In February 2019, Thermo Fisher Scientific announced that it would stop selling its equipment in Xinjiang. In June 2020, Thermo Fisher Scientific was reported to sell its equipment to security services in China for use in what was alleged as part of a genetic surveillance program.
A report from the Australian Strategic Policy Institute found that Thermo Fisher Scientific collaborated with the Chinese Ministry of Public Security to develop a Huaxia PCR amplification kit specifically to identify the genotypes of Uyghur, Tibetan and Hui ethnic minorities. In June 2021, The New York Times reported that, despite bans, Thermo Fisher Scientific equipment continued to be sold to police in Xinjiang.
