President Donald Trump's threats to impose punishing tariffs on Canada and Mexico may be part of a strategy to gain leverage ahead of new negotiations on a regional trade agreement, experts said.

While much about the threatened tariffs is still unclear, experts predict they would be bad news for all three economies, with few winners.

President Donald Trump has once again stirred the waters of international trade, reiterating his threat to impose tariffs on Canada unless certain conditions are met. In a bold move, Trump suggested that Canada could avoid these tariffs by becoming a state within the United States.
