A number of companies and brands have been linked to labor forced on Uighur Muslims by the Chinese government, according to multiple reports.

The Washington Post reported Tuesday that Apple supplier Lens Technology uses Uighur workers in its factories, according to documents obtained by the Tech Transparency Project. These workers were transferred from labor camps in the Xinjiang region of western China, WaPo reported.

Apple, which has said that it is committed to donating to organizations that “challenge racial injustice and mass incarceration,” is not the only company to come under scrutiny for its links to slave labor. In a spring 2020 report titled “Uyghurs For Sale,” the Australian Strategic Policy Institute found that at least 83 popular, household-name brands are “potentially directly or indirectly benefiting from the use of Uyghur workers outside Xinjiang through abusive labour transfer programs as recently as 2019.”
