Donald Trump is poised to impose a 50% tariff on Canadian goods within 30 days, a move directly contradicting the trade agreement he himself negotiated with Canada and Mexico. This potential action threatens to disrupt established trade relations between the US and its North American neighbours. The tariffs signal a significant shift in Trump's approach to trade, despite previously establishing the USMCA agreement intended to foster fairer commerce. Details regarding the specific rationale behind this threat remain unclear, but it raises concerns about escalating trade tensions. According to Dagens Nyheter’s US correspondent, Björn af Kleen, this development requires careful observation. This move will likely generate strong reactions from Canada and potentially impact various sectors of the US economy.
