China's court system concluded 45,000 graft cases in 2016, implicating 63,000 people, a work report of the Supreme People's Court (SPC) said Sunday.

The defendants included 35 former officials at the provincial and ministerial level or above, and 240 at the prefectural level, said the report to be delivered by Chief Justice Zhou Qiang at a plenary meeting of the annual session of the National People's Congress (NPC).

Courts at all levels convicted 2,862 criminals of bribery, and concluded 15,000 cases involving corruption, embezzling funds and other crimes found in poverty alleviation.

Since the 18th National Congress of the Communist Party of China in 2012, China has launched a sweeping fight against corruption, which the top leadership announced late last year "has gained crushing momentum."

In 2016, procurators investigated 47,650 people for their suspected involvement in duty-related crimes, according to a work report of the Supreme People's Procuratorate, which will be delivered by Procurator-General Cao Jianming at the plenary meeting.

Prosecution proceedings were launched against 48 former officials at the provincial and ministerial level or above, including Ling Jihua and Su Rong, both former vice chairmen of the country's top political advisory body, and Bai Enpei, a former senior lawmaker with the NPC, the report said.

In particular, procurators investigated 17,410 lower level officials suspected of corruption in land expropriation and demolition, social security, management of agriculture-related funds and other issues concerning people's well-being, according to the report.
