The violence that has claimed at least 156 lives in the western Chinese region of Xinjiang this week is rooted in long-standing grievances among China’s Uighur minority. The Turkic-speaking Muslim Uighurs were traditionally the dominant ethnic group in the region whose Mandarin name, Xinjiang, means simply “New Frontier” perhaps a reflection of the fact that the region was only brought under Beijing’s control in its entirety during the 19th century rein of the Qing dynasty.
