The Supreme People's Procuratorate said on Tuesday it has investigated 32 corrupt officials at the ministerial level and above over the past five years.
Cao Jianming, chief prosecutor, said 13,368 officials at the county level and above were probed for graft between January 2008 and late August this year.
About 167,000 people were charged with embezzlement and bribery, and 148,931 were convicted, he said.
He made the remarks while delivering a report on the top procuratorate's work against embezzlement and bribery at the ongoing bimonthly session of the Standing Committee of the National People's Congress, which runs from Monday to Friday.
Among those investigated in graft cases, 65,629 civil servants have been investigated for taking bribes, while 23,246 people were investigated for offering bribes, Cao said.
The number of bribe takers between 2008 and 2013 has increased by 19.5 per cent compared with the previous five years, while the number of people who offered bribes has increased by 60.4 per cent, he said.
Cao said that the procuratorate has prevented an estimated 37.7 billion yuan (S$7.65 billion) of economic losses through investigating the cases.
The anti-graft agencies have paid special attention to several key sectors, including land use, property transactions, pharmaceutical sales, government purchases and public infrastructure projects, Cao said.
