China's government on Sunday denounced the Trump administration's imposition of a long-threatened 10% tariff on Chinese imports while leaving the door open for talks with the U.S. that could avoid a deepening conflict.

The Trump administration is following through on its promise to impose 25% tariffs on goods imported from Mexico and Canada, and 10% on Chinese items Saturday, all linked to the fentanyl crisis. The Trump administration on Friday announced the tariffs would take effect Saturday.

China’s Ministry of Commerce said it would file a legal case at the World Trade Organization, but signaled it still wanted a stable relationship with the U.S.
