I agree that FEM don't count because they might as well be white americans, because they have american citizenship. And in terms of Charice, she's promotes like she's the girl version of Justin Bieber so it's not like she's bringing anything new, at least with the Wonder Girls they tried to bring something new. I would still put it that no asian singer has made it because they can't really 'make' it if they just plan on making music to fit the market - I think making it means having their music accepted for what it is, sells alot AND becoming a well-known name. In this way Lea Salonga is probably one of the few I know, although you could argue that Muscial stars don't count.
