U.S. President Joe Biden said on Wednesday he is concerned about Chinese hypersonic missiles, days after a media report that Beijing had tested a nuclear-capable hypersonic glide weapon, APA reports quoting Reuters.
Asked by reporters as he was boarding Air Force One for a trip to Pennsylvania whether he was concerned about Chinese hypersonic missiles, Biden said, "Yes."
Hypersonic weapons travel in the upper atmosphere at speeds of more than five times the speed of sound, or about 6,200 kph (3,853 mph).
The Financial Times said at the weekend that China had tested a weapon in August that flew through space and circled the globe before cruising down toward a target that it missed. China's foreign ministry denied the report.
