ANNOUNCEMENT

This announcement is jointly issued by the boards of directors of Beijing 
Yanhua Petrochemical Company Limited ("Beijing Yanhua"), Shanghai 
Petrochemical Company Limited ("Shanghai Petrochemical"), Yizheng 
Chemical Fibre Company Limited ("Yizheng Chemical"), and Zhenhai Refining 
& Chemical Company Limited ("Zhenhai Refining") on a reorganisation of 
their ultimate holding company, China Petrochemical Corporation ("PPC"). 
The reorganization was completed on 25 February 2000. Upon completion of 
such reorganization, China Petroleum & Chemical Corporation ("Sinopec"), a 
wholly owned subsidiary of CPC, has become the controlling shareholder (as 
defined in the Rules Governing the Listing of Securities on the Stock 
Exchange ("Listing Rules")) of each of Beijing Yanhua, Shanghai 
Petrochemical, Yizheng Chemical, and Zhenhai Refining. Applications will 
be made to the Executive (as defined in the Hong Kong Code on Takeovers 
and Mergers ("Takeovers Code")) for waivers of any general offer 
obligations.

Brief information on the reorganization

The board of directors of each of Beijing Yanhua, Shanghai Petrochemical, 
Yizheng Chemical and Zhenhai Refining wishes to announce that CPC has 
undergone a reorganization. Pursuant to the reorganization, Sinopec was 
established on 25 February 2000 as a joint stock limited company in the 
People's Republic of China ("PRC"), which is wholly owned by CPC. With 
effect from that date, CPC either by itself or through its wholly owned 
subsidiaries transferred to Sinopec certain assets and liabilities 
including, without limitation to, the following:-

1.      2,362,000,000 State-owned shares of RMB1.00 each in the share 
capital of Beijing Yanhua representing 70% of the entire issued share 
capital of Beijing Yanhua;

2.      4,000,000,000 State-owned shares of RMB1.00 each in the share 
capital of Shanghai Petrochemical representing 55.56% of the entire issued 
share capital of Shanghai Petrochemical;

3.      1,680,000,000 State-owned shares of RMB1.00 each in the share 
capital of Yizheng Chemical representing 42% of the entire issued share 
capital of Yizheng Chemical; and

4.      1,800,000,000 State-owned shares of RMB1.00 each in the share 
capital of Zhenhai Refining, representing 71.3% of the entire issued share 
capital of Zhenhai Refining.

(For the following diagrams set out the corporate structure of CPC 
immediately before and after the reorganization to the extent relating to 
Beijing Yanhua, Shanghai Petrochemical, Yizheng Chemical and Zhenhai 
Refining, please refer to the press announcement today)

By virtue of Rule 26.1(a) of the Takeovers Code, mandatory offer 
obligations might (unless waived) be triggered upon the completion of the 
reorganization. Note 6(b)(i) of the Notes to Rule 26.1 of the Takeovers 
Code provides that the Executive would normally grant the acquirer (in 
the present case, Sinopec) of 35% or more of the voting rights of a 
company a waiver from a general offer obligation if the acquirer is a 
member of a group of companies comprising a company and its subsidiaries 
and the acquirer has acquired the voting rights from another member of 
such group of companies.

On such basis, applications will be submitted to the Executive for waivers 
of the obligations of Sinopec to make general offers to the H shareholders 
of each of Beijing Yanhua, Shanghai Petrochemical, Yizheng Chemical and 
Zhenhai Refining on the basis that the ultimate controlling shareholder 
(as defined in the Listing Rules) of these companies before and after the 
reorganization is still CPC and that CPC, Sinopec, Beijing Yanhua, 
Shanghai Petrochemical, Yizheng Chemical and Zhenhai Refining are within 
the same group of companies.

Connected Transactions and waivers granted by the Stock Exchange

Prior to the reorganization, each of Beijing Yanhua, Shanghai 
Petrochemical, Yizheng Chemical and Zhenhai Refining has obtained certain 
waivers from the Stock Exchange from strict compliance with certain 
ongoing disclosure and shareholders' approval requirements under the 
Listing Rules in relation to certain connected transactions. As a result 
of the reorganization, such waivers may need to be modified. In addition, 
certain transactions which were not connected transactions before the 
reorganization may become connected transactions for Beijing Yanhua, 
Shanghai Petrochemical, Yizheng Chemical or Zhenhai Refining following 
the reorganization. CPC, Sinopec, Beijing Yanhua, Shanghai Petrochemical, 
Yizheng Chemical and Zhenhai Refining are in discussion on the nature and 
the anticipated amounts of such connected transactions and, if necessary, 
will apply to the Stock Exchange for modifying the existing waivers or 
for new waivers in relation to such connected transactions and, if 
necessary, will apply to the Stock Exchange for modifying the existing 
waivers or for new waivers in relation to such connected transactions. 
Any connected transactions will be conducted in compliance with the 
disclosure and shareholders' approval requirements (where necessary) of 
the Listing Rules. Further particulars of such connected transactions and 
the waivers will be announced by each of Beijing Yanhua, Shanghai 
Petrochemical, Yizheng Chemical and Zhenhai Refining separately.
