27 June, 2007, Beijing - PetroChina Company Limited ("PetroChina", SEHK stock code 0857; NYSE symbol PTR) obtained an attestation from PricewaterhouseCoopers, regarding the management's assessment of its internal control over financial reporting. According to the auditor's report issued on 10 May, 2007, the management's assessment that PetroChina's internal control over financial reporting was effective as of 31 December, 2006, is fairly stated in all material respects. PetroChina, as a US-listed company, is one of the first Chinese companies which have obtained such attestation in accordance with Section 404 of the Sarbanes-Oxley Act.

Establishing and maintaining effective internal control over financial reporting is not merely a product of regulatory compliance. The initiative is also critical to PetroChina's management and development. To enhance the effectiveness of PetroChina internal control over financial reporting, PetroChina's Board of Directors (the "Board") initiated certain internal control measures, and set out plans and guidelines to improve the management standard in August 2003. In the past three years, following the direction of the Board and the management team, PetroChina's management professionals have prepared an internal control manual, "Management's Manual of Internal Controls". The manual was written based on the internal control framework established by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), as well as PetroChina's real and specific conditions. The manual, which provides guidance on setting up internal control organization and network, helps PetroChina optimize the assessment and execution of internal controls and develop a systematic internal control environment that covered all aspects of PetroChina's management and operations. In 2006, the internal control system was launched successfully. With continuous and relentless efforts in improving and strengthening the execution by all staff, the internal control system has been well-implemented.

The launch and implementation of the internal control system is of great significance to PetroChina's of management and operation. Through continuous development of the internal control facilities, a proactive risk control system has been structurally established and practiced in operation. The effective internal control system helps PetroChina further strengthen its operation in a systematic, regulated and procedural manner.
