After Wednesday's decision on 25-percent tariffs on vehicles and vehicle components manufactured outside the USA, the President of the European Commission, Ursula von der Leyen, regretted the decision.
She also said that the union will continue to seek solutions through negotiations, while "defending its economic interests".
Canada's Prime Minister Mark Carney reacts with anger to the introduction of import tariffs on cars and calls it a "direct attack" on his country, reports AFP.
There have been no reports or statements indicating that the EU and Canada plan to act jointly against the tariffs, but in a post on his social media platform Truth Social, Donald Trump joins in and warns the two countries.
"If the European Union collaborates with Canada to inflict economic harm on the USA, high tariffs, much higher than what has been planned so far, will be introduced against them to protect the best friend any of them has ever had", writes Trump.
