Terrorism in China?

Going through my RSS feeds, I just saw the article "Turkestan Islamic Party takes credit for Shanghai and Kunming bus blasts, and warns of more to come; China denies claims" published on Shanghaiist.

(...) this latest video issued by a certain Turkestan Islamic Party (...) sent a tingle down our spine. In it, a Commander Seyfullah claims credit for the following, according to an AFP report: the May 5 Shanghai bus explosion which killed three; another Shanghai attack (not sure which one exactly); an attack on police in Wenzhou on July 17 using an explosive-laden tractora bombing of a Guangzhou plastic factory on July 17 and the July 21 bombings of three buses in Kunming and Minshan in Yunnan Province

Scares the shit out of me.

Is China the new America?
