The U.S. government on Tuesday strengthened its warnings to businesses about the growing risks of having supply chain and investment links to China's Xinjiang region, citing forced labor and human rights abuses there.

"Given the severity and extent of these abuses, businesses and individuals that do not exit supply chains, ventures, and/or investments connected to Xinjiang could run a high risk of violating U.S. law," the State Department said in a statement.

Signaling broader U.S. government coordination on the issue, the Department of Labor and the U.S. Trade Representative's Office joined together in issuing the updated advisory, first released on July 1, 2020, under the Trump administration by the State, Commerce, Homeland Security and Treasury departments.
