Seven Apple suppliers have been linked to forced labor programs that are suspected to be related to the alleged Chinese genocide of Uyghur Muslims in the country’s Xinjiang region. That’s according to a new human rights report shared with The Information, picked up on by AppleInsider.

The Apple supply chain partner produce components, coatings, and offer assembly services to the Cupertino tech giant. At least five received thousands of Uyghur and other oppressed minority workers at specific plants that did work for Apple, according to an investigation by human rights groups and The Information. According to the report, evidence suggests that Advanced-Connectek, Luxshare Precision Industry, Shenzhen Deren Electronic Co., Avary Holding, AcBel Polytech, CN Innovations, and Suzhou Dongshan Precision Manufacturing Co. participated in the forced labor programs. To identify those manufacturers and supply partners, the investigation used previously unreported public statements, images, and videos by Chinese government offices and state-run media organizations. That evidence found that the companies participated in what the Chinese call a poverty alleviation program.
