US Imposes Tariffs on the EU, Mexico, and Canada

US President Donald J. Trump’s administration announced on May 31 that it will no longer exempt Canada, Mexico, and the European Union from previously announced tariffs on steel and aluminum imports. This means tariffs—25 percent on imports of steel and 10 percent on imports of aluminum—will go into effect at midnight on June 1. The decision will strain US ties with some of its closest allies and has already sparked retaliation.
