OP/TFA implied that it was indeed Chinese, by encroaching on territorial waters and crowding out native fleets. At least that was my reading of the article and the above comment.
Yes, and I was arguing against that idea. The other countries didn't suddenly stop fishing in the area. And FWIW all of them are about equally "native" to the region, as in, people from all the surrounding coasts have been fishing there for centuries. Just the scale is new.
