No doubt there are physical differences in body type between ethnicities.
People in equatorial regions tend to have long, thin limbs, whereas people
in subtropical regions tend to have shorter limbs and a stockier, heavier
appearance.

However, I suspect alot of the difference is that many people in Asia are
just more physically active (though China's rate of obesity in urban areas
is increasing, it is nowhere near the level in the US), and in many parts
the society is still agrarian.
