US President Donald Trump issued a stern warning on Wednesday, threatening to impose even steeper tariffs on the European Union and Canada if they collaborate to harm the US economy, according to news agency AFP. In a late-night post on his Truth Social platform, Trump declared that “large-scale tariffs far larger than currently planned” would be levied on these nations. “If the European Union works with Canada to do economic harm to the USA, large-scale tariffs, far larger than currently planned, will be placed on them both to protect the best friend that each of those two countries has ever had!” he said.
