Anyone who has the slightest pretext of considering themselves informed on the question of current Chinese Communist Party policy in Tibet needs to enter into an extended reconnaissance of this book: Melvyn Goldstein’s History of Modern Tibet, Vol. 2: The Calm Before the Storm, 1951-1955 (University of California Press, 2007).
Essentially, this text makes clear that the 1950s are the crucial decade for understanding contemporary Sino-Tibetan relations/tensions/the ability and inability to cooperate.
Goldstein is widely read in Tibet’s 1950s history, but mainly he cities his own mammoth research databases, relying but sparingly on work by Grunfeld 1996, Knaus 1999, Shakya 1997, and Smith 1996. 
Goldstein expends virtually no energy describing the CCP efforts to justify the Tibet policy to the outside world. In the 1950s, this international propaganda work would be done, in part, by fellow travelers like the French feminist Simone de Beauvoir and American friends Israel Epstein and Anna Louise Strong.

Sharpe, 1996); John Kenneth Knaus, Orphans of the Cold War: America and the Tibetan Struggle for Survival (New York: Public Affairs, 1999); Tsering Shakya, The Dragon in the Land of Snows (New York: Columbia University Press, 1999); Warren Smith, China’s Tibet: Chinese Press ARticles and Policy Statemens on Tibet, 1950-1989 (Cambridge: Cultural Survival, 1989); Warren Smith, Tibetan Nation: A History of Tibetan Nationalism and Sino-Tibetan Relations (Boulder, Colorado: Westview Press, 1996.
 Strong’s quirky, classic on-the-spot justification for the CCP 1959 revolt suppression, When Serfs Stood Up in Tibet, is available in full online. Glory be!
