Another senior figure at Chinese state-backed chemical giant Sinochem Group has fallen from grace.

Du Keping, the former deputy general manager of Sinochem, has been expelled from the Communist Party of China for breaking party rules and regulations, the Central Commission for Discipline Inspection (CCDI) announced on its website Tuesday.

Du was put under investigation in December for suspicion of “serious violation of laws and discipline,” a euphemism for corruption.

The latest statement said he was found to have resisted investigation and violated “the Eight-Point Regulations” — a series of rules against the abuse of official privileges introduced in 2012 — among other accusations. The CCDI also said Du was suspected of serious crimes related to his job, and that prosecutors were taking over the case.

Du is the second high-ranking figure from Sinochem to face charges in recent months. His superior, former Sinochem general manager Cai Xiyou, was sentenced to 12 years in jail and a 3 million yuan fine for corruption in December. 

Du joined Sinochem in 2006 but lost his job as the deputy chief in 2017 before the investigation into his misconduct was announced.
