The former deputy head of China's top economic planning agency received 10 million yuan ($1.6 million) in bribes, media outlets said Wednesday, citing sources with the ruling Communist Party's disciplinary commission.

Liu Tienan was ousted in May from his post with the National Development and Reform Commission.

Authorities began investigating Liu after prominent journalist Luo Changping published a story last December accusing the NDRC official of ties to a shady businessman and of lying about his academic credentials.

Liu was expelled from the Communist Party earlier this month and will now face criminal charges.

Investigators found that Liu, 59, had 25 bank accounts holding the equivalent of $17 million, as well as 25 diamonds cumulatively valued at 870 million yuan ($142 million), the Communist Party sources said.

Since taking office in March, Chinese President Xi Jinping has pursued a campaign to root out corruption at all levels of the government and ruling party. EFE
