Stocks were mixed in early trading on Monday after President Donald Trump over the weekend issued 30% tariffs on the European Union and Mexico, rekindling tensions with two of the largest U.S. trade partners and threatening to raise consumer prices.

President Donald Trump has announced he’s levying tariffs of 30% against the European Union and Mexico starting Aug. 1.

Mexican President Claudia Sheinbaum on Tuesday said Mexico will take action if an agreement with Washington regarding new tariffs is not reached by the August 1 deadline set by her U.S. counterpart Donald Trump.

President Donald Trump posted letters to the leaders of Mexico and the European Union, saying they had not done enough to head off the new tariffs.

America’s biggest trading partners have tried tactics ranging from appeasement to retaliation to avoid higher tariffs. All find themselves faced with similar threats from Washington.

Indonesia also received a letter from Trump last week outlining plans for a 32% tariff on its goods, reportedly bewildering officials who had thought a deal was close. Trump said

The European Union could target Boeing and whiskey-maker Brown-Forman under its plans for retaliatory tariffs if the bloc can’t reach a trade deal with the U.S.

President Trump set a 50 day deadline for a ceasefire deal between Russia and Ukraine or else he will hit Russia with "severe" tariffs. Also, the U.S. is sending weapons to Ukraine through NATO.
