Since assuming office four weeks ago, President Trump has already slapped a 10% tariff on all Chinese imports for not stopping fentanyl trafficking.

He also announced, then delayed by a month, 25% tariffs on goods from Mexico and non-energy imports from Canada.

March 12 has been set as the start date for 25% tariffs on all imported steel and aluminum, ending exemptions for Canada, Mexico, European Union and other trading partners.
