BEIJING, Sept 1 (Reuters) - China firmly opposes the release by the United Nations Human Rights Office of its "so-called Xinjiang-related assessment", said China's Permanent Mission to the United Nations Office in Geneva on Thursday.

The report is based on the assumption of guilt, uses false information, and is a farce planned by the United States, Western nations and anti-China forces, said Liu Yuyin, spokesperson of the Permanent Mission in Geneva, in a statement http://geneva.china-mission.gov.cn/ryrbt/202209/t20220901_10758767.htm on its website.
