The mainland's top anti-corruption official, Wang Qishan, has urged all central government departments and state-owned companies and financial institutions to strengthen efforts to combat graft, signalling his dissatisfaction with their current campaigns.
Wang has chaired four meetings on anti-corruption with the top leaders of these departments and companies in the past week, the Central Commission for Discipline Inspection said on its website yesterday.
Wang said that they must protect the Communist Party's image and seek to increase rather than decrease its credibility.
"Don't forget your party position and responsibilities," Wang said, urging them to do more than "pay attention to business".
He also pledged to punish officials who failed to closely supervise and control the conduct of their staff.
Anti-corruption officials working within government departments and state companies should only concentrate on this work and not be sidetracked by other duties, Wang said.
"[We must] focus on investigating and punishing those who act without restraint, those who are the source of strong complaints from the public and who sit in important jobs waiting for promotion," Wang said. The effort was needed to create an atmosphere of "shock and awe", he said.
Dozens of senior officials have been jailed or investigated since President Xi Jinping launched his anti-corruption campaign in 2012.
Song Lin , the former chairman of the state-owned conglomerate China Resources, was placed under investigation last month.
Former anti-corruption watchdog official Wei Jian, who was mainly responsible for investigating the affairs of financial institutions, is also the subject of an investigation, the commission said on Friday.
