Documented evidence of large-scale human rights abuses in China’s northwestern Xinjiang region has painted a clear picture that Beijing is perpetrating mass atrocities against Uyghurs and other Turkic Muslim ethnic groups. But even in the face of transparent evidence, the strategies the international community and the United States typically deploy to prevent atrocities have failed to stop the problem. The United States and like-minded countries have an obligation to act to end the ongoing atrocities and to protect the Uyghur people. While many important steps have been taken, none have had a noticeable impact on Beijing. It’s time for the international community to take stock of the atrocity prevention toolkit, to consider why it has failed the Uyghurs, and to discuss how these failures can inform updates or adaptations to respond to the Xinjiang crisis.
