HONG KONG (AP) — Chinese authorities are investigating three more top officials at the country’s biggest oil company, state-owned CNPC.
China National Petroleum Corp.’s listed subsidiary, PetroChina, said Tuesday that two vice-presidents and its chief geologist are being investigated by “relevant” authorities but did not say why.
The company said the three have resigned for personal reasons.
Tuesday’s announcement comes a day after the Chinese government said a CNPC executive was being investigated for unspecified “severe violations of discipline,” often shorthand for corruption.
Earlier this month, a general manager at state-owned phone company China Mobile was detained. A government announcement said he faced an investigation of suspected discipline violations.
China’s new leader, Xi Jinping, has pledged to crack down on corruption.
