FBI Director: China No. 1 Counter-Intelligence Threat to the US Masood Farivar The FBI has more than 1,000 investigations of U.S. intellectual property theft in all 50 states with nearly all leading back to China, FBI Director Christopher Wray said, calling China the No. 1 counter-intelligence threat to the United States. Testifying before the Senate Judiciary Committee, Wray described the threat as "more deep, more diverse, more vexing, more challenging, more comprehensive and more concerning than any counter-intelligence threat that I can think of." The Chinese threat ranges from cyber intrusions to corruption of insiders at U.S. companies small and large, Wray said, citing a series of recent Chinese economic espionage cases investigated by the FBI. U.S. academia, he added, remains particularly vulnerable to Chinese spying efforts to steal publicly-funded proprietary research . "It's an all tools approach by them," Wray said. "Therefore, it requires an all tools approach by us."
