     selections in the European Union.

o    Corporations in Europe are continuing to restructure, boosting investor
     returns and, for the first time, aligning management interests with
     external shareholder interests through equity incentives.

o    The strengthening of the U.S. dollar against its major trading partners of
     the past 30 months has improved export competitiveness for many major
     European and Asian exporters and led to an upturn in the consolidated
     European economy.

o    Restructuring of many industries continues (such as in financial services
     and pharmaceuticals), improving economies of scale and eliminating
     inefficient local and regional goods and service providers. At the same
     time, innovative mid-size companies are finding access to capital, and an
     open door to technologies and processes that lower costs for businesses and
     consumers.

o    Much of Latin America has recovered from the "tequila crisis" of early
     1995.

For these reasons, we remain largely positive on the prospects for international
markets, particularly European markets, in the coming months.

Thank you for your continued confidence in our investment approach.

(1)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value and does not reflect the deduction of the
     applicable sales charges with respect to Class A shares or the applicable
     contingent deferred sales charges ("CDSC") with respect to Class B and C
     shares.

(2)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A shares reflect the deduction
     of the maximum initial sales charge of 5.00%. Class B shares reflect the
     deduction of a 5.00% CDSC, which applies if shares are redeemed within one
     year from initial purchase. Thereafter this CDSC declines by 1.00% per year
     until no CDSC is incurred. Class C shares reflect the deduction of a 1.00%
     CDSC, which applies if shares are redeemed within the first year of
     purchase.

++   For the period from January 1, 1994 to October 31, 1994, which reflects a
     change in the fiscal year end of the Portfolio.

+    Total return is not annualized, as it may not be representative of the
     total return for the year.

*    Inception dates for Class A, B, C, Y and Z shares are February 18, 1986,
     November 7, 1994, January 4, 1993, June 16, 1994 and November 7, 1994,
     respectively. Class A share performance includes the return on the Fenimore
     International Fund whose management was assumed by Smith Barney on November
     22, 1991.

+    Hypothetical illustration of $10,000 invested in Class A shares on April
     30, 1988, assuming deduction of the maximum 4.50% sales charge at the time
     of investment and the reinvestment of dividends and capital gains, if any,
     at net asset value through April 30, 1998. The Morgan Stanley Capital
     International ("MSCI") EAFE-GDP Weighted Index and the MSCI EAFE Index are
     composite portfolios consisting of equity total returns for the countries
     of Europe, Australia, New Zealand and countries in the Far East. The MSCI
     EAFE-GDP Weighted Index is weighted based on each country's Gross Domestic
     Product and the MSCI EAFE Index is weighted based on each company's market
     capitalization. The Indexes are unmanaged and are not subject to the same
     management and trading expenses as a mutual fund. The performance of the
     Portfolio's other classes may be greater or less than the Class A shares'
     performance indicated on this chart, depending on whether greater or lesser
     sales charges and fees were incurred by shareholders investing in the other
     classes.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption value may be more or less than the original cost. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

++   It is the opinion of management that the MSCI EAFE Index is a more
     appropriate broad-based benchmark for the market in which the Portfolio
     invests than the MSCI EAFE-GDP Weighted Index. In future reporting, the
     MSCI EAFE Index will be used as a basis of comparison of total return
     performance rather than the MSCI EAFE-GDP Weighted Index.

Performance Update and Investment Strategy

The Smith Barney World Funds -- International Balanced Portfolio ("Portfolio")
seeks a competitive total return on its assets from growth of capital and
current income through a balanced investment in the stocks and bonds of non-U.S.
issuers. The Portfolio gives investors the opportunity to participate in
potential profits worldwide and to diversify assets over a number of countries'
equity and fixed-income markets. For the six months ended April 30, 1998, the
International Balanced Portfolio returned 3.98% on Class A shares before the
deduction of any sales charges. In comparison, the MSCI EAFE Index returned
15.59% and the J.P. Morgan Global Bond Index (hedged) returned 4.93% for the
same period. Additional performance information about the Portfolio's other
share classes can be found on page sixteen. As of April 30, 1998, stocks
represented nearly 69% of the Portfolio's holdings, bonds made up roughly 25%
and the remaining 6% consisted of cash equivalents.

Please note that the International Balanced Portfolio utilizes a team management
approach with the stock portion managed by Jeff Russell and James Conheady
(International Equity Portfolio) and the bond portion managed by Victor Filatov
and Denis Mangan (Global Government Bond Portfolio). For a more in-depth
discussion of economic and market events during the reporting period, please
refer to the Manager's Commentaries for the International Equity Portfolio that
appears on page nine and the Global Government Bond Portfolio, which can be
found on page three.

Although the equity portion of the Portfolio is managed similarly to the
International Equity Portfolio and the fixed-income portion is managed similarly
to the Global Government Bond Portfolio, there are some differences due to,
among other things, cash flow and the timing and availability of investment
opportunities. It is thus impossible to replicate performance. The International
Balanced Portfolio's relative underperformance was mainly due to the mid-cap
emphasis of the equity portion of the Portfolio as large-cap stocks continued to
outperform.

We thank you for your investment in the Smith Barney World Funds --
International Balanced Portfolio.

Sincerely,

(1)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value and does not reflect the deduction of the
     applicable sales charges with respect to Class A shares or the applicable
     contingent deferred sales charges ("CDSC") with respect to Class B and C
     shares.

(2)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A shares reflect the deduction
     of the maximum initial sales charge of 5.00%; Class B shares reflect the
     deduction of a 5.00% CDSC, which applies if shares are redeemed within one
     year from initial purchase. Thereafter, this CDSC declines by 1.00% per
     year until no CDSC is incurred. Class C shares reflect the deduction of a
     1.00% CDSC, which applies if shares are redeemed within the first year of
     purchase.

*    Inception dates for Class A, B, C and Y shares are August 25, 1994,
     November 7, 1994, August 25, 1994 and February 7, 1996, respectively.

+    Total return is not annualized, as it may not be representative of the
     total return for the year.

+    Hypothetical illustration of $10,000 invested in Class A and C shares at
     inception on August 25, 1994, assuming deduction of the maximum 4.50% sales
     charge at the time of investment for Class A shares and the deduction of
     the 1.00% CDSC for Class C shares. It also assumes reinvestment of
     dividends and capital gains, if any, at net asset value through April 30,
     1998. The Morgan Stanley Capital International ("MSCI") EAFE-GDP Weighted
     Index and MSCI EAFE Index are composite portfolios consisting of equity
     total returns for the countries of Europe, Australia, New Zealand and
     countries in the Far East. The MSCI EAFE-GDP Weighted Index is weighted
     based on each country's Gross Domestic Product and the MSCI EAFE Index is
     weighted based on each company's market capitalization. The J.P. Morgan
     Global Bond Market Index-Unhedged is a daily, market capitalization
     weighted international fixed income index consisting of 13 countries. The
     indexes are unmanaged and are not subject to the same management and
     trading expenses as a mutual fund. The performance of the Portfolio's other
     classes may be greater or less than the Class A and C shares' performance
     indicated on this chart, depending on whether greater or lesser sales
     charges and fees were incurred by shareholders investing in the other
     classes.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption values may be more or less than the original cost. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

++   It is the opinion of management that the MSCI EAFE Index is a more
     appropriate broad-based benchmark for the market in which the Portfolio
     invests than the MSCI EAFE-GDP Weighted Index. In future reporting, the
     MSCIEAFE Index will be used as a basis of comparison of total return
     performance rather than the MSCI EAFE-GDP Weighted Index.

