Back in the days Asian people found out pretty fast that the only way to dominate the planet is not by intuition and pure intelligence (that is reserved for white people)
the only way to mark this planet is to breed like crazy and to make up in numbers rather than quality.
Well, China has had their internal conflicts, but they are very insular, as in not branching out to other continents, intent on staying where they are...it wasn't until recently, that they decided to act like the Euros and go the African route.
Africans, regardless of disease have a high infant mortality rate...
