The US Department of Homeland Security has reportedly warned US firms against using Chinese-made drones, saying they give Beijing “unfettered access” to company data. The move comes amid a wider crackdown on Chinese tech.

In a notice circulated to the US tech industry and seen by Reuters, the DHS warned that US officials have “strong concerns about any technology product that takes American data into the territory of an authoritarian state that permits its intelligence services to have unfettered access to that data or otherwise abuses that access.”

No specific manufacturers are named in the report, but almost 80 percent of all drones used in the US and Canada are made by DJI, a firm located in Shenzen, China. DJI products have a diverse range of users, from filmmakers to police departments. The US Army, however, banned the use of DJI drones in 2017, citing similar security concerns to the DHS’ latest report. (RT)
