The entities added include companies mining and processing critical minerals from Xinjiang, where Beijing has been accused of incarcerating more than one million Uyghurs and other Muslim minorities in a network of detention facilities.
Chinese officials strongly deny these claims.
The additions also include companies growing Xinjiang cotton and manufacturing textiles for global export, alongside those producing inputs for solar modules using polysilicon made in the region.
The companies affected include Zijin Mining Group and its subsidiaries in Xinjiang, alongside Huafu Fashion and 25 of its subsidiaries.
The Department of Homeland Security said entities added have been “linked to forced labour practices”.
The Uyghur Forced Labor Prevention Act was signed into law in 2021.