1. Significant Accounting Policies

The Global Government Bond, International Equity and International Balanced
Portfolios ("Portfolios") are separate investment portfolios of the Smith Barney
World Funds, Inc. ("Fund"). The Fund, a Maryland corporation, is registered
under the Investment Company Act of 1940, as amended, as an open-end investment
management company and consists of these Portfolios and three other separate
investment portfolios: Emerging Markets, European and Pacific Portfolios. The
financial statements and financial highlights for the other portfolios are
presented in a separate semi-annual report.

The significant accounting policies consistently followed by the Portfolios are:
(a) security transactions are accounted for on trade date; (b) securities traded
on national securities markets are valued at the closing prices on the primary
exchange on which they are traded; securities listed or traded on certain
foreign exchanges or other markets whose operations are similar to the U.S.
over-the-counter market (including securities listed on exchanges where the
primary market is believed to be over-the-counter) and securities for which no
sales price was reported on that date are valued at the mean between the bid and
ask prices. Securities which are listed or traded on more than one exchange or
market are valued at the quotations on the exchange or market determined to be
the primary market for such securities; (c) securities maturing within 60 days
are valued at cost plus accreted discount, or minus amortized premium, which
approximates value; (d) gains or losses on the sale of securities are calculated
by using the specific identification method; (e) interest income, adjusted for
amortization of premium and accretion of discount, is recorded on an accrual
basis; (f) dividend income is recorded on the ex-dividend date; foreign dividend
income is recorded on the ex-dividend date or as soon as practical after the
Portfolio determines the existence of a dividend declaration after exercising
reasonable due diligence; (g) direct expenses are charged to each Portfolio and
each class; management fees and general Fund expenses are allocated on the basis
of relative net assets; (h) dividends and distributions to shareholders are
recorded on the ex-dividend date; (i) the accounting records of each Portfolio
are maintained in U.S. dollars. All assets and liabilities denominated in
foreign currencies are translated into U.S. dollars on the date of valuation.
Purchases and sales of securities, and income and expenses are translated at the
rate of exchange quoted on the respective date that such transactions are
recorded. Differences between income or expense amounts recorded and collected
or paid are adjusted when reported by the custodian; (j) the character of income
and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles. At
October 31, 1997, reclassifications were made to the capital accounts of the
Portfolios to reflect permanent book/tax differences and income and gains
available for distributions under tax regulations. Net investment income, net
realized gains and net assets were not affected by these changes; (k) each
Portfolio intends to comply with the applicable provisions of the Internal
Revenue Code of 1986, as amended, pertaining to regulated investment companies
and to make distributions of taxable income sufficient to relieve each Portfolio
from substantially all Federal income and excise taxes; and (l) estimates and
assumptions are required to be made regarding assets, liabilities and changes in
net assets resulting from operations when financial statements are prepared.
Changes in the economic environment, financial markets and any other parameters
used in determining these estimates could cause actual results to differ.

In addition, the Portfolios may enter into forward exchange contracts in order
to hedge against foreign

currency risk. These contracts are marked to market daily by recognizing the
difference between the contract exchange rate and the current market rate as an
unrealized gain or loss. Realized gains or losses are recognized when contracts
are settled.

2. Management Agreement and Other Transactions

Mutual Management Corp. ("MMC"), formerly known as Smith Barney Mutual Funds
Management Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"),
acts as investment manager of the Fund. The Global Government Bond Portfolio
pays MMC a management fee calculated at an annual rate of 0.75% of the average
daily net assets of the portfolio. The International Equity and International
Balanced Portfolios pay MMC a management fee calculated at an annual rate of
0.85% of the average daily net assets of each respective portfolio. These fees
are calculated daily and paid monthly.

Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor of the
Fund's shares. SB received sales charges of approximately $262,000 on sales of
the Portfolios' Class A shares for the six months ended April 30, 1998. In
addition, SB did not receive any brokerage commissions.

For the Global Government Portfolio, there is a contingent deferred sales charge
("CDSC") of 4.50% on Class B shares, which applies if redemption occurs within
one year from initial purchase. This CDSC declines by 0.50% the first year after
purchase and thereafter by 1.00% per year until no CDSC is incurred. For the
International Equity and International Balanced Portfolios, there is a CDSC of
5.00% on Class B shares, which applies if redemption occurs within one year from
initial purchase. Thereafter this CDSC declines by 1.00% per year until no CDSC
is incurred. Class C shares for each Portfolio have a 1.00% CDSC, which applies
if redemption occurs within the first year of purchase. In addition, Class A
shares for each Portfolio have a 1.00% CDSC, which applies if redemption occurs
within the first year of purchase. This CDSC only applies to those purchases of
Class A shares that equal or exceed $500,000 in the aggregate. These purchases
do not incur an initial sales charge.

For the six months ended April 30, 1998, CDSCs paid to SB were approximately:

Pursuant to a Distribution Plan, the Portfolios pay a service fee with respect
to Class A, B and C shares calculated at an annual rate of 0.25% of the average
daily net assets of each respective class's shares. The Global Government Bond
Portolio pays a distribution fee with respect to Class B and C shares calculated
at the annual rates of 0.50% and 0.45% of the average daily net assets of each
class, respectively. The International Equity and International Balanced
Portfolios pay a distribution fee with respect to Class B and C shares
calculated at an annual rate of 0.75% of the average daily net assets for each
respective Portfolio and class. For the six months ended April 30, 1998, total
Distribution Plan fees incurred by the Portfolios were:

5. Option Contracts

Premiums paid when put or call options are purchased by the Portfolios represent
investments, which are marked-to-market daily. When a purchased option expires,
the Portfolio will realize a loss in the amount of the premium paid. When the
Portfolio enters into a closing sales transaction, the Portfolio will realize a
gain or loss depending on whether the proceeds from the closing sales
transaction are greater or less than the premium paid for the option. When the
Portfolio exercises a put option, it will realize a gain or loss from the sale
of the underlying security and the proceeds from such sale will be decreased by
the amount of the premium originally paid. When the Portfolio exercises a call
option, the cost of the security that the Portfolio purchases upon exercise will
be increased by the permium originally paid.

At April 30, 1998, the Portfolios had no open purchased call or put options.

