Trump threatened "far larger" tariffs on the EU and Canada if they cooperate to counter his trade policies, according to CNBC. The warning followed his announcement of a 25% tariff on all foreign-made cars, effective April 2nd, with additional levies on imported parts set for May. White House aide Will Scharf said the new tariffs could generate over $100 billion annually. Global markets reacted sharply, with automaker stocks falling. Analysts warn the tariffs could raise car prices by up to $10,000 and intensify inflationary pressure in the U.S.
