Mexican President Claudia Sheinbaum on Tuesday warned U.S. President-elect Donald Trump of dire economic consequences for both countries from tariffs and suggested possible retaliation following his threat of across-the-board tariffs of 25% on Mexico and Canada.

Mexican President Claudia Sheinbaum has clapped back at President-elect Trump’s proposed 25% tariff on imported goods from Mexico, saying she would impose tariffs of her own on the U.S.

President-elect Donald Trump said he would impose the import tariffs — 25 percent for Canada and Mexico and 10 percent for China — as soon as he takes office.
