Quote : China's apparent progress is likely to spur others, especially India and Japan, to accelerate their own UAV development or acquisition programs.

The Chinese have managed to create artifical eatable eggs that taste better then the real ones..poor chickens in the same way.. they are far superior in hidden technology then any country on earth..Drones for them would be child's play.
Don't you think they already have built far superior ones?
The report says that "China is investing considerable time and money to develop drone technology, and is actively promoting its products on the international market"
not everything is shown to the world..this is how the Chinese operate..

The drones on display are probably a couple of generations older than the ones they are operating..
