Washington: The FBI has said it is investigating Chinese economic espionage in nearly all of its 56 field offices in America, highlighting the depth of the threat to the US. FBI Director Christopher Wray told this to members of the Senate select Committee on Intelligence during a Congressional hearing on worldwide threat assessment.

"I think China writ large is the most significant counterintelligence threat we face. We have economic espionage investigations, for example--that's just one piece of it--in virtually every one of our 56 field offices," Wray said.