When a Portfolio writes a call or put option, an amount equal to the premium
received by the Portfolio is recorded as a liability, the value of which is
marked-to-market daily. When a written option expires, the Portfolio realizes a
gain. When the Portfolio enters into a closing purchase transaction, the
Portfolio realizes a gain or loss depending upon whether the cost of the closing
transaction is greater or less than the premium originally received, without
regard to any unrealized gain or loss on the underlying security, and the
liability related to such option is eliminated. When a written call option is
exercised the cost of the security sold will be decreased by the premium
originally received. When a written put option is exercised, the amount of the
premium originally received will reduce the cost of the security which the
Portfolio purchased upon exercise. When written index options are exercised,
settlement is made in cash.

The risk associated with purchasing options is limited to the premium originally
paid. The Portfolio enters into options for hedging purposes. The risk in
writing a call option is that the Portfolio gives up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Portfolio is
exposed to the risk of loss if the market price of the underlying security
declines.

During the six months ended April 30, 1998, the Portfolios did not write any
options.

6. Futures Contracts

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contract. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized gains or losses by "marking-to-market" on a daily basis to reflect
the market value of the contract at the end of each day's trading. Variation
margin payments are received or made and recognized as assets due from or
liabilities due to broker, depending upon whether unrealized gains or losses are
incurred. When the contract is closed, the Portfolio records a realized gain or
loss equal to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract.

The Portfolio enters into such contracts to hedge a portion of its portfolio.
The Portfolio bears the market risk that arises from changes in the value of the
financial instruments and securities indices (futures contracts).

At April 30, 1998, the Portfolios had no open futures contracts.

7. Lending of Portfolio Securities

The Portfolio has an agreement with their custodian whereby the custodian may
lend securities owned by the Portfolio to brokers, dealers, and other financial
organizations. Fees earned by the Portfolios on securities lending are recorded
as interest income. Loans of securities by the Portfolio are collateralized by
cash, U.S. government securities or high quality money market instruments that
are maintained at all times in an amount at least equal to the current market
value of the loaned securities, plus a margin which may vary depending on the
type of securities loaned. The Custodian establishes and maintains the
collateral in segregated accounts.

The Portfolios maintain exposure for the risk of any loss in the investment of
amounts received as collateral.

At April 30, 1998, the Portfolios listed below had loaned common stocks and
bonds. The market value for the securities on loan for each portfolio was as
follows:

8. Concentration of Risk

The Portfolios' investments in foreign securities may involve risks not present
in domestic investments. Since securities may be denominated in a foreign
currency and may require settlement in foreign currencies and pay interest or
dividends in foreign currencies, changes in the relationship of these foreign
currencies to the U.S. dollar can significantly affect the value of the
investments and earnings of each of the Portfolios. Foreign investments may also
subject the Portfolios to foreign government exchange restrictions,
expropriation, taxation or other political, social or economic developments, all
of which could affect the market and/or credit risk of the investments.

In addition to the risks described above, risks may arise from forward foreign
currency contracts with respect to the potential inability of counterparties to
meet the terms of their contracts.

9. Capital Loss Carryforwards

At October 31, 1997, the International Equity and International Balanced
Portfolios had, for Federal income tax purposes, approximately $73,386,000 and
$855,000, respectively, of capital loss carryforwards available to offset

10. Capital Shares

At April 30, 1998, the Fund had one billion shares of capital stock authorized
with a par value of $0.001 per share. The Portfolios have the ability to issue
multiple classes of shares. Each share of a class represents an identical legal
interest in a Portfolio and has the same rights, except that each class bears
certain expenses specifically related to the distribution of its shares.

At April 30, 1998, total paid-in capital amounted to the following for each
Portfolio:

(1)  For the six months ended April 30, 1998 (unaudited).

(2)  Per share amounts have been calculated using the monthly average shares
     method, rather than the undistributed net investment income method, because
     it more accurately reflects the per share data for the period.

(3)  For the period from January 1, 1994 to October 31, 1994.

(4)  Distributions from net investment income include short-term capital gains,
     if any, for Federal income tax purposes.

(5)  During the years ended October 31, 1996 and October 31, 1995, the Portfolio
     had earned credits from the custodian which reduced service fees incurred.
     If the credits are taken into consideration, the expense ratios for Class A
     would have been 1.24% and 1.32%, respectively; numbers prior to October 31,
     1995 have not been restated to reflect these credits.

*    Includes realized gains and losses from foreign currency transactions.

++   Total return is not annualized, as it may not be representative of the
     total return for the year.

Proposal 2 requested that shareholders approve certain changes to the
fundamental policies of the Fund in order to modernize them in view of certain
regulatory, business or industry developments that have occurred since original
adoption of these policies by the Fund. The following chart demonstrates that
all proposals were approved by shareholders.

Please note that "M" indicates a modification of the policy; "E" indicates the
elimination of the policy; and "R" indicates the reclassification of the policy
from fundamental (which would require shareholder approval to change) to
non-fundamental (which can be changed by a vote of the Board of Directors).

A Message from the Chairman

HEATH B. MCLENDON
Chairman


Dear Shareholder:

We are witnessing unparalleled prosperity in the United States today. As a
nation, we are more affluent than ever before, with much of that wealth created
in the last several decades. We are benefiting from a world that has been
largely at peace since the official end of the Cold War in 1989. We are reaping
the fruits of the restructuring of American businesses that took place in the
1970s and 1980s and we are benefiting from growth in worldwide demand for our
products.

This unparalleled U.S. prosperity is now being followed closely by Europe.
Companies there are undergoing restructuring similar to those in the U.S. of the
last two decades. More and more, the inefficiencies of state-controlled
institutions in Europe are being replaced with the expansion of a free and more
competitive marketplace. As we approach the dawn of a new millenium, these
positive developments have enabled both the U.S. and most of Europe to
experience the greatest period of peace and prosperity in generations.

The rapid rise of global markets in recent years has been helped in no small
measure by sophisticated monetary policy. In the U.S., policy-making bodies,
such as the Federal Reserve Board, coupled with technology-led productivity
gains, have controlled inflation to the extent that it is not a significant
factor in the U.S. economy today. This is also becoming true in Europe, where
the move to a common currency has forced both fiscal and monetary policies to
accomplish the same objective of bringing inflation and interest rates down
significantly in countries such as Italy and Spain. And as interest rates have
come down, investment funds have flowed into stock markets, which in turn have
helped propel dramatic gains in the U.S. and European financial markets.

Now, the developing world is taking its cue from the U.S. and Europe. Perhaps
the most meaningful example is Latin America, where after a very rocky period in
the last decade, monetary and fiscal policy reforms have stabilized its
economies and established a base for solid and sustainable future growth. For
example, Brazil, historically plagued by hyperinflation that reached as high as
2,500% per year, has now brought inflation down to manageable levels and plays a
larger role on the world stage today than ever before. Even lesser developed
countries in Eastern Europe and Africa are clearly demonstrating the positive
aspects of more freedom and greater competition.

The one area that is currently not enjoying growth and prosperity are parts of
Asia, particularly Japan, Southeast Asia and South Korea, where extraordinary
economic growth and expansion during the last several decades resulted in
overheated and overly extended financial conditions that are currently in the
painful process of readjustment.

