The discipline watchdog of the Communist Party of China (CPC) Tuesday said "the task of anti-corruption remains arduous," and new anti-graft achievements should be scored ahead of the Party's 18th National Congress.

A communique released Tuesday at the end of a three-day plenary session of the CPC's Central Commission for Discipline Inspection (CCDI) pointed out that "the anti-graft situation is still severe and the anti-corruption task is still arduous."

The communique said China's current fight against corruption comes while the international environment is severe and complicated, and the domestic economic system and social structure are undergoing significant changes.

The war on corruption has scored evident achievements, but prominent problems still exist, and although anti-corruption efforts have been intensified, corruption still occurs, it said.

The general situation also features people's higher expectations for anti-corruption achievements coexisting with the fact that the corruption phenomena cannot be eradicated in the short term, it said.

The plenary session of the CPC's discipline watchdog stressed that to better do the anti-corruption work is of great significance in 2012, in which the 18th National Congress of the CPC will be held.

The plenary session held that the long-term and fundamental works in the fight against corruption should be carried out this year, and the problems relating to anti-corruption should be resolved.
