Only if we stretch to say that Kim, who was born in California, is actually Asian. In my book, he's American, of Asian descent. Not meaning to split hairs, but that's a fair difference.
As far as golf goes, KJ still has some juice left in the tank, though he didn't show it this week at the Players. He has the ball striking game for majors, especially a US Open type game. And one would have thought he's fare better here this week - obviously he's fighting his swing right now. But Kim seems to be a special talent, and could very easily sneak up and do big things. Majors are a different animal, and unless that other top player of partial Asian descent relents a bit, it will be tough for Kim. Also, majors historically take time and experience. Not always, but usually you have to contest in them once or twice before you win it. He'll be fun to watch though!
