China’s top procuratorate has charged the former head of the country’s geological survey agency with bribery and leaking state secrets.

Zhong Ziran, 62, is accused of using his senior positions at the Ministry of Natural Resources and its affiliated China Geological Survey to receive a “particularly large” amount of bribes, the Supreme People’s Procuratorate said in a notice on its website on Friday.

The sum involved has not been disclosed.

The statement added that Zhong, who was also the Communist Party chief of the China Geological Survey, had deliberately leaked state secrets.

The nature of the breach was “serious” and Zhong had breached the State Secrets Act, it said, but did not provide details.
