URUMQI, China—The video posted online last month looks much like ones from Middle East jihadist groups. It shows what appears to be a man making a suitcase bomb and grainy footage of an explosion at a crowded train station here. The soundtrack plays an Arabic chant inciting holy war.
But the video isn’t meant to rally followers in Iraq or Syria. Its appeal is to China’s 10 million Uighurs, a largely Muslim ethnic group from this northwestern region of Xinjiang, some of whom have resisted Chinese rule for decades.
The Internet has been a key propaganda tool for Mideast militants. Now, it appears to be helping spread the ideology and tactics of violent jihadism to this remote corner of the Muslim world, poorer parts of which came online only recently.
The video was posted after a knife-and-bomb attack at a train station in Urumqi, Xinjiang’s capital—one of a series of assaults in Chinese cities since October that have made unrest emanating from the region the biggest domestic-security issue for China’s leadership.
In the video, a speaker of Uighur (pronounced WEE-gur) congratulates the train-station bombers, declaring: “In this blessed jihadist act, many Chinese migrant aggressors were killed and wounded. As for those remaining, it put terror into their hearts.”
Chinese officials are pointing to an upsurge in Uighur language videos like this and other religious-extremist material online as a key factor behind the recent attacks. China’s censors block most such material, but Chinese officials and some Uighurs say some locals find ways to access it.
China’s government launched a crackdown on terrorist material online on Friday and took the unusual step Tuesday of broadcasting a documentary on state television including jihadist video clips it said were from Xinjiang militants.
The film, jointly produced with Chinese police, said such material had inspired and helped to train the alleged perpetrators of several recent attacks, including an apparent suicide bombing—a tactic rarely used by Uighurs in the past—that killed 43 at an Urumqi market last month.
The narrator of the film said most relevant videos were produced outside China, posted online via countries including Turkey, which has strong cultural links to Xinjiang, and then spread within the region via memory cards, social media and other electronic means.
