Chinese state media say a top official who led the country's biggest petroleum company and later was assigned to oversee state-owned firms has been convicted of corruption and sentenced to 16 years in prison.

State broadcaster CCTV said Jiang Jiemin, former chairman of the state-run China National Petroleum Corp., told the court that he would not appeal Monday's verdict.

Jiang was tried in April on charges of corruption and abuse of power.

The state oil company has been a target of a sweeping anti-corruption campaign that has netted top officials since Chinese President Xi Jinping came into power in late 2012.

In 2013 Jiang was appointed to the Cabinet body that oversees China's biggest state-owned firms. He was fired from the post later that year after he came under investigation.
