I which part I said otherwise? Asia is a region, that includes countries like Japan, China, Taiwan, the Koreas, etc.... but I never said it was limited to China. My point was that the population of China is almost half of the world, if not pass that already, that is why I said that the christianity is not the biggest religion out there like the other user claimed.

Basically to make it easier, China, part of Asia, is almost half of the population, they are not in the mayority christians, so by that I am saying that christianity is not the biggest religion in the world, also, contemplating that there are christians, catholics and protestants, among other derivations of it, that makes your claim claim even more wrong.
