As traders worldwide wait to see if U.S. President Donald Trump once again holds off on putting new tariffs on Canada and Mexico, the head of the U.S. Treasury Department has highlighted one potentially promising avenue for America’s neighbors.

Mexican President Claudia Sheinbaum says she hopes to speak with U.S. President Donald Trump now that he has announced plans to impose tariffs on Mexico and Canada starting Tuesday.

President Donald Trump said Thursday tariffs of 25% on Mexican and Canadian goods are set to take effect on March 4, while also threatening to impose an additional 10% on Chinese imports on the same date.
