The White House on Friday added 43 Chinese companies to a blacklist that is meant to block imports made with alleged forced labour in Xinjiang, marking the third time this week Washington has announced measures aimed at China.

Enforcing the Uygur Forced Labour Prevention Act (UFLPA), the Department of Homeland Security increased its entity list by 30 per cent to include companies in sectors ranging from food and cotton to pharmaceuticals, metals and lithium production.

The UFLPA was passed by Congress in 2021 to target imports from the Xinjiang Uygur autonomous region in western China and to prevent goods produced under alleged forced labour conditions from entering the US market.

“The newly listed entities are connected to the production and sale of goods made in Xinjiang or with the forced labour of Uygurs and other groups specified in the UFLPA,” said State Department spokesman Tommy Pigott, citing seafood, gold, copper, transportation infrastructure, aluminium, tomatoes, cotton, garments and frozen food, among the targeted sectors.

The expanded list included one ‌of China’s largest capacitor manufacturers, Hunan Aihua Group, with a US Federal Register notice saying the government believes the company sources chemical foil and other materials from the region.
