Foreign Affairs journal has an article by Robert Kaplan called China's Grand Map. For the Free Tibet folks, I repeat, it is too late, China owns Tibet. They don't want India to have influence and Tibet has minerals. The Chinese don't really want to rule non-Chinese, but want the minerals.
I am trying to imagine the Chinese official in say, Sudan. Honorable President Bashir, we do not care who rules, as long as you are stable. We just want your minerals.
