According to reports from CCTV News, Canadian Minister of Industry Mélanie Joly has made it clear that Canada will retaliate against U.S. President Trump's plan to impose a 50% tariff on copper imports. Joly's stance is firm, stating, "We will firmly oppose and never compromise," although she did not disclose specific details of the retaliation. Previously, on the evening of the 9th, Trump posted on social media that he would impose a 50% tariff on copper imported into the United States, which will officially take effect on August 1. According to data from Canada's Department of Natural Resources, in 2023, Canada's copper and copper-based product exports reached 9.3 billion Canadian dollars, with about half going to the United States.
