To the Shareholders

Dear Sirs


              PROPOSED ISSUE OF DOMESTIC CORPORATE BONDS IN THE PRC
INTRODUCTION

     On 10 June 2008, the Board resolved to seek shareholders' approval for the
proposed issue of the Domestic Corporate Bonds in the PRC at the EGM to be
convened on Thursday, 31 July 2008. This circular is to provide you with
information regarding the proposed issue of the Domestic Corporate Bonds in
order to allow you to make an informed decision on voting in respect of the
resolution to be proposed at the EGM.

PROPOSED ISSUE OF DOMESTIC CORPORATE BONDS IN THE PRC

1. BACKGROUND

     During the "Eleventh Five-Year Plan", the Company has increased capital
needs due to factors including relatively large amount of capital expenditure on
investment in projects, significant increase in special levy on domestic crude
oil sales as a result of soaring crude oil prices and the under-pricing of
domestic refined product prices. To satisfy the operational needs of the
Company, further improve its debt structure, reduce the financing costs and
supplement the working capital of the Company, the Board announced that on 10
June 2008, it resolved to submit to Shareholders for consideration and approval
the proposed issue of the Domestic Corporate Bonds with an aggregate principal
amount of not more than RMB60 billion in one or more tranches at the EGM to be
held on 31 July 2008. The Domestic Corporate Bonds are not convertible or
exchangeable into Shares.
