The Philippine military chief demanded Wednesday that China return rifles and other equipment seized by the Chinese coast guard in a disputed shoal and pay for damage in an assault he likened to an act of piracy in the South China Sea.
That "China/Taiwan" is just kinda thrown in there without even an asterisk or anything
(Actually I guess leaving Taiwan out of the legend entirely would have looked like an accident or something, and having a separate color for it would have been a huge deal and they'd have started to get phone calls, and so they just shrugged and put that down and said you know what it's not a perfect world let's move on)
Bloody hell, you are right (well, sort of; apparently it's complex.) That's convenient for the map makers, I guess, although best of luck to them in enforcing any of it (and according to that article they've sort of clarified that that doesn't mean they're actually claiming the sea, as best as I can understand it.)
