BEIJING -- Disciplinary authorities have investigated 440 officials at or above provincial or corps level for corruption over the past five years as the Communist Party of China pledges sweeping victory over the threat to the Party, an official said Thursday.

Among them, 43 members and alternate members of the CPC Central Committee, as well as nine members of the Central Commission for Discipline Inspection, were investigated, said Yang Xiaodu, deputy secretary of the CCDI, at a press conference on the sidelines of the 19th CPC National Congress.
