I don’t in general trust the FBI after its treatment of Trump, but they have probably got it right on the threat of China:

“China is threatening the U.S. economy—and national security—with its relentless efforts to steal sensitive technology and proprietary information from U.S. companies, academic institutions, and other organizations, FBI Director Christopher Wray said today. Wray described the threat from China as “diverse” and “multi-layered.” He noted that the Chinese government exploits the openness of the American economy and society. “They’ve pioneered an expansive approach to stealing innovation through a wide range of actors,” Wray said during opening remarks at the half-day Department of Justice China Initiative Conference in Washington, D.C. Wray told the audience that China is targeting everything from agricultural techniques to medical devices in its efforts to get ahead economically. While this is sometimes done legally, such as through company acquisitions, China often takes illegal approaches, including cyber intrusions and corporate espionage. “They’ve shown that they’re willing to steal their way up the economic ladder at our expense,” he said. The FBI is using traditional law enforcement techniques as well as its intelligence capabilities to combat these threats. He said the FBI currently has about 1,000 investigations into Chinese technology theft. “They’ve shown that they’re willing to steal their way up the economic ladder at our expense.”
