Thermo Fisher Scientific Inc. says it will no longer sell or service genetic sequencers in China's mostly Muslim region of Xinjiang following criticism that they were used for surveillance that enabled human rights abuses... The company in Waltham, Massachusetts, cited its "values, ethics code and policies"... Thermo Fisher faced criticism from human rights groups and American lawmakers for supplying the equipment used to identify individuals in Xinjiang. The region is under intense security measures as part of what the government says is an effort to stop extremism and separatist movements... As many as 1 million Uighurs, Kazakhs and other Muslim minorities are detained in political education camps in Xinjiang, according to U.S. officials and UN experts. The government says those camps are vocational training centers designed to rid the region of extremism.
