China is permitting more than 2,000 ethnic Kazakhs to surrender their Chinese citizenship and leave the country, the Kazakh Foreign Ministry said this week. The move may be a sign that China is feeling international pressure about its widespread detention of Muslims in the far western Xinjiang area. The detention of ethnic Uyghur, Kazakh and other minorities in internment camps has caused tension between China and neighboring Kazakhstan. China is a major trading partner, and Kazakhstan’s state-restricted media had mostly avoided reporting on the issue. But activists say pressure for action has slowly increased, following an Associated Press story on the camps in May and other international media reports. The Kazakh Foreign Ministry has confirmed that China has agreed to let over 2,000 ethnic Kazakhs leave. It did not say who could leave or why they were able to leave.