For many years, U.S. investors had little reason to look beyond their own
shores. Over time, the U.S. market has rewarded patient investors with handsome
returns. However, as the world becomes a truly global and interdependent market,
it has become more important than ever for investors to remain globally
diversified. Despite the historic and outsized returns of the U.S. stock market
in recent years, the U.S. has yet to be the top-performing market in any one
year over the last two decades. We continue to believe that maintaining a
well-diversified portfolio with some international exposure is an essential key
to investing success.

Performance Update

For the six months ended April 30, 1998, the Emerging Markets Portfolio
("Portfolio") returned -2.89% for Class A shares before the deduction of any
sales charges. In comparison, the Portfolio's benchmark, the Morgan Stanley
Capital International ("MSCI") Emerging Markets Free Index, returned 2.66% for
the same period. For performance information on the Portfolio's other classes,
please refer to page six.

Emerging Markets Overview

In October 1997, expectations were very low for emerging markets, due to the
prolonged nature of the Asian crisis. The International Monetary Fund ("IMF"),
the usual medic for ailing economies, not only had enormous tasks in front of it
(i.e., Thailand, Indonesia, and South Korea), it was also coming under political
pressure. In spite of this, programs were implemented and, as more details
became known, markets started to stabilize. Now, due to the magnitude of the
situation in Asia, many investors believe IMF programs are not enough and are no
longer a major positive force for struggling emerging markets.

Coinciding with economic deterioration in Asia (which spread to other emerging
regions like Eastern Europe and Latin America) the U.S. and European stock
markets delivered excellent performance. Prior to 1998, U.S. stock market
strength and resiliency kept money from finding a home in emerging markets. Now,
emerging markets must compete with European market resurgence. Competition from
other markets and continuation of the Asian crisis has caused asset levels in
funds that invest in emerging markets to shrink drastically in recent months.

Asia

While Asia suffered badly in the final months of 1997, it recovered strongly in
the first months of 1998. It seemed countries like Thailand and South Korea were
finally coming to grips with their problems. Thailand closed down weak finance
companies and South Korea was preparing for a multi-billion dollar international
bond issue. It seemed the Asian crisis was going to be of a shorter duration
than was experienced in Latin America in 1994 and 1995.

However, euphoria was short-lived, as deeper problems came to the surface. Due
to the rapid restructuring in China, its economy was expected to slow which
heightened fears of another round of currency devaluations. At the same time,
the extent of the banking crisis in Malaysia came to light. When the stock
market fell, collateral levels also fell, taking loan values with them, creating
a vicious cycle that in turn drove Malaysian financial markets down even
further.

Similarly, South Korea first raised investor hopes with its March 1998 bond
offering and then fell from grace as the true extent of bankruptcies started to
be known. The industrial infrastructure was built on heavily indebted companies
that, due to slow economic growth, were unable to service their debt.

While most of Asia remains mired in financial turmoil, Taiwan has so far been
the most resilient country in the region. Its currency devalued along with the
rest of the region, but not nearly as much. Taiwan has a very strong local
economy and stock market, where local investors account for approximately 50% to
60% of stock market trading volumes. Inflation in the Taiwanese economy has been
under control for some time and is now actually declining. Moreover, we think a
positive economic environment should allow Taiwan's central bank to lower
interest rates in the next twelve months. Companies added to the Portfolio
during the reporting period are China Trust, a quality Taiwanese bank that
should benefit from lower interest rates, and Fubon Insurance, the leading
insurance company in Taiwan. We believe that both of these companies have strong
franchises and should see strong future earnings growth as interest rates
decline.

Latin America

Brazil continued to be the focus of investor attention at the end of 1997 and
the beginning of 1998. A strong monetary policy, low inflation and fiscal reform
have been the underpinnings of Brazil's economic recovery. It is this dependence
on monetary policy that forced the Brazilian central bank to almost double
interest rates in the wake of the Asian crisis. In order to add more control to
inflation, President Cardoso is pursuing reform of the welfare, subsidy and
pension system. Progress on the necessary reforms is gaining speed and we
believe they will take place in 1998. An important part of fiscal recovery is
the privatization program, mainly of electrical utilities and telecommunication
companies. In our view, this privatization should lead to more efficient
operating structures and enhanced earnings. The Portfolio continues to hold
electrical utilities and telecommunication stocks in Brazil. Since the last
reporting, we maintained our Brazilian positions and our exposure to this
country increased from roughly 12% to nearly 18% of assets.

Since its surprisingly fast progress toward economic recovery, Mexico has become
an emerging market success story. However, we decreased our exposure in Mexico
from approximately 16% to roughly 12% of assets during the reporting period. In
general, we sold stocks we believed to be in danger of not meeting first quarter
earnings estimates. For example, we sold Coca-Cola Femsa and Industrias Bachoco,
a chicken processor, when first quarter earnings estimates seemed too
optimistic. Exposure to the improving economy was maintained through Grupo
Televisa, Mexico's leading television and media company, and Grupo Banamex, a
leading Mexican bank. While Mexico appears to be on the road to recovery in
1998, we believe that careful stock selection in that country will be crucial to
good investment performance going forward.

Europe/Africa

The most recent country added to the portfolio was South Africa. In our opinion,
South Africa has long been overlooked by emerging market investors, in spite of
the fact that it is one of the largest country exposures in the MSCI Index
(approximately 12%). In the transition to new government, the economy has been
hamstrung by high interest rates. However, due to strong oversight from South
Africa's central bank, interest rates seem poised to go down. At the same time,
the largest insurance companies are expected to be demutualized, which means
large amounts of money will be transferred to consumers. In order to benefit
from these trends, the Portfolio has invested in two South African financial
companies: Liberty Life, a life insurer, and Nedcor, a commercial bank. Both
companies have strong market positions and should benefit from increased
liquidity spurred by lower interest rates and demutualization of insurance
companies.

In Central Europe, we continue to believe that Poland has the brightest
prospects in the region. Poland is proving to be very disciplined in the area of
financial management. Its currency has strengthened as confidence in Poland's
abilities to manage the economy grows. In 1998, Poland's policy-makers should
liberalize their markets, making it easier for foreign investors to invest, and
might possibly privatize their telecommunications company, TPSA. Elektrim, a
Polish cable and electrical equipment company, remains the Portfolio's second
largest holding. Not only does the stock present growth opportunities, as Poland
upgrades

its infrastructure, but Elektrim also has a large stake in a cellular
telephone operator.

After a strong year in 1997, Russia has faltered from an investment performance
standpoint. In our judgement, key reforms in tax collection must be implemented
to keep the market and economy on a growth path. President Yeltsin recently
reshuffled his entire cabinet and did not receive full-fledged support. Given
political uncertainty at a time when economic reforms are so crucial, and with
elections slated for 1999 and 2000, the outlook for Russia remains uncertain.
While problems exist, the Portfolio continues to hold Russian stocks, because we
believe they offer good value. Two of the largest holdings are in power
generation: Mosenergo, the power utility in Moscow, and Irkutsenergo, the
utility in Irkuts region that is expected to have future opportunities in China.
We expect both should increase earnings by controlling their cash and collection
rates. (Many companies in Russia are unable to collect all the money due them.)

