Pioneer Emerging Markets Fund

LETTER FROM THE CHAIRMAN 11/30/97
Dear Shareowner,
- --------------------------------------------------------------------------------

   
I am pleased to present this report for Pioneer Emerging Markets Fund, covering
its fiscal year ended November 30, 1997. I thank you
for your interest and this opportunity to comment briefly on today's investing
environment.

Since October, the world's emerging markets have taken on a whole new look.
After a 12-year period of tremendous growth, Southeast Asia is facing
tremendous financial and economic setbacks, and stock markets and currencies
there have plunged to nearly unimaginable depths. European markets have bounced
around, heartened by the relative strength of the U.S. stock market but shaken
by the drop in Asia. In today's truly global economy, Latin America is feeling
pressures on currency and interest rates. It is difficult to say when and how
Asia's vast difficulties will be resolved and what the real effects will be on
companies and countries there and in other regions.

One thing is clear, however. Over the past year, as is so often the case with
emerging markets, it did not pay to share the group mentality of investors who
piled out of Asia in near unison. I am pleased to say that thinking
independently helped your Fund make 1997 a profitable year. Your investment
team's willingness to invest in a "contrarian" manner - where research and
logic show long-term opportunity rather than where popular opinion may reside
in the short term - proved to be the difference between investment success and
disappointment.

I encourage you to read on to learn more about Pioneer Emerging Markets Fund
and your investment team's strategy. If you have questions about your Fund,
please contact your investment professional, or Pioneer at 1-800-225-6292.

Respectfully,
    

/s/ John F. Cogan, Jr.

   
John F. Cogan, Jr.,
Chairman and President
    

                                                                               1

Pioneer Emerging Markets Fund

PORTFOLIO MANAGEMENT DISCUSSION 11/30/97
Dear Shareowner,
- --------------------------------------------------------------------------------

   
We are pleased to report that Pioneer Emerging Markets Fund delivered strong
performance in a year that ended amid much turmoil in Southeast Asia. Shifting
assets out of the Pacific Rim into Latin America, Israel and India proved
constructive for the 12 months ended November 30, 1997, and helped your Fund
avoid much of the Asian currency and stock market fallout.

The Fund generated one-year total returns of around 10% at net asset value
(NAV). This performance is particularly gratifying in light of the -13.28%
return of the MSCI Emerging Markets Free Index. The Fund's one-year NAV returns
surpassed 85% of the 128 emerging market funds followed by Lipper Analytical
Services, Inc.*

Southeast Asia at a Crossroads
Since the devaluation of Thailand's currency on July 2, Asia has been hit hard
by dramatic stock market sell-offs, slowing economic growth and falling
currency values. The troubles of the most distressed countries - notably Korea
and Thailand - have spilled into the rest of the region and across the world in
the form of declining sales and corporate earnings, weakened balance sheets and
increased skepticism about emerging markets. It's safe to say most investors
are looking at Asia with a new view since Hong Kong's stock market sparked a
global selloff in late October.

We had identified many of the difficulties now plaguing Asia early in the year.
Short-sighted economic policies, overextended banks and relatively high stock
prices were some of the reasons we trimmed Asian investments as early as
January. As a result, holdings in Thailand, South Korea, Indonesia, the
Philippines and Malaysia represented just 11% of equity holdings on May 31 and
9% by November, less than half of what they were a year ago. The Asian
companies in the portfolio today are poised to benefit from export-led growth
boosted by the new lows in local currencies. Delta Electronics in Thailand, for
example, has a high export ratio, which has already helped cushion operating
results.

Many analogies are being drawn between Asia's current state and the Mexican
peso crisis in 1994 and the painful U.S. corporate restructuring of the early
1990s. Bad loans, real estate excesses, bank failures and a unique brand of
centrally controlled capitalism now characterize the Pacific Rim. If Asian
governments take a short-sighted or "do-nothing" approach, the crisis will be
prolonged. We are closely monitoring the situation, and we intend to limit
investments in Asia until we see policy makers making the tough decisions
required to put their economies on track to recovery.

Fastest Growing Markets--Brazil, Mexico, Israel and India
While Brazil, Mexico, Israel and India were not immune to the changing fortunes
of Southeast Asia, they are further along in their economic cycles and their
transition to free-market economies. These countries comprised 62% of equity
holdings on November 30, 1997, and were the main reasons for your Fund's
standout performance throughout the year.

As Latin America's largest economy, Brazil is closely watched as a barometer of
the region's growth prospects. Its currency has been under pressure since Hong
Kong's market fell, leading its central bank to raise interest rates in an
effort to prevent currency devaluation. Nevertheless, voters appear to be
pleased with President Cardoso's efforts to promote free-market policies, and
we're optimistic that further reforms will go forward. Deregulation and
privatization of state-owned enterprises continue as major focuses for the
Fund, with Telecomunicacoes Brasileiras (telecommunications), Petroleo
Brasileiro (oil and gas) and Centrais Electricas Brasileiras (electric utility)
all top holdings. They proved profitable for the year, even though their stock
prices took a wild ride in the past few months.

