Mexico said it would slap tit-for-tat tariffs on the US, while China said Trump's finger-pointing "runs completely counter to facts".

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.

President Claudia Sheinbaum suggested Tuesday that Mexico could retaliate with tariffs of its own, after U.S. President-elect Donald Trump threatened to impose 25% import duties on Mexican goods if the country doesn't stop the flow of drugs and migrants across the border.
