Details of recent unrest in Xinjiang will never fully come to light. Like the Tibetan riots last year, the Gulja massacre 12 years earlier or the violence at Tiananmen two decades ago, there will be no public probe to establish the truth of events, and wounds festering in private will not heal.
But long after this summer’s riots, the lingering impression will be that Beijing’s talk of ethnic harmony and national unity is hollow, while discontent with its authoritarian rule is strong.
