Four high-ranking officials are being prosecuted on corruption charges, the country's top prosecuting body announced on Wednesday amid the nation's continued campaign against corruption.

Su Rong, a former State official who once served as Party chief in the provinces of Jiangxi, Qinghai and Gansu, was charged at People's Intermediate Court in Jinan, Shandong province, according to a statement from the Supreme People's Procuratorate.

He had been one of the vice-chairmen of the Chinese People's Political Consultative Conference until disciplinary authorities began an investigation into him in June 2014.
