U.N. experts and rights groups estimate over a million people, mainly Uyghurs and other Muslim minorities, have been detained in a vast system of camps in Xinjiang in recent years.

Parts of the reports could be released publicly as soon as next week. Reporting by Nichola Groom; editing by Richard Valdmanis and David GregorioOur Standards: The Thomson Reuters Trust Principles.
