Prosecutors with the International Criminal Court have rejected calls from Uyghur exiles to investigate China for genocide. Exiled Uyghurs have accused Beijing of holding more than 1 million people from mostly Muslim minorities in reeducation camps. The International Criminal Court said it was unable to act because the alleged crimes occurred in China, which is not a signatory to the ICC.

This comes as China is facing new accusations of relying heavily on forced labor to pick cotton in the province of Xinjiang, which produces more than a fifth of the world’s cotton.
