China's fight against deeply ingrained corruption will never end, the top official in charge of tackling graft said before a meeting intended to clean up business in the world's second-largest economy.

Since President Xi Jinping launched his high-profile campaign against corruption after assuming office last year, several senior officials, including powerful former domestic security chief Zhou Yongkang, have been removed from their posts and investigated.

"All these efforts have gained the support of the general public," said Wang Qishan, who heads the ruling Communist Party's Central Commission for Discipline Inspection.
