UN ambassadors from 37 countries released a letter Friday defending China's treatment of Uighur and other minorities in the Xinjiang region, in direct response to Western criticism earlier this week. Envoys from across the EU -- along with Australia, Canada and Japan and New Zealand -- had earlier co-signed a text denouncing China's conduct in Xinjiang, where one million people, mostly ethnic Uighurs, are reportedly being held in internment camps. "We commend China's remarkable achievements in the field of human rights," said the letter, also signed by Myanmar, the Philippines, Zimbabwe and others.
