Former Yunnan party chief, Shanxi pair, latest to be probed for graft
Two more cadres from troubled Shanxi party also face corruption investigations
A former party chief of Yunnan province and two high-ranking Shanxi officials are under investigation for corruption - the latest targets of an anti-graft campaign launched by President Xi Jinping.
The Central Commission for Discipline Inspection said Bai Enpei, 68, Yunnan party secretary from 2001 to 2011, was suspected of "having seriously violated discipline and law", a term that usually refers to graft.
Before governing Yunnan, Bai spent 20 years in Shaanxi and Inner Mongolia, and was Qinghai governor and party boss in the late 1990s.
He was nominated as deputy head of the environment and resource protection committee of the National People's Congress in August 2011.
Bai was implicated in the case of Liu Han, a Sichuan mining tycoon with links to disgraced former security tsar Zhou Yongkang . Liu was sentenced to death in May for leading a mafia-style gang.
The commission also announced that Bai Yun, a member of the Shanxi party leadership's standing committee and director of its United Front Work Department, was being investigated for the same offence.
