A Chinese court has sentenced a former senior executive of a state oil company to 20 years in prison after finding him guilty of corruption.

The sentencing of Wang Yongchun, former deputy general manager of China National Petroleum Corp., came a day after the company's former chairman, Jiang Jiemin, was given 16 years' imprisonment for corruption.

The Xiangyang Intermediate People's Court in central China said Wang had received 49 million yuan ($7.9 million) in bribes between 2000 and 2013 and failed to explain the source of another 42 million yuan.

It said Wang — at Jiang's direction — provided assistance to others, causing huge losses to the state.

China's oil industry has been targeted in a sweeping anti-graft campaign that has toppled many high-ranking officials of state companies.
