Jiang’s is the latest in a series of high-profile officials who have been placed under investigation on corruption charges.

Till March this year, Jiang was the head of CNPC, which now has a number of top officials under investigations.
Last week, four senior executives of CNPC, which is Asia’s largest oil and gas producer, were removed for "serious violations of discipline".
The CNPC's Communist Party of China (CPC) committee said the four were relieved of Party-related posts and corporate administrative posts, and their job titles with the CNPC's joint-stock and listed subsidiaries will be removed following due procedures.
In fact, it was the State-owned Assets Supervision and Administration Commission on which had confirmed that the four were under investigation.
China's new leadership has widened its crackdown on corruption, netting a number of high-ranking and low-ranking officials over suspected legal and disciplinary violations, state-run Xinhua news agency reported.
