Zhu was well known for his efforts to fight official corruption, but was not able to contain official corruption in his term. Following the 18th CCP National Congress in 2012, one of Zhu's proteges, Wang Qishan, became the head of China's Central Commission for Discipline Inspection, the Communist Party's main organ in charge of investigating internal corruption. Zhu publicly supported Xi Jinping's anti-corruption campaign in which Wang played a major role.