It's been a decade since Latin America began opening its markets. Today its
companies are emerging as world-class competitors headed by a new breed of
savvy, U.S.-trained executives who are moving beyond national borders. In
Mexico, Grupo Televisa is the world's largest Spanish-language media company,
broadcasting from four countries. Cifra, a Wal-Mart-controlled retailer, is
benefiting from general economic prosperity. Grupo Radio Centro, a major radio
station in Mexico City, is enjoying rising advertising revenues fueled by the
pursuit of the emerging Mexican consumer.

With a variety of dynamic, seasoned companies and a gross domestic product of
$17,000 per capita, Israel is an anomaly among emerging

markets. But uncertainty about the future of the peace process continues to
overshadow this corner of the globe, creating attractive valuations. Software
developers Formula Systems and Oshap Technologies enjoyed substantial increases
in stock price; late in the year we scaled backed Formula Systems and sold out
of Oshap Technologies to lock in profits. Tadiran is a leading-edge
telecommunications equipment provider and performed well.

Holdings in India rose to about 10% of equity assets by November 30. While
infighting remains prevalent among political factions, we were heartened to see
the government pass a responsible budget in February that lowered corporate and
personal income taxes. In September, they enacted long-awaited policies to
reduce the government budget deficit. Holdings Reliance Industries (chemicals)
and Videsh Sanchar Nigam (telecommunications), reacted favorably to the news.
India remains a complex market, often hampered by inefficient bureaucracy and
inadequate infrastructure. Nevertheless, the latest round of reforms are
evidence of policymakers' commitment to steady growth and their pledge to make
India a more attractive country for foreign investment, regardless of political
differences.

Looking Forward
The world's financial markets are likely to stay choppy in the months ahead. We
expect Asia's troubles will reduce global economic growth in 1998 and 1999.
With the region's stock markets now down some 70% from recent levels, and stock
valuations at eight- to 10-year lows, we are excited about the investment
opportunities we expect to surface in Asia. We're confident we can continue to
provide shareowners with a unique investment opportunity by continuing our
disciplined, research-driven, value-oriented approach - rather than running
with the herd.


Respectfully,

 NOTES TO FINANCIAL STATEMENTS 11/30/97

1. Organization and Significant Accounting Policies

Pioneer Emerging Markets Fund (the Fund) is a Delaware business trust
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Fund is to seek
long-term growth of capital by investing primarily in securities of issuers in
countries with emerging economies or securities markets.

The Fund offers three classes of shares - Class A, Class B and Class C shares.
Shares of Class A, Class B and Class C each represent an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class
A, Class B and Class C shareholders, respectively.

The Fund's financial statements have been prepared in conformity with generally
accepted accounting principles that require the management of the Fund to,
among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts
of revenues and expenses during the reporting periods. Actual results could
differ from those estimates. The following is a summary of significant
accounting policies consistently followed by the Fund, which are in conformity
with those generally accepted in the investment company industry:

A. Security Valuation
  Security transactions are recorded on trade date. Each day, securities are
  valued at the last sale price on the principal exchange where they are
  traded. Securities that have not traded on the date of valuation, or
  securities for which sale prices are not generally reported, are valued at
  the mean between the last bid and asked prices. Securities for which market
  quotations are not readily available are valued at their fair values as
  determined by, or under the direction of, the Board of Trustees. Trading in
  foreign securities is substantially completed each day at various times
  prior to the close of the New York Stock Exchange. The values of such
  securities used in computing the net asset value of the Fund's shares are
  determined as of such times. Dividend income is recorded on the ex-dividend
  date, except that certain dividends from foreign securities where the
  ex-dividend date may have passed are recorded as soon as the Fund is
  informed of the ex-dividend data in the exercise of rea-

                                                                              21

  sonable diligence. Interest income is recorded on the accrual basis, net of
  unrecoverable foreign taxes withheld at the applicable country rates.
  Temporary cash investments are valued at amortized cost.

  Gains and losses on sales of investments are calculated on the identified
  cost method for both financial reporting and federal income tax purposes. It
  is the Fund's practice to first select for sale those securities that have
  the highest cost and also qualify for long-term capital gain or loss
  treatment for tax purposes.

  The Fund's investments in emerging markets or countries with limited or
  developing markets may subject the Fund to greater degree of risk than in a
  developed market. Risks associated with these developing markets include
  political, social or economic factors and may affect the price of the Fund's
  investments and income generated by these investments, as well as the Fund's
  ability to repatriate such amounts. In addition, delays are common in
  registering transfers of securities in India, and the Fund may be unable to
  sell portfolio securities until the registration process is completed.

