BEIJING - China's anti-corruption efforts have purified the market and boosted economic growth, officials said Friday at a press conference.

"The crackdown on corruption has eliminated market operation obstacles and ensured the decisive role of market, which are conducive to a sustainable and sound economy," said Chen Xiaojiang, director of the publicity department under the Communist Party of China (CPC) Central Commission for Discipline Inspection (CCDI).

The fight against corruption has never, and will not, influence the ruling foundation, said Chen, adding such efforts will consolidate the CPC's governance and help secure public trust in the Party.

The view was backed by Liu Jianchao, director of international cooperation bureau of the CCDI.

"Under the backdrop of the counter corruption drive, which has brought about clean governance, foreign investors have more confidence in China," said Liu, denying reports that the fight has dampened foreign investment.