Investment Strategy

During this period of emerging market turmoil, the Portfolio has remained
diversified by country and region. No single market has made up more than 20% of
the Portfolio's assets and 21 countries are currently represented in the
Portfolio. We believe that allocating assets across a wide range of countries
and regions has kept the Portfolio away from too much exposure to trouble spots,
such as the hard-hit countries of Asia.

At the end of October 1997, the Portfolio started building positions in markets
that appeared to be showing fundamentals expected to improve in the next 12
months. We maintained or increased our exposure to Brazil, Mexico, Turkey and
China. Brazil has been pursuing vigorous economic reforms that should keep
inflation low; Mexico seemed poised to experience a resurgence of economic
growth; Turkey, was taking measures to bring inflation down from previous levels
of near 100%; and China laid out a reform plan to rehabilitate its industrial
infrastructure.

We also focused on purchasing undervalued large-capitalization stocks,
especially those of telecommunications companies with strong growth prospects
and that we believed to be attractively priced. Prior to the end of 1997, the
Portfolio had limited exposure to telecommunications. But by the end of April
1998, telecommunications constituted 16% of the Portfolio. During the reporting
period, we added Telefonica Argentina, an Argentine company; CTC, the Chilean
telecommunications provider; VSNL, an Indian long distance provider; Telekom
Malaysia, the leading Malaysian telecommunications company; Telefonica de Peru,
the Peruvian operator; Digitel Telecomm, a niche-oriented Philippine operator;
and Advanced Information Systems, a Thai cellular provider. We believe that
these companies offer solid future growth prospects. They are leaders in their
respective markets, the attractiveness on an enterprise value versus earnings
before interest, tax, dividend and amortization basis and should play an
important role in an emerging market recovery.

Latin America remains the largest regional exposure of the Portfolio at 39%. In
our view, Brazil and Mexico have internal dynamics that should allow them to
stand on their own during 1998. Ongoing reforms, declining inflation and renewed
economic growth in Latin America should provide a good defense against the
further spread of the effects of the Asian contagion.

Outlook

We expect the next six months will continue to be a period of adjustment in the
emerging markets. But in the midst of all this, we will maintain broad
diversification and focus on exposure to stocks that will benefit early from the
turnaround in sentiment towards the emerging markets. As it is impossible to
time this point precisely, we continue to be fully invested.

Thank you for your investment in the Smith Barney World Funds, Inc. -- Emerging
Markets Portfolio.

     Free World Market Index measures performance for a diverse range of global
     stock markets, including the United States, Canada, Europe, Australia, New
     Zealand and the Far East and excludes shares which are not readily
     purchased by non-local investors. The MSCI Emerging Markets Free Index
     consists of emerging market companies with an average size of $800 million,
     the index measures performance of emerging markets in South America, South
     Africa, Asia and Eastern Europe. Each index is unmanaged and is not subject
     to the same management and trading expenses as a mutual fund.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption values may be more or less than the original cost. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

++   It is the opinion of management that the MSCI Emerging Markets Free Index
     is a more appropriate broad-based benchmark for the market in which the
     Emerging Markets Portfolio invests than the MSCI Free World Market Index.
     In future reporting, the MSCI Emerging Markets Free Index will be used as a
     basis of comparison of total return performance rather than the MSCI Free
     World Market Index.

Portfolio Manager

[PHOTO]
REIN W. VAN DER DOES
Vice President

Rein W. van der Does began his career with Drexel Burnham Lambert in 1968 as a
domestic research analyst. In 1975, he joined Drexel's International Research
Department and was appointed Director of International Research and Head of
Portfolio Strategy in 1985. He moved with the International Equity team to Smith
Barney in 1990. He is a member of the New York State Association for
International Investment and a member of the New York Society of Security
Analysts. Mr. van der Does was awarded a doctorate in Economics from the Dutch
Economic University in Rotterdam.

Performance Update

The European Portfolio ("Portfolio") posted a total return of 23.86% for Class A
shares, before the deduction of any sales charges, for the six months ended
April 30, 1998. In comparison, the Portfolio's benchmark, the Morgan Stanley
Capital International ("MSCI") European Market Index, had a total return of
29.26%. For performance information on the Portfolio's other classes, please
refer to page 11. 

We are pleased to announce that your Portfolio was awarded a four-star rating
from Morningstar, Inc.* overall and for the three-year period ended March 31,
1998 for Class A, B and C shares. Past performance is not a guarantee of future
results.

During the reporting period, investors in European stock markets continued to
favor larger, better-known companies over mid-sized companies like the ones
emphasized in the Portfolio. In 1997, investor preference for big company shares
penalized the Portfolio's performance somewhat. However, we believe that there
is growing evidence that the performance of European stock markets is beginning
to broaden and this has helped boost the Portfolio's performance. In fact, in
the first four months of 1998, the Portfolio appreciated roughly 29%.

European Markets Update 

European stock markets have soared in the past six months, fueled by heavy
corporate restructuring and the ongoing drive toward economic and monetary
unification. In particular, the smaller economies of Southern Europe posted
blistering market returns. The stock markets of Portugal, Italy and Spain all
returned more than 40% in the first quarter of this year.

The European Union ("EU"), with its aim of integrating the major European
economies and their currencies, took center stage in nearly all political and
economic discussions during the reporting period. On March 25, 1998, the
European Commission and European Monetary Institute (the forerunner of a
pan-European central bank) announced eleven countries that will be included in
the first round of membership in the EU, which will commence on January 1, 1999.
Those countries are: Germany, France, the Netherlands, Belgium, Luxembourg,
Austria, Finland, Ireland, Italy, Spain and Portugal. Other countries, most
notably the United Kingdom, have qualified for membership, but have declined to
participate in the first round of EU membership.

One of the chief criteria of membership in the EU is maintaining a budget
deficit of roughly 3% of the prospective country's Gross Domestic Product

*    Morningstar, Inc. proprietary ratings reflect historical risk-adjusted
     performance through March 31, 1998. The ratings are subject to change every
     month. Morningstar, Inc. ratings are calculated from the Portfolio's
     three-year returns (including the effects of all fees and sales charges) in
     excess of 90-day T-bill returns and a risk factor that reflects fund
     performance below 90-day T-bill returns. Different classes within a fund
     share a common portfolio of securities. The top-performing ten percent of
     the funds in a rating category receive five stars; the next 22.5% of the
     funds receive four stars; the middle 35% receive three stars; the next
     22.5% receive two stars; and the bottom 10% receive one star. The Portfolio
     was rated among 722 international equity funds.

("GDP"). Just a few years ago, this budget deficit target seemed impossibly out
of reach for many European countries used to carrying budget deficits three to
four times the 3% level. Today, as governments have implemented fiscal reforms,
interest rates have fallen across Europe and, in our opinion, have been largely
responsible for the Europe's recent economic upturn.

