State-backed oil giant PetroChina (PTR.NYSE, 0857.HKG, 601857.SHA) on Tuesday said three high-level managers had resigned as they are being probed by Chinese authorities, Bloomberg reported. The managers are “currently under investigation by relevant PRC authorities,” the company said in a statement. The three are Li Hualin, chairman of Kunlun Energy (0135.HKG), a PetroChina unit; the company’s vice president Ran Xinquan; and Wang Daofu, chief geologist. The probes at PetroChina come amid a wider crackdown by China’s top leadership against official corruption.
