Canadian Industry Minister Mélanie Joly has made it clear that Canada will retaliate against U.S. President Trump's move to impose a 50% tariff on copper imports. Joly took a tough stance, saying, "We will firmly oppose and will not compromise," but she did not reveal specific details of the retaliation. Previously, Trump posted on social media on the evening of the 9th that he would impose a 50% tariff on copper imported into the United States, and that the tariff would officially take effect on August 1. According to data from Natural Resources Canada, Canada's exports of copper and copper-based products reached CAD 9.3 billion in 2023, about half of which were sold to the United States.
