No, or rather, not necessarily. Asians in the US are a very different group from Asians in Asia. Recent immigrants are heavily overrepresented, and I believe that the difficulty of immigrating to the US from most Asian countries selects for fairly capable people.

That being said, Asia does account for a ridiculous proportion of the world's population, so it probably wouldn't be a bad bet to bet on an Asian country becoming the next dominant superpower. You know, on purely general principles.
