The United States Government is to clip the wings of its civilian drone programme amidst continuing fears China could co-opt the tech to conduct espionage. Part of the 810-strong drone fleet -- used for such diverse tasks as monitoring endangered species and mapping landscapes -- was made by Chinese firm DJI. The move -- which will likely see the drones only fly in emergencies, such as to aid firefighting efforts -- builds on the temporary ban that began in October 2019. DJI Sciences and Technologies Ltd is a Chinese tech firm based out of Shenzhen, Guangdong province. The acronym DJI is short for'Dà-Jiāng Innovations'.
