Swedish clothing giant H&M said on Tuesday it was ending its relationship with a Chinese yarn producer over accusations of “forced labour” involving ethnic and religious minorities from China’s Xinjiang province.

The fashion retailer specified that it did not work with any garment factories in the region and that it would no longer source cotton from Xinjiang, which is China’s largest cotton growing area.

A report by think tank the Australian Strategic Policy Institute (ASPI), published in March, pointed to H&M as one of the beneficiaries of a forced labour transfer programme through their relationship with the dyed yarn producer Huafu’s factory in Anhui.

However, H&M said in a statement that it had never had a relationship with the factory in Anhui, nor Huafu’s operations in Xinjiang.
