NANCHANG -?Wang Tianpu, former general manager of oil giant China Petroleum and Chemical Corporation (Sinopec Group), was sentenced Tuesday to 15 and a half years in prison for graft.

The sentence was handed down by the Nanchang City Intermediate People's Court in east China's Jiangxi Province.

The court also imposed a fine of 3.2 million yuan (around 468,300 U.S. dollars) on Wang and ordered all his illicit gains to be confiscated.

The court found that from 2003 to 2014, Wang took advantage of his various positions to help others with business operations, project undertaking and job placement. He asked for and illegally accepted money and property worth over 33.4 million yuan and illegally possessed state-owned assets worth almost 800,000 yuan, according to the court.

The court showed leniency, taking into consideration his confession, remorse and the fact that he voluntarily turned over all his proceeds.