Another important development leading to Europe's recent economic successes has
been the rise of a true equity culture. As part of the effort to lower spending,
a number of governments are transforming key industries from state-controlled to
privately held companies. In several countries, government-sponsored pension and
retirement plans are also undergoing privatization. Moreover, many European
companies are increasingly focusing on rewarding their shareholders. Similar to
the U.S. in the 1970s and 1980s, European corporations have been undertaking
mergers and acquisitions at a feverish pace. The total value of completed
acquisitions of public companies in Europe rose nearly 37% in 1997. That trend
seems to be only accelerating. In our view, this process of corporate
restructuring in Europe is just beginning and should help drive profits in the
near future.

Investment Strategy

In selecting investments for the Portfolio, we continue to use a "bottom-up"
approach, evaluating individual companies rather than investment trends. While
economic cycles are important when evaluating a company's outlook, we generally
search for promising European companies with excellent growth prospects
regardless of the macroeconomic conditions in Europe. In our opinion, this
approach should provide investors with competitive returns over the long term.

During the reporting period, we found a number of attractive investment
opportunities. For example, we added to our position in Nokia, the Finnish
cellular phone giant, after uncertainties in Asia cast a pall over the industry.
We believe that Nokia's prospects remain bright. At the close of the reporting
period, Nokia remained the Portfolio's top holding representing 6.4% of the
Portfolio's total stocks held. Other significant additions to the Portfolio
include the Ordina, NV and SEMA, PLC.

European Markets Outlook

In our opinion, investing in Europe should be exciting and rewarding in the next
few years due to:

o    The creation of the European Union in January, 1999;

o    The creation of a single currency, the Euro;

o    The creation of an equity culture through relatively inexpensive
     privatization offerings; and

o    The discovery by European companies of the concept of "enhancing
     shareholder value."

Thank you for your investment in the Smith Barney World Funds, Inc. -- European
Portfolio.

Performance Update

During the six-month period ended April 30, 1998, the Pacific Portfolio
("Portfolio") Class A shares declined by 9.93%, performing in line with the
benchmark Morgan Stanley Capital International (MSCI) All Country Asia Pacific
Index, which was down by 9.20% for the same period. (The MSCI All Country Asia
Pacific Index, comprising equities in Australia, New Zealand, Japan and the Far
East, is a common benchmark against which the performance of Asian funds is
measured.) During the first quarter of the fiscal year (the period of November
1997 to January 1998), the Portfolio underperformed the benchmark because of its
underweighteded position in Japanese equities. For performance information on
the Portfolio's other classes, please refer to page 17.

So far in the second quarter, the situation has reversed, as Asian markets
(excluding Japan) rebounded sharply, helping the Portfolio to catch up with the
benchmark. We believe the worst of the financial meltdown in Asia is over and
that adjustments currently underway will lead to economic recovery for most
countries over the next 12 to 18 months.

Asian Market Review--The Meltdown is Over and Markets Rally in Relief
Asia Excluding Japan

After suffering a free fall during the second half of 1997, Asian stock prices
continued to slide in January, but finally hit bottom in February and rebounded
sharply. This rebound, while good news for battered Asian investors, was not so
much an indication of bright prospects for Asian economies as it was a
relief-rally that the worst may be over. Positive political and economic
developments continued into March and investors felt comfortable buying oversold
Asian blue chips.

<PAGE>
 
Several events triggered this turnaround in market sentiment. First, initiatives
taken by the South Korean and Thai governments in conjunction with the
International Monetary Fund ("IMF") brought hope that necessary structural
reforms would finally begin. The announcement of the South Korean bank deal in
late January was an especially important signal. (The South Korean government
announced that it agreed to guarantee the loans of local banks and issue bonds,
in exchange for foreign commercial banks agreeing to rollover short-term loans
to the banking system). Another important, but less-publicized, factor was
China's decision not to devalue the renmenbi, easing fears of another round of
damaging currency falls in the region. Finally, the lack of runaway inflation
had a stabilizing effect, reducing the need for high interest rates and keeping
currencies at attractive levels in real terms.

Japan

The Japanese stock market was out of sync with the rest of Asia, rising 12% in
U.S. dollar terms during January while regional markets fell. Investors were
hopeful that the thirty trillion yen financial package (about $250-$300 billion)
proposed by the government to provide better support for depositors, shore-up
the banking system and ease capital adequacy controls, would finally get the
Japanese economy back on track. However, government unwillingness to combine
this package with tax cuts, deregulation and financial restructuring, tarnished
the long-term outlook for growth in the Japanese economy and caused investors to
lose confidence. The stock market was flat in February and fell by 7% in March,
just when the rest of Asia was rallying strongly.

Outlook for Second Half--The Crash Is Over, Now Comes the Hard Part....

We believe that the worst of Asia's crisis is probably over, but the pain of
adjustment is only beginning to be felt. Recessions are unfolding across Asia,
with Indonesia (1998 GDP estimated to decline by 10%), Korea and Thailand (-4%
each) hit the hardest by last year's contagion. Malaysia, despite government
efforts, is now expected to fall into recession and the Philippines is
struggling to maintain growth at just above zero. Hong Kong and Singapore will
be hit harder than expected, affected by the sharp slowdown in neighboring
countries, and China will not meet its 8% growth target. Australia and New
Zealand escaped the financial turmoil suffered by regional neighbors, but their
growth prospects will be undermined by slower trade.

The short-term outlook for Japan also is poor, with the economy increasingly
looking like it's headed into recession. Japan's long period of economic
stagnation and recent, ineffective attempts at boosting the economy indicate
that a sustained recovery cannot be achieved without deep structural and,
especially, financial reform. This requires strong political will and the
ability to suffer through painful reforms in order to emerge with a clean,
efficient and reinvigorated economy. The Japanese government has preferred to
maintain the status quo, using low interest rates and other funds to stave off a
meltdown, but this has not solved the country's structural problems. This has
important implications for the rest of Asia. First, a weak Japanese economy and
yen pose a double threat to Asian economies, since Japan is a major export
destination as well as the home of competitors and investors. Second, other
countries would do well to avoid the Japanese model and grasp the thorny nettles
of reform as the best way out of recession. Indeed, they will need to show
progress in real reform in order to attract the capital required for
restructuring.

Portfolio Changes

We expect most countries in Asia to suffer recession or, at best, slow growth in
1998 as policy-makers and corporations struggle through the reform process.
However, we are optimistic that these reform efforts will be successful, and we
look for growth in many countries to resume in 1999-2000. Going forward, we
expect Asian stocks to perform strongly next year.

The key question for Asian investors is how to best position themselves for the
economic adjustment

period, which we feel is likely to last 12 months or so, and the recovery that
follows. We have several thoughts on this matter.

First, while we remain skeptical of the Japanese government's efforts to
stimulate the economy, we find the Japanese stock market relatively less
volatile than other markets in the region at this time. Accordingly, we have
increased our exposure to high-quality Japanese companies, raising our weighting
to 50% of the Portfolio from 30% previously. New Japanese companies added during
the period include Aiful and Takefuji, two small-business and consumer lenders,
NTT Data Communication, Japan's major information technology company, and
Terumo, the second largest supplier of medical equipment in the world. In
addition, we increased our weighting in Meitec, Minebea, Murata Noritsu Koki and
Sony. Japan now accounts for seven of our top ten holdings, up from two six
months ago.