B. Foreign Currency Translation
  The books and records of the Fund are maintained in U.S. dollars. Amounts
  denominated in foreign currencies are translated into U.S. dollars using
  current exchange rates.

  Net realized gains and losses on foreign currency transactions represent,
  among other things, the net realized gains and losses on foreign currency
  contracts, disposition of foreign currencies and the difference between the
  amount of income accrued and the U.S. dollar actually received. Further, the
  effects of changes in foreign currency exchange rates on investments are not
  segregated in the statement of operations from the effects of changes in
  market price of those securities but are included with the net realized and
  unrealized gain or loss on investments.

C. Forward Foreign Currency Contracts
  The Fund enters into forward foreign currency contracts (contracts) for the
  purchase or sale of a specific foreign currency at a fixed price on a future
  date as a hedge or cross-hedge against either specific investment
  transactions (settlement hedges) or portfolio positions (portfolio hedges).
  All contracts are marked to market daily at the applicable exchange rates,
  and any resulting unrealized gains or losses are recorded in the Fund's
  financial statements. The Fund records realized gains and losses at the time
  a portfolio hedge is offset by entry into a


22

  closing transaction or extinguished by delivery of the currency. Risks may
  arise upon entering into these contracts from the potential inability of
  counterparties to meet the terms of the contract and from unanticipated
  movements in the value of foreign currencies relative to the U.S. dollar. As
  of November 30, 1997, the Fund had no outstanding settlement or portfolio
  hedges.

D. Taxes
  It is the Fund's policy to comply with the requirements of the Internal
  Revenue Code applicable to regulated investment companies and to distribute
  all of its taxable income and net realized capital gains, if any, to its
  shareholders. Therefore, no federal income tax provision is required. In
  addition to the requirements of the Internal Revenue Code, the Fund may also
  be required to pay local taxes on net realized capital gains in certain
  countries. The required capital gains taxes, if any, are determined in
  accordance with local tax laws. In determining daily net asset value, the
  Fund estimates the reserve for capital gains taxes, if any, associated with
  net unrealized gains on certain portfolio securities. The estimated reserve
  for capital gains taxes, if any, is based on the holding periods of such
  securities and the related tax rates, tax loss carryforward (if applicable)
  and other such factors. During the year ended November 30, 1997, the Fund
  paid $44,588 in capital gains taxes on the sale of certain foreign
  securities.

  The characterization of distributions to shareholders for financial
  reporting purposes is determined in accordance with federal income tax
  rules. Therefore, the source of the Fund's distributions may be shown in the
  accompanying financial statements as either from or in excess of net
  investment income or net realized gain on investment transactions, or from
  paid-in capital, depending on the type of book/tax differences that may
  exist.

  At November 30, 1997, the Fund reclassified $1,105,477 from accumulated
  undistributed net realized gain on investments and foreign currency
  transactions to accumulated net investment loss. The reclassification has no
  impact on the net asset value of the Fund and is designed to present the
  Fund's capital accounts on a tax basis.

  In order to comply with federal income tax regulations, the Fund has
  designated $3,212,225 as a capital gain dividend for the purposes of the
  dividend paid deduction.


                                                                              23

 Pioneer Emerging Markets Fund
 NOTES TO FINANCIAL STATEMENTS 11/30/97                  (continued)

E. Fund Shares
  The Fund records sales and repurchases of its shares on trade date. Net
  losses, if any, as a result of cancellations are absorbed by Pioneer Funds
  Distributor, Inc. (PFD), the principal underwriter for the Fund and an
  indirect subsidiary of The Pioneer Group, Inc. (PGI). PFD earned $72,117 in
  underwriting commissions on the sale of fund shares during the year ended
  November 30, 1997.

F. Class Allocations
  Distribution fees are calculated based on the average daily net asset value
  attributable to Class A, Class B and Class C shares of the Fund,
  respectively. Shareholders of each class share all expenses and fees paid to
  the transfer agent, Pioneering Services Corporation (PSC), for their
  services, which are allocated based on the number of accounts in each class
  and the ratable allocation of related out-of-pocket expense (see Note 3).
  Income, common expenses and realized and unrealized gains and losses are
  calculated at the Fund level and allocated daily to each class of shares
  based on the respective percentage of adjusted net assets at the beginning
  of the day.

  Distributions to shareholders are recorded as of the ex-dividend date.
  Distributions paid by the Fund with respect to each class of shares are
  calculated in the same manner, at the same time, and in the same amount,
  except that Class A, Class B and Class C shares can bear different transfer
  agent and distribution fees.


2. Management Agreement
Pioneering Management Corporation (PMC), the Fund's investment adviser, manages
the Fund's portfolio and is a wholly owned subsidiary of PGI. Management fees
are calculated daily at the annual rate of 1.25% of the Fund's average daily
net assets.

