WASHINGTON (Reuters) -The United States has banned imports from another tranche of companies over alleged human rights abuses involving the Uyghurs in China, targeting more than 30 textile, mining and solar entities, a federal government notice published on Tuesday said.

The companies were added to the Uyghur Forced Labor Prevention Act Entity List, which restricts the import of goods tied to what the U.S. describes as China's human rights abuses and ongoing genocide in the Xinjiang Uyghur Autonomous Region.

U.S. authorities say Chinese authorities have established internment camps for Uyghurs and other religious and ethnic minority groups in China's western Xinjiang region. Beijing has denied any abuses.
