                             CONNECTED TRANSACTION
--------------------------------------------------------------------------------
Sinopec Corp. and Sinopec Group Company have entered into the Arrangement with
Sinopec Finance on 31 March 2006, under which Sinopec Corp. and Sinopec Group
Company will make a cash injection of RMB1,602.3 million and RMB897.7 million,
respectively, into Sinopec Finance and Sinopec Finance will capitalise RMB1
billion from its statutory reserve and undistributed profits reserve into
registered capital such that the total registered capital of Sinopec Finance
will increase from RMB2.5 billion (including US$60 million) to RMB6 billion.
Upon completion of the injection, Sinopec Corp.'s equity interest in Sinopec
Finance will increase from 38.22 percent to 49 percent. Sinopec Corp. intends
to finance the Capital Injection by Sinopec Corp.'s internal resources.

The directors (including independent non-executive directors) of Sinopec Corp.
consider that the Arrangement and the terms thereof are on normal commercial
terms, are fair and reasonable and that the transactions contemplated
thereunder are in the interests of the shareholders of Sinopec Corp. as a
whole.

Sinopec Group Company is the holder of approximately 71.2 percent of the total
issued capital of Sinopec Corp. As Sinopec Finance is also a subsidiary of
Sinopec Group Company, Sinopec Finance is an associate of Sinopec Group
Company and a connected person to Sinopec Corp. under the Listing Rules.
Accordingly, the Capital Injection constitutes a connected transaction for
Sinopec Corp. under Rule 14A.13(1)(a) of the Listing Rules. As each of the
percentage ratios in respect of the Capital Injection falls below 2.5 percent
of the size tests (other than the profits test), the Capital Injection is
exempted from the independent shareholders' approval requirement under Rule
14A.32 of the Listing Rules. Sinopec Corp. is only obliged to comply with the
reporting and announcement requirements under Chapter 14A of the Listing Rules
in respect of the Capital Injection.
-------------------------------------------------------------------------------

The Capital Injection Arrangement

The board of directors (the "Board") of China Petroleum & Chemical Corporation
("Sinopec Corp.") announces that on 31 March 2006, Sinopec Corp. and China
Petrochemical Corporation ("Sinopec Group Company") have entered into an
arrangement (the "Arrangement") with Sinopec Finance Co., Ltd ("Sinopec
Finance") under which Sinopec Corp. and Sinopec Group Company will make a cash
injection of RMB1,602.3 million (the "Capital Injection") and RMB897.7,
respectively, into Sinopec Finance such that the total registered capital of
Sinopec Finance after completion of the injection will increase from RMB2.5
billion (including US$60 million) to RMB6 billion.

Pursuant to the Arrangement, Sinopec Finance will capitalize RMB1 billion from
its statutory reserve and undistributed profits reserves into registered
capital and the equity interest so increased will be allocated to Sinopec
Corp. and Sinopec Group Company in the proportion of 38.22% and 61.78%,
respectively.

Upon completion, Sinopec Corp.'s equity interest in Sinopec Finance will
increase from 38.22 percent to 49 percent, while Sinopec Group Company's
interest in the equity interest of Sinopec Finance will be diluted from 61.78
percent to 51 percent. Under present circumstances, Sinopec Corp. will not
consolidate the results of Sinopec Finance into its financial statements.
Sinopec Finance will constitute an associated company of Sinopec Corp. and
will be accounted for under the equity method.

Sinopec Corp. intends to finance the Capital Injection by internal resources of
Sinopec Corp.





Completion of the Capital Injection is expected to take place within 10 days
from the grant of the approval by the China Banking Regulatory Commission or
such other date as Sinopec Corp. and Sinopec Group Company may agree.

Consideration

The consideration payable in respect of the Capital Injection was determined
after arm's length negotiation between Sinopec Corp., Sinopec Group Company
and Sinopec Finance. The consideration payable by Sinopec Corp. and Sinopec
Group Company represents the nominal value of the registered capital increased
of Sinopec Finance.

Reasons for the proposed Capital Injection and benefits to Sinopec Corp.

Due to additional need for capital by Sinopec Finance for business expansion,
Sinopec Finance has proposed to its holders of equity interest to make
additional capital injection.

Sinopec Corp. believes that its increased equity interest in Sinopec Finance
from 38.22 percent to 49 percent will enable it to obtain better return for
its investment in Sinopec Finance. Sinopec Corp. also believes that the
Capital Injection will increase the capital base of Sinopec Finance and
therefore, reducing the costs of financing and enabling it to provide more
comprehensive financial management services to entities with the Sinopec
Group, including Sinopec Corp.

Relationship between Sinopec Corp., Sinopec Group Company and Sinopec Finance

Sinopec Group Company is the holder of approximately 71.2 percent of the total
issued capital of Sinopec Corp. As Sinopec Finance is also a subsidiary of
Sinopec Group Company, Sinopec Finance is an associate of Sinopec Group
Company and a connected person to Sinopec Corp. under the Listing Rules. Under
rule 14A.13(1)(a) of the Listing Rules, the proposed Capital Injection will
constitute a connected transaction of Sinopec Corp. As the amount of Capital
Injection is less than 2.5 of the percentage ratios under the Listing Rules
(other than the profits test), the transaction would fall under the exception
under rules 14A.32 of the Listing Rules and Sinopec Corp. is only required to
comply with the reporting and announcement requirements thereunder. Under rule
14A.32 of the Listing Rules, independent shareholders' approval is not
required.
