The Biden administration’s narrowly focused ban on Chinese-made solar products is designed to confront alleged human rights abuses in the Xinjiang region without stifling the fast-growing use of renewable energy in the U.S.

The order imposed Thursday, which affects the import of silica-based products made by Hoshine Silicon Industry Co., represents one of U.S. President Joe Biden’s biggest steps yet to counter alleged mistreatment of China’s ethnic Uyghur Muslim minority.

Yet it falls short of a broad regional ban some activists had urged on solar imports from Xinjiang, a manufacturing hub where advocacy groups and a panel of United Nations experts say Uyghurs and other minorities have been forced to work against their will. China has denied the allegations, saying they’re an attempt to undermine successful businesses.
