U.S. President Donald Trump has pledged to place 25% tariffs on imports from Mexico and Canada from Feb. 1 if the two countries are not judged to be doing enough to stop the flow of fentanyl into the United States.

President Donald Trump's pick to lead the Commerce Department has told US lawmakers that Canada and Mexico can avoid blanket tariffs if they close their borders to fentanyl. "As far as I know, they are acting swiftly, and if they execute it, there will be no tariff," Howard Lutnick said on Wednesday during a confirmation hearing before senators.

General Motors, the largest producer of cars in Mexico, won’t provide details on how it would react if President Trump imposes 25 percent tariffs from the two countries.
