President-elect Donald Trump said his incoming administration would slap new tariffs on imported goods from Mexico, Canada and China, solidifying a key campaign promise that could have a major impact on trade.

Trump said in a post on Truth Social that he plans to impose a 25% tariff on products imported from Mexico and Canada, framing the proposal as a response to the ongoing fentanyl crisis. Trump said that he would also seek to impose additional tariffs on China.
