From the Associated Press:
China’s government has grown increasingly sensitive about Tibet in the two years since rioting in the regional capital of Lhasa left 22 people dead and led to the most sustained Tibetan uprising against Chinese rule in decades. Violent clashes and demonstrations swept Tibetan towns throughout western China, where occasional protests still continue, and security remains extremely tight.
Now, activist groups say a growing number of Tibetan intellectuals are coming under pressure from authorities determined to squelch all forms of dissent.
The government has always sought to silence critics of China’s policies in Tibet, where a debate rages over how much autonomy, from religious freedom to outright independence, the Himalayan region deserves. But now officials appear to be expanding their reach and targeting even those previously considered allies or at least innocuous.
