During President-elect Donald Trump’s first term, America launched an all-out trade war with China to boost US manufacturing, secure US national security interests and resolve what Trump believed was an extremely out-of-balance trade relationship.

Mexico and Canada are two of America's biggest trading partners, shipping everything from energy and vehicles to machinery and electronics to the US.

The governments of China and Mexico warned of retaliatory trade actions and Canada urged restraint Tuesday after President-elect Trump on Monday threatened steep tariffs to pressure those countries into cracking down on drug trafficking and illegal immigration.
