Wang Qishan (center), chief of the Central Commission for Discipline Inspection of the Communist Party of China, speaks during the commission's Fourth Plenary Session in Beijing on October 25.

Wang warned that the Party is facing a severe and complicated situation in curbing corruption.

"Any corrupt officials who go back to their old ways will pay the price," Wang said. "We will keep pressing the anti-graft campaign, treating sick trees and rooting up the rotten ones."

He added that the campaign will curb current corruption, clear out its sources and establish an effective system to prevent it.
