About 20 CIA informants were killed or imprisoned by the Chinese government between 2010 and 2012, as reported New York Times, damaging US information-gathering in the country for years.
It is not clear whether the CIA was hacked or whether a mole helped the Chinese to identify the agents, officials told the paper.
They said one of the informants was shot in the courtyard of a gov
ernment building as a warning to others.
The CIA did not comment on the report.
Four former CIA officials spoke to the paper, telling it that information from sources deep inside the Chinese government bureaucracy started to dry up in 2010. Informants began to disappear in early 2011.
The CIA and FBI teamed up to investigate the events in an operation one source said was codenamed Honey Badger.
he paper said this investigation had centred on one former CIA operative but there was not enough evidence to arrest him. He now lives in another Asian country.
In 2012, an official at China’s security ministry was arrested on suspicion of spying for the US. He was said to have been lured into the CIA. No other such arrests appear to have reached public attention during that time.
