The Communist Party of China (CPC) says in its revised Constitution that the Party must "make comprehensive efforts" to ensure that "the fight against corruption keeps going", according to a resolution approved by the 19th CPC National Congress on Tuesday.

Since its 18th National Congress, the Party has made steady progress in exercising full and rigorous governance over the Party, taken all-around measures to explore the strengthening of Party building, and gained abundant successful experience and achieved major outcomes, which must be included into the Party Constitution in a timely manner and therefore become the common will and rule of the whole Party.

The Party must firmly exercise self-supervision and practice strict self-governance in every respect, the revised Constitution says.

Opening the congress on Oct. 18, Xi Jinping called corruption "the greatest threat" the Party faces.

The Party will work for the adoption of national anti-corruption legislation and create a corruption reporting platform that covers both disciplinary inspection commissions and supervision agencies, he said.

Disciplinary authorities have investigated 440 officials at or above provincial or corps level for corruption over the past five years, who included 43 members and alternate members of the CPC Central Committee, as well as nine members of the Central Commission for Discipline Inspection (CCDI), said Yang Xiaodu, deputy secretary of the CCDI, at a press conference on the sidelines of the 19th CPC National Congress.
