China’s corruption watchdog recently expelled another high-level regional leader from the Communist Party and removed him from posts for suspicion of corruption.

According to an official statement released on Monday, Qian Yin'an, former Communist Party secretary of northwestern China’s Shaanxi province, “seriously violated” Communist Party discipline by taking advantage of his official positions to acquire personal gains. Qian “refused to accept the Communist Party’s education and rescue,” and has “no political awareness at all,” said the statement.

Particularly, the statement said, the official frequently participated in gambling activities — cards and mahjong — with owners of private enterprises. In such cases, as people familiar with China's officialdom say, businessmen would intentionally lose money to officials to bribe them.

The size of Qian’s alleged bribery is unknown. His corruption case is still under investigation.
