BEIJING, Sept. 23 -- Chinese top discipline inspector Wang Qishanurged the anti-graft watchdog to strengthen internal conduct supervision at a symposium held on Wednesday.

Wang, chief of the Communist Party of China's (CPC) Central Commission for Discipline Inspection (CCDI), said the country still faces a severe and complicated situation in the fight against corruption.

More than 3,400 discipline inspectors nationwide have been punished since the 18th CPC National Congress in late 2012 when the incoming leadership launched a high-profile anti-corruption campaign.

Among the 3,400 punished anti-graft officials, 14 were from the CCDI, according to a statement released after the symposium.
