In October 2021, The New York Times citing a leaked CIA cable, reported that the CIA had admitted to have lost a "troubling number of informants" recruited from countries including China in recent years, with informants being killed, captured or compromised. The leaked cable comes amid China's recent efforts in hunting down CIA sources to turn them into double agents.[16] The memo also mentions a "breach of the classified communications system" that led to spy networks in China being caught and that some officials believe that treasonous US intelligence officers may be the culprits responsible for the arrests and execution of CIA spies.[16]
