Withdrawal of Post-Effective Amendment on Form S-8
Dear Commissioners
Pursuant to Rule 477 (a), the Registrant respectfully requests that the
Post-Effective Amendment on Form S-8 filed on August 28, 2000, be withdrawn.
This filing was inadvertently filed by our filing agent RR Donnelley Financial
without II pages 2-6. The Registrant desires to withdraw Post-Effective
Amendment on Form S-8 and intends to immediately file the Post-Effective
Amendment with the complete II section pages 1-6.
If you have any questions or comments regarding this filing, please call me
Zhuang ZhenKuo at Clifford Chance (Hong Kong) on (852) 2825 8841 or Mary Vander
Mast at RR Donnelley Financial Hong Kong on (852) 2522 3803.
Very truly yours
