Yes, I think that's probably a fair assessment in this case. In fact, I listened to Lobsang Sangay's testimony before the committee as well, and I know that's a point he's drawn. The co-option of the elite can be a factor.
In the People's Republic of China politically overall, I think that there are very, very few Tibetans who make it to high-level positions within that system, but certainly within the Tibet Autonomous Region you see a mix of ethnic Han and ethnic Tibetan leaders within the political system.