Second, we believe that currency devaluations have made Asian products very
competitive in world markets and we expect exporters to thrive in the current
environment. As a result, we have built positions in selected exporters that are
trading at very attractive levels currently and that we expect can grow earnings
over the next few years. These companies include Samsung Display Devices, one of
the largest producers in the world of cathode ray tubes and computer monitors,
Youngone Corp., a South Korean garment manufacturer, Delta Electronics, a Thai
manufacturer of components for laptop and desktop computers, and GSS Array, a
contract manufacturer for electronics, also based in Thailand.

Third, we are optimistic about the prospects for recovery in those countries
where governments are implementing reforms aggressively and working closely with
the IMF, including Thailand and South Korea. At the same time, we are uneasy
with those countries where governments are resisting change and fighting with
the IMF, including Indonesia and Malaysia. Not surprisingly, our weightings in
South Korea and Thailand have increased to 5% and 10%, respectively, while we
have deleted Indonesia from the Portfolio and reduced Malaysia to a 2%
weighting.

Fourth, the Pacific Basin is home to many world-class blue chip companies that
will survive the crisis and likely will emerge stronger as a result. However, it
is unrealistic to expect much in the way of performance from these companies
during 1998, as higher costs and slower economic growth will cause short-term
problems. We believe such companies will benefit in the long run, as they buy
and consolidate weaker competitors, and that their shares should be accumulated
gradually. In the meantime, we have trimmed back holdings in both Hong Kong and
Singapore blue chips.

Thank you for your investment in the Smith Barney World Funds, Inc. -- Pacific
Portfolio.

1.   Significant Accounting Policies

The Emerging Markets, European and Pacific Portfolios ("Portfolios") are
separate investment portfolios of the Smith Barney World Funds, Inc. ("Fund").
The Fund, a Maryland corporation, is registered under the Investment Company Act
of 1940, as amended, as an open-end investment management company. The Fund
consists of these Portfolios and three other separate investment portfolios:
Global Government Bond, International Equity and International Balanced
Portfolios. The financial statements and financial highlights for the other
portfolios are presented in a separate semi-annual report.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities traded on
national securities markets are valued at the closing prices on the primary
exchange on which they are traded; securities listed or traded on certain
foreign exchanges or other markets whose operations are similar to the U.S.
over-the-counter market (including securities listed on exchanges where the
primary market is believed to be over-the-counter) and securities for which no
sales price was reported on that date are valued at the mean between the bid and
ask prices. Securities which are listed or traded on more than one exchange or
market are valued at the quotations on the exchange or market determined to be
the primary market for such securities; (c) securities maturing within 60 days
are valued at cost plus accreted discount, or minus amortized premium, which
approximates value; (d) gains or losses on the sale of securities are calculated
by using the specific identification method; (e) interest income, adjusted for
amortization of premium and accretion of discount, is recorded on an accrual
basis; (f) dividend income is recorded on the ex-dividend date; foreign dividend
income is recorded on the ex-dividend date or as soon as practical after the
Fund determines the existence of a dividend declaration after exercising
reasonable due diligence; (g) direct expenses are charged to each Portfolio and
class; management fees and general Portfolio expenses are allocated on the basis
of relative net assets by class; (h) dividends and distributions to shareholders
are recorded on the ex-dividend date; (i) the accounting records of each
Portfolio are maintained in U.S. dollars. All assets and liabilities denominated
in foreign currencies are translated into U.S. dollars on the date of valuation.
Purchases and sales of securities, and income and expenses are translated at the
rate of exchange quoted on the respective date that such transactions are
recorded. Differences between income or expense amounts recorded and collected
or paid are adjusted when reported by the custodian; (j) the character of income
and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles. At
October 31, 1997, reclassifications were made to the capital accounts of the
Portfolios to reflect permanent book/tax differences and income and gains
available for distributions under tax regulations. Accordingly, a portion of net
investment loss amounting to $285,646, $507,347 and $181,481 was reclassified to
paid-in capital for the Emerging Markets, European and Pacific Portfolios,
respectively. Net investment income, net realized gains and net assets were not
affected by these adjustments; (k) each Portfolio intends to comply with the
applicable provisions of the Internal Revenue Code of 1986, as amended,
pertaining to regulated investment companies and to make distributions of
taxable income sufficient to relieve each Portfolio from substantially all
Federal income and excise taxes; and (l) estimates and assumptions are required
to be made regarding assets, liabilities and changes in net assets resulting
from operations when financial statements are prepared. Changes in the economic
environment, financial markets and any other parameters used in determining
these estimates could cause actual results to differ.

In addition, the Portfolios may enter into forward exchange contracts in order
to hedge against foreign currency risk. These contracts are marked-to-market
daily by recognizing the difference between the contract exchange rate and the
current market rate as an unrealized gain or loss. Realized gains or losses are
recognized when contracts are settled.

2. Management Agreement and Other Transactions

Mutual Management Corp. ("MMC"), formerly known as Smith Barney Mutual Funds
Management Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"),
acts as investment manager of the Fund. The European and Pacific Portfolios pay
MMC a management fee calculated at an annual rate of 0.85% of the average daily
net assets of each respective Portfolio. The Emerging Markets Portfolio pays
MMCa management fee calculated at an annual rate of 1.00% of the average daily
net assets of the Portfolio. These fees are calculated daily and paid monthly.

Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor of the
Fund's shares. SB received sales charges of approximately $57,000 on sales of
the Portfolios' Class A shares for the six months ended April 30, 1998.

For the Emerging Markets, European and Pacific Portfolios, there is a contingent
deferred sales charge ("CDSC") of 5.00% on Class B shares, which applies if
redemption occurs within one year from initial purchase. Thereafter this CDSC
declines by 1.00% per year until no CDSC is incurred. Class C shares for each
Portfolio have a 1.00% CDSC, which applies if redemption occurs within the first
year of purchase. In addition, Class A shares for each Portfolio have a 1.00%
CDSC, which applies if redemption occurs within the first year of purchase. This
CDSC only applies to those purchases of Class A shares that equal or exceed
$500,000 in the aggregate. These purchases do not incure an initial sales
charge.

For the six months ended April 30, 1998, CDSCs paid to SB were approximately:

Pursuant to a Distribution Plan, the Portfolios pay a service fee with respect
to Class A, B and C shares calculated at the annual rate of 0.25% of the average
daily net assets of each respective class' shares. The Portfolios also pay a
distribution fee with respect to Class B and C shares calculated at the annual
rate of 0.75% of the average daily net assets for each respective Portfolio and
class. For the six months ended April 30, 1998, total Distribution Plan fees
incurred by the Portfolios were:

5.   Option Contracts

Premiums paid when put or call options are purchased by the Portfolios represent
investments, which are marked-to-market daily. When a purchased option expires,
the Portfolio will realize a loss in the amount of the premium paid. When the
Portfolio enters into a closing sales transaction, the Portfolio will realize a
gain or loss depending on whether the proceeds from the closing sales
transaction are greater or less than the premium paid for the option. When the
Portfolio exercises a put option, it will realize a gain or loss from the sale
of the underlying security and the proceeds from such sale will be decreased by
the amount of the premium originally paid. When the Portfolio exercises a call
option, the cost of the security that the Portfolio purchases upon exercise will
be increased by the premium originally paid.

