The head of the FBI said Tuesday that China is pushing its preferences in the US election as part of broad intelligence operations, whose economic impact he called unprecedented.

Christopher Wray, director of the Federal Bureau of Investigation, did not say whether China backed either President Donald Trump or his presumptive Democratic rival Joe Biden, both of whom have harshly criticized Beijing.

“China’s malign foreign influence campaign targets our policies, our positions, 24/7, 365 days a year,” Wray said at the Hudson Institute.
