The Political Bureau of the Communist Party of China (CPC) Central Committee has warned all CPC members that "the phenomenon of corruption is still quite serious".

Hu Jintao, general secretary of the CPC Central Committee and also China's President, presided over a Politburo meeting here on Monday, which pledged to continue the major task of fighting corruption and achieving a clean governance, according to a statement from the CPC.

At the meeting, the participants heard a report on the work of the CPC Central Committee for Discipline Inspection (CCDI) in 2006 and studied anti-corruption work in 2007.

It was agreed that the CCDI would hold its seventh plenary meeting in January.

The Politburo urged the whole Party to remain unified in thinking, to have a deep understanding of the long-term, complicated and difficult nature of the efforts to bring about clean governance and fight corruption.

The anti-corruption campaign should be integrated into the country's economic, political and cultural drives and the building of the Party, it said.

Following Shanghai's Party chief Chen Liangyu's dismissal for involvement in corruption in October, a provincial Party official Du Shicheng, in east China's Shandong Province, was put under investigation by the CCDI on Sunday for "violating Party discipline".
