US government agencies from the Pentagon to Nasa will be banned from buying Huawei equipment after the Trump administration implemented a congressional measure to crack down on Chinese companies seen as security threats.
A rule issued by the administration bans Huawei, the Shenzhen-based telecoms company, and other Chinese groups from supplying the federal government. It also covers ZTE, a telecoms company; Hikvision and Dahua, manufacturers of surveillance cameras; and Hytera, which produces two-way radios.
The move is the latest example of the mounting concern in Washington about the potential for Chinese technology companies to help Beijing conduct cyber espionage. Much of the concern has been aimed at Huawei because of its role building ultra-high-speed 5G networks around the world.
