BEIJING - Jiang Jiemin, head of a Cabinet commission that supervises major state-owned enterprises, has been removed from office because of suspected serious disciplinary violations, authorities said Tuesday.

The decision comes two days after officials confirmed he was being investigated.

Jiang was head of the State-owned Assets Supervision and Administration Commission (SASAC) and deputy secretary of the SASAC committee of the Communist Party of China (CPC).

Xinhua learnt of Jiang's dismissal from the Organization Department of the CPC Central Committee on Tuesday.

The CPC Central Commission for Discipline Inspection and the Ministry of Supervision said on Sunday that Jiang is under investigation for such violations.

It is the first time that a full member of the 18th Central Committee of the CPC became the subject of a corruption probe as the Party's upgraded war on corruption since late last year's national congress has resulted in the fall of a number of corrupt officials.

Previously, Li Chuncheng, then deputy Party chief in Sichuan province and Wang Yongchun, then deputy general manager of the China National Petroleum Corporation, were also sacked for "serious disciplinary violations."

Xi Jinping, general secretary of the CPC Central Committee, has called for a crackdown on corruption, vowing to target both "tigers" and "flies," or high-ranking and low-level officials.

The CPC's stepped-up efforts in fighting corruption and removing undesirable work styles among officials have demonstrated the Party's resolution in exercising strict self-discipline, according to political analysts.