At April 30, 1998, the Portfolios had no open purchased call or put options.

When a Portfolio writes a call or put option, an amount equal to the premium
received by the Portfolio is recorded as a liability, the value of which is
marked-to-market daily. When a written option expires, the Portfolio realizes a
gain equal to the amount of the premium received. When the Portfolio enters into
a closing purchase transaction, the Portfolio realizes a gain or loss depending
upon whether the cost of the closing transaction is greater or less than the
premium originally received without regard to any unrealized gain or loss on the
underlying security, and the liability related to such option is eliminated.
When a written call option is exercised, the cost of the security sold will be
decreased by the premium originally received. When a written put option is
exercised, the amount of the premium originally received will reduce the cost of
the security that the Portfolio purchased upon exercise. When written index
options are exercised, settlement is made in cash.

The risk associated with purchasing options is limited to the premium originally
paid. The Portfolio enters into options for hedging purposes. The risk in
writing a call option is that the Portfolio gives up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Portfolio is
exposed to the risk of a loss if the market price of the underlying security
declines.

During the six months ended April 30, 1998, the Portfolios did not write any
call or put options.

6.   Futures Contracts

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contract. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized gains or losses by "marking-to-market" on a daily basis to reflect
the market value of the contract at the end of each day's trading. Variation
margin payments are received or made and recognized as assets due from or
liabilities due to broker, depending upon whether unrealized gains or losses are
incurred. When the contract is closed, the Portfolio records a realized gain or
loss equal to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract. The Portfolio enters
into such contracts to hedge a portion of its portfolio. The Portfolio bears the
market risk that arises from changes in the value of the financial instruments
and securities indices (futures contracts).

At April 30, 1998, the Portfolios had no open futures contracts.

7.   Concentration of Risk

The Portfolios' investments in foreign securities may involve risks not present
in domestic investments. Since securities may be denominated in a foreign
currency

================================================================================

and may require settlement in foreign currencies and pay interest or dividends
in foreign currencies, changes in the relationship of these foreign currencies
to the U.S. dollar can significantly affect the value of the investments and
earnings of each of the Portfolios. Foreign investments may also subject the
Portfolios to foreign government exchange restrictions, expropriation, taxation
or other political, social or economic developments, all of which could affect
the market and/or credit risk of the investments.

In addition to the risks described above, risks may arise from forward foreign
currency contracts with respect to the potential inability of counterparties to
meet the terms of their contracts.

8.   Capital Loss Carryforwards

At October 31, 1997, the Emerging Markets and Pacific Portfolios had, for
Federal income tax purposes, approximately $925,000 and $2,224,000,
respectively, of capital loss carryforwards available to offset future realized
gains. To the extent that these carryforward losses are used to offset gains, it
is probable that the gains so offset will not be distributed. The amount and
date of expiration of the carryforward losses for each Portfolio is indicated
below:

9.   Lending of Portfolio Securities

The Portfolios have an agreement with their custodian whereby the custodian may
lend securities owned by the Portfolios to brokers, dealers and other financial
organizations. Fees earned by the Portfolios on securities lending are recorded
as interest income. Loans of securities by the Portfolios are collateralized by
cash, U.S. government securities or high quality money market instruments that
are maintained at all times in an amount at least equal to the current market
value of the loaned securities, plus a margin depending on the type of
securities loaned. The custodian establishes and maintains the collateral in a
segregated account. The Portfolios maintain exposure for the risk of any losses
in the investment of amounts received as collateral.

At April 30, 1998, the Emerging Markets, European and Pacific Portfolios loaned
common stock having a value of approximately $4,257,859, $8,272,388 and
$516,833, respectively, and the Portfolios hold the following collateral for
loaned securities:

(2)  Per share amounts have been calculated using the monthly average shares
     method, rather than the undistributed net investment income method, because
     it more accurately reflects the per share data for the period.
(3)  For the period from May 12, 1995 (inception date) to October 31, 1995.
(4)  The Manager waived all or part of its fees for the period ended October 31,
     1995. If such fees were not waived, the per share effect on net investment
     loss and the expense ratio would have been as follows:

     In addition, during the years ended October 31, 1996 and October 31, 1995,
     the Portfolio had earned credits from the custodian which reduced service
     fees incurred. If the credits are taken into consideration, the expense

     commission rate of $0.06 per share. Commission on trades executed outside
     these countries generally are executed as a percentage of cost or proceeds
     ranging from 0.50% to 1.00%. The European Portfolio paid commissions which
     equaled an average rate of 0.30% on the total of either cost or proceeds on
     executed trades, which is below the average range. While the amount of
     commissions paid is reasonable on a percentage basis, the commission per
     share amount appears high because these securities were trading at a very
     large dollar amount per share, which is atypical of the way U.S. or
     Canadian companies' shares trade. As a result, since less shares trade for
     a comparable dollar amount than would ordinarily be the case in the U.S. or

     In addition, during the years ended October 31, 1996 and October 31, 1995,
     the Portfolio had earned credits from the custodian which reduced service
     fees incurred. If the credits are taken into consideration, the expense
     ratios for Class C would have been 2.50% and 2.48%, respectively; numbers

(6)  As of September 1995, the SEC instituted new guidelines requiring the
     disclosure of average commissions per share.
(7)  Trades executed in the United States and Canada are executed at an average
     commission rate of $0.06 per share. Commission on trades executed outside
     these countries generally are executed as a percentage of cost or proceeds
     ranging from 0.50% to 1.00%. The European Portfolio paid commissions which
     equaled an average rate of 0.30% on the total of either cost or proceeds on
     executed trades, which is below the average range. While the amount of
     commissions paid is reasonable on a percentage basis, the commission per
     share amount appears high because these securities were trading at a very
     large dollar amount per share, which is atypical of the way U.S. or
     Canadian companies' shares trade. As a result, since less shares trade for
     a comparable dollar amount than would ordinarily be the case in the U.S. or
     Canada, the commission per share amount skewed upward.

Proposal 2 requested that shareholders approve certain changes to the
fundamental policies of the Fund in order to modernize them in view of certain
regulatory, business or industry developments that have occurred since original
adoption of these policies by the Fund. The following chart demonstrates that
all proposals were approved by shareholders.

Please note that "M" indicates a modification of the policy; "E" indicates the
elimination of the policy; and "R" indicates the reclassification of the policy
from fundamental (which would require shareholder approval to change) to
non-fundamental (which can be changed by a vote of the Board of Directors).
