In China, the further a province is from Beijing, the less likely it is to follow the CCP in all ways. There is quite a bit of autonomy for the provinces, so long as they don't push back on major initiatives. The western provinces (Tibet (called XiZang" in China), Xinjiang, and QingHai make up their "west coast"... and 2 out of 3 certainly seem to be getting punished for failing to toe the line. In the internet age, these failures to obey are magnified, and thus the dragon's attention is compelled to make sure that they don't "lose face". Almost predictable, really.
(Odd choices, I know... but it can't be Iran... they're about to democratize on their own. Not Iraq or Afghanistan... we're still there. Not Saudi Arabia... too much control over oil. Jordan? Their king seems almost rational. Pakistan? Nukes. Egypt? The Suez Canal. Those were the only 3 other state sponsors of terror I could think of!)

There are a few versions of it out there, one is 3 DVDs and another seems to be more than a dozen.