PMC has agreed not to impose a portion of its management fee and to assume
other operating expenses of the Fund to the extent necessary to limit Class A
expenses to 2.25% of the average daily net assets attributable to Class A
shares; the portion of the Fund-wide expenses attributable to Class B and Class
C shares will be reduced only to the extent that such expenses are reduced for
Class A shares. PMC's agreement is voluntary and temporary and may be revised
or terminated at any time.

In addition, under the management agreement, certain other services and costs,
including accounting, regulatory reporting and insurance premiums,


24

 Pioneer Emerging Markets Fund


are paid by the Fund. At November 30, 1997, $174,169 was payable to PMC related
to management fees and certain other services.


3. Transfer Agent
PSC, a wholly owned subsidiary of PGI, provides substantially all transfer
agent and shareholder services to the Fund at negotiated rates. Included in due
to affiliates is $89,651 in transfer agent fees payable to PSC at November 30,
1997.


4. Distribution Plans
The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the Fund's average daily net assets in reimbursement of
its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to each
class of shares. The fee consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class
C shares. Included in due to affiliates is $108,537 in distribution fees
payable to PFD at November 30, 1997.

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within one year of
purchase. Class B shares that are redeemed within six years of purchase are
subject to a CDSC at declining rates beginning at 4.0%, based on the lower of
cost or market value of shares being redeemed. Redemptions of Class C shares
within one year of purchase are subject to a CDSC of 1.00%. Proceeds from the
CDSC are paid to PFD. For the year ended November 30, 1997, CDSCs in the amount
of $145,123 were paid to PFD.


5. Expense Offsets
The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the year ended November 30, 1997,
the Fund's expenses were reduced by $61,858 under such arrangements.


6. Other
During the year ended November 30, 1996, PMC reimbursed the Fund $14,845 in
connection with costs incurred on certain portfolio transactions.


                                                                              25

 RETIREMENT PLANS FROM PIONEER

Pioneer has a long history of helping people work toward their retirement
goals, offering plans suited to the individual investor and businesses of all
sizes. For more information on Pioneer retirement plans, contact your
investment professional, or call Pioneer at 1-800-622-0176.


Individual Retirement Account (IRA)
An IRA is a tax-favored account that allows anyone under age 701/2 with earned
income to contribute up to $2,000 annually. Spouses may contribute up to $2,000
annually into a separate IRA, for a total of $4,000 per year for a married
couple. Earnings are tax-deferred, and contributions may be tax-deductible.


Roth IRA
The Roth IRA came about as part of the Taxpayer Relief Act of 1997 and is
available to investors in 1998. Contributions, up to $2,000 a year, are not
tax-deductible, but earnings are tax-free for qualified withdrawals.


401(k) Plan
The traditional 401(k) plan allows employees to make pre-tax contributions
through payroll deduction, up to $9,500 per year or 25% of pay, whichever is
less. Employers may contribute.



SIMPLE (Savings Incentive Match PLan for Employees)
401(k) or IRA Plan
Businesses with 100 or fewer eligible employees can establish either plan; both
resemble the traditional 401(k), but with less testing and lower administration
costs. Employees can make pre-tax contributions of up to $6,000 per year, and
an employer contribution is required.


Most retirement plan withdrawals must meet specific conditions to avoid 
penalties.

403(b) Plan
Also known as a Tax-Sheltered Account (TSA), a 403(b) plan is available only to
employees of public schools, not-for-profit hospitals and other tax-exempt
organizations. A 403(b) plan lets employees set aside a portion of their
salary, before taxes, through payroll deduction.


Simplified Employee Pension Plan (SEP)
SEPs let self-employed people and small-business owners make tax-deductible
contributions of up to 15% of their income. Generally, employers must
contribute the same percentage of pay for themselves and any eligible
employees; contributions are made directly to employees' IRAs. SEPs are easy to
administer and can be an especially good choice for firms with few or no
employees.


Profit Sharing Plan
Profit sharing plans offer companies considerable flexibility, allowing them to
decide each year whether a contribution will be made and how much, up to 15% of
each participant's pay. These plans can include provisions for loans and
vesting schedules.


Age-Weighted Profit Sharing Plan
Like traditional profit sharing plans, employer contributions are flexible, but
age-weighted plans allocate contributions based on both age and salary. Age-
weighted plans are designed for employers who want to maximize their own
contributions while keeping contributions to employees affordable.


Money Purchase Pension Plan (MPP)
Money purchase plans are similar to profit-sharing plans, but allow for higher
annual contributions--up to 25% of pay. MPPs aren't as flexible as profit
sharing plans; a fixed percentage of pay must be contributed each year,
determined when the plan is established. Businesses often set up both MPPs and
profit sharing plans.


Most retirement plan withdrawals must meet specific conditions to avoid
penalties.
