最新报道:Dow Jones Industrial Average fell over 250 points as former President Donald Trump proposed a 35% tariff on goods from Canada if re-elected. The market reacted negatively to the potential trade barrier, with investors concerned about renewed tensions between the U.S. and its northern neighbor. The tariff threat comes amid ongoing economic uncertainties and could impact cross-border supply chains. Analysts warn such protectionist measures may disrupt North American trade flows and corporate earnings. The proposal follows Trump's previous trade confrontations with Canada during his presidency.
