Wang Yongchun, a vice president at state-owned China National Petroleum Corporation, is being investigated by China’s top anti-corruption authority, The Wall Street Journal reported, citing a government agency. The Ministry of Supervision said on Monday it was probing Wang for “severe disciplinary violations”. It didn’t disclose more details, but such phrasing is typically used by Chinese officials when investigating cases of alleged corruption. The move is the latest investigation into high-ranking officials at Chinese government agencies and state-owned enterprises.
