The State-Owned Assets Supervision and Administration Commission (SASAC) said on Tuesday that PetroChina vice president Ran Xinquan, PetroChina chief geologist Wang Daofu and CNPC group deputy general manager Li Hualin were all under investigation. Their accusations, however, were not disclosed.
This follows a notice on Monday by the Ministry of Supervision stating that CNPC vice president Wang Yonchun had been placed under investigation for disciplinary breaches.
