China must win its battle against corruption or face being erased by history, its new top graft buster said in an editorial on Saturday, underscoring the ruling Communist Party's focus on eliminating corrupt behavior.

Zhao Leji, appointed to the new seven-member Politburo Standing Committee last month and tasked to lead President Xi Jinping's signature war on corruption, wrote in the state-run People's Daily that failure would lead to the party's downfall.

"If our control of the party is not strong and party governance is not strict, then the party won't be able to avoid being erased by history and the historic task the party carries will not be able to be fulfilled," Zhao wrote.
