China accused the United States on Thursday of faking facts, after the head of the FBI said that Chinese hacking likely cost the U.S. economy billions of dollars every year.
Charges over hacking and internet spying have increased tension between the two countries. In May, the United States charged five Chinese military officers with hacking into U.S. companies, prompting China to suspend a Sino-U.S. working group on cyber issues. China has denied wrongdoing.
Speaking on CBS’ 60 Minutes program on Sunday, FBI Director James Comey said Chinese hackers were targeting big U.S. companies, and that some of them probably did not even know they had been hacked.
Chinese Foreign Ministry spokesman Hong Lei, asked about Comey’s remarks at a daily news briefing, said China banned hacking and “firmly strikes” against such criminal activity.
