A U.S. law broadly banning imports from China's Xinjiang region took effect Tuesday — a move aimed at adding pressure over Beijing's alleged use of forced labor among the Uyghur minority, and which could pose supply chain challenges.

The Uyghur Forced Labor Prevention Act, which was signed into law in December, is certain to further strain relations between the world's two largest economies as their rivalry intensifies in military, trade and technology fields.

The U.S. government had imposed import bans targeting certain products and companies over forced labor concerns in China, but the latest law has a wider coverage, applying to "any goods, wares, articles, and merchandise mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region."
