China is developing its own drone technology -- for its own military and for sale around the world.
It’s safe to say, then, that Chinese drones conjure up a particularly intense sense of alarm that the media has begun to embrace as a license to panic. China is indeed developing a range of unmanned aerial vehicles/systems (UAVs/UASs) at a time when relations with Japan are tense, and when those with the U.S. are delicate. But that hardly justifies claims that “drones have taken center stage in an escalating arms race between China and Japan,” or that the “China drone threat highlights [a] new global arms race,” as some observers would have it. This hyperbole was perhaps fed by a 2012 U.S. Department of Defense report which described China’s development of UAVs as "alarming."
That’s quite unreasonable. All of the world’s advanced militaries are adopting drones, not just the PLA. That isn’t an arms race, or a reason to fear China, it’s just the direction in which defense technology is naturally progressing. Secondly, while China may be demonstrating impressive advances, Israel and the U.S. retain a substantial lead in the UAV field, with China—alongside Europe, India and Russia— still in the second tier. And thirdly, China is modernizing in all areas of military technology – unmanned systems being no exception.
