BEIJING, Oct. 15 (Xinhua) -- China's fight against corruption has achieved an overwhelming victory and this momentum has been consolidated across the board, but the situation is still grave and complex, a spokesperson for the 20th National Congress of the Communist Party of China (CPC) said here on Saturday.

Addressing a press conference a day ahead of the congress, Sun Yeli said since the 18th CPC National Congress, the Party, under the strong leadership of the CPC Central Committee with Comrade Xi Jinping at its core, has managed to blaze a trail of fighting corruption by making use of its institutional strengths and the rule of law.

Between November 2012 and June 2022, discipline inspection and supervision bodies across the country had investigated over 4.5 million cases of corruption, and more than 4.4 million people were punished, Sun said.

Meanwhile, efforts have been made to develop the sound systems of intra-Party regulations and anti-graft laws, and to strengthen education on clean governance.

Calling the fight against corruption a major political struggle that the Party cannot and must not lose, Sun said the country will next focus on key areas and sectors, take firm action to "take out tigers," "swat flies," and "hunt down foxes," in order to win the critical battle against corruption.
