Trump Warns of Serious Tariffs Over EU-Canada Alliance
Canada wants to build closer relationships with Europe for trade and defense.
European Commission President Ursula von der Leyen proposed a broad partnership between Canada and the European Union.
The plan could include technology, factories, military industries and Arctic projects.
Canada also applied to join a European-led defense group called the Joint Expeditionary Force.
President Donald Trump reacted angrily and warned that the United States could impose very serious tariffs.
Trump sees the proposed partnership as a threat to American trade interests.
Canada says the partnership is about building strength with Europe, not targeting another country.
It is still unclear how any special Canadian relationship with the European Union would work.
Donald Trump called a proposed EU-Canada strategic alliance “laughable” and warned of “very serious tariffs.”
European Commission President Ursula von der Leyen proposed cooperation on manufacturing, technology, defense and Arctic projects.
Canadian Prime Minister Mark Carney is seeking to diversify Canada’s trade and defense relationships away from the United States.
Canada formally applied on September 16 to join the British-led Joint Expeditionary Force, a 10-nation North Atlantic rapid-response partnership.
The European Union has no existing formal “associate member” status, leaving the proposed arrangement’s relationship with the single market unclear.
