Lurker, go to Siberia as I have and talk to what is left of the native peoples. They will tell you, as they told me, how Siberia was conquered by force of arms. It started under the Czars and continued right up through the Soviets with native peoples being displaced, killed, or forced to work under the control of the state.
As for China, look at Tibet. It's only the most recent of a long list of armed conquests by the Han - the principal ethnic group in China. I used to have a web site bookmarked about the current situation in Inner Mongolia. I'll have to look it up again and I'll PM it to you if you like. Western China is not populated by Chinese at all but by Uighirs, a Turkic people. Now they are being displaced as the central government sends thousands of Han there as "colonists". There is an armed rebellion ongoing there. It's pretty low-key so far, but it exists. In 1945 this was the area in which the short-lived country of Turkestan was born. It died soon after under the weight of Maos Peoples Army.
