President Donald Trump has slapped tariffs on Chinese goods, accusing Beijing of allowing fentanyl and precursor chemicals to be shipped to the United States.

The White House says fentanyl smuggled to the U.S. justifies tariffs against Canada, China and Mexico. But fentanyl deaths and smuggling have been dropping fast — and Canada plays almost no role.

President Trump has threatened to impose tariffs on Canada over drug trafficking, equating it with Mexico. U.S. government reports do not support the claim.
