In Japan will stand up to China, says PM Shinzo Abe, there's mention of Japanese plans to shoot down Chinese drones:
The statement was referring to reports that Mr Abe had approved defence plans that envisaged using air force planes to shoot down unmanned Chinese aircraft in Japanese airspace.
Under international law (as opposed to Japanese domestic law), is Japan allowed to shoot down drones that are within its own airspace? Or would it need to declare war first?
