China’s Uighur minority are being moved from their homes and mass detention camps into factories to work under conditions that strongly suggest forced labour for suppliers to a range of multinationals including Apple and Huawei, according to new research. More than 80,000 Uighur residents and former detainees from the north­ western region of Xinjiang have been transferred to factories in a range of supply chains including electronics, textiles, and automotive, according to the report released on Sunday by the Australian Strategic Policy Institute (ASPI). At least 83 Chinese and foreign multinationals are known to be benefiting from “forced Uyghur labour under a state-sponsored labour transfer scheme”, the think-tank found.

It names 27 factories in nine Chinese provinces as beneficiaries of workers transferred from Xinjiang since a crackdown on the Uighur Muslim minority began in early 2017. While a handful of companies had previously been named in public reports, their supply chains were concentrated in Xinjiang itself, particularly the cotton industry. Over the past three years, the Chinese government has detained some 1.8m Uighur Muslims in a system of camps in the region. While Beijing says some have been released, many have been sent to work in factories across China as part of government-organised labour-transfer schemes. The schemes also include individuals who have not previously been interned.

The transferred workers typically undergo “ideological training outside working hours, are subject to constant surveillance, and are forbidden from participating in religious observances”, according to ASPI. The think-tank arrived at their conclusions by cross-referencing state media and Chinese government reports announcing Xinjiang work-transfer projects to lists of suppliers for international brands, as well as local companies’ claims of who they were supplying.

Family members of forced labourers in Xinjiang have previously said their relatives are not allowed to leave the factories and that communications with the outside world, if allowed at all, are monitored. Thefactories implicated by Xinjiang labour transfers stretch as far as Nanchang, a city in southern China where Apple supplier 0-Film Technology has three factories, according to Apple’s supplier list. 0-Film also says it supplies Huawei and other multinationals with camera and touchscreen components. Local media in southern Xinjiang reported that in the space of a few days in 2017, 700 workers were transferred to 0-Film’s Jiangxi plants. Although local media did not mention they were ex-detainees, it described the work-transfer programme as aiming to “gradually change their ideas
