Lawmakers in Washington are seeking to ban new sales of drones from two dominant Chinese manufacturers, arguing they could be used to spy on Americans and that the low-cost models are hurting the U.S. drone industry.

The economic and technological rivalry between the U.S. and China has come to the drone market, where Chinese-made flying devices are a dominant player in America.

A broader ban is worrisome for Americans for whom drones have become a part of their lives and work. It could disrupt wide-ranging operations, from law enforcement to mapping and filmmaking that drone operators say are viable because of the low cost and high performance of the Chinese drones. American-made drones just aren’t comparable, they say.
