DJI, the world's largest drone manufacturer that sells more than half of all U.S. commercial drones, asked a U.S. District Judge in Washington to order its removal from the Pentagon list designating it as a "Chinese military company," saying it "is neither owned nor controlled by the Chinese military."

DJI claims it operates solely in the commercial sector with no military ties, disputing the Pentagon's designation.

The China-based maker of more than half of all commercial drones in the U.S. went to court to fight its placement on a list of companies said to be working with the Chinese military.
