President Trump has announced plans for tariffs on imports from China, Canada, and the EU, while threatening economic sanctions on Russia. Jamie Dimon, CEO of JPMorgan Chase, has shifted from past criticism to praising tariffs as valuable economic tools, stating they could bolster national security. Trump is set to impose a 25% tariff on Canadian and Mexican goods by February 1 and a potential 10% tariff on Chinese imports, amidst heightened international tensions. Reactions from Europe and Canada indicate readiness to retaliate, while China seeks to maintain communications.
