Tibet presents an explosive domestic political issue for China which the latter would benefit from eliminating  Tibet, and the resistance Tibetans continue to show to Chinese rule presents a toxic domestic and international political problem that costs far more than it worth.  Domestically, violence in Tibet is the most serious domestic disturbance facing the Chinese government, and the fact that there is nearly constant violence between Han Settlers and Tibetans forces the Chinese to alienate everyone in order to contain it. Furthermore, the economic and political disenfranchisement of the Tibetan people is an enormous domestic problem, as it has led to large numbers becoming unemployed and moving to other parts of China where they form an underclass.  Internationally, the Tibetan issue keeps China’s Human Rights record in the news and almost torpedoed the 2008 Olympic games. Given that China is already losing money on the province, it may well be worth it for China to jettison it in order to gain much greater international benefits.
