European Union leaders and the United Kingdom have mounted a robust diplomatic response to United States President Donald Trump’s announcement that he would impose tariffs on several European and NATO allies over their opposition to American efforts to secure Greenland.

Trump’s plan envisaged a ten per cent tariff on goods from Denmark, Norway, Sweden, France, Germany, the Netherlands, Finland and the UK starting in February and rising to twenty-five per cent by June if no agreement on US control of Greenland is reached.

His administration framed the tariffs as leverage in negotiations on the future of the strategic Arctic territory.

European Union ambassadors convened an emergency meeting in Brussels to coordinate a response, condemning the threatened tariffs as “completely wrong” and warning that using trade tools against allies risks a “dangerous downward spiral” in transatlantic relations.

The bloc’s leadership reaffirmed its commitment to Denmark’s sovereignty over Greenland and underscored the importance of international law and allied unity.

European Council President António Costa called for unity and a firm defence of shared principles, while European Commission President Ursula von der Leyen emphasised that the EU would remain united and prepared to employ defensive trade measures, including the bloc’s anti-coercion instrument and possible retaliatory tariffs on US imports worth billions of euros.

The UK government echoed these sentiments, with British Prime Minister Keir Starmer characterising Trump’s tariff threats as “completely wrong” and urging calm diplomatic engagement.

London has stressed that decisions about Greenland’s future must be left to Denmark and Greenland’s people, not external pressure.

Starmer reiterated the importance of collective NATO security and warned that punitive trade measures among allies undermine shared interests.

UK officials said they would pursue dialogue with Washington while coordinating with European partners on a measured response.

Across Europe, leaders have also signalled readiness to explore a range of responses, from potential retaliatory tariffs to legal challenges and shifts in trade negotiations.

The European Parliament has paused ratification of a key EU–US trade agreement in light of the dispute, illustrating the depth of concern over the use of tariffs as leverage.

At the same time, national leaders emphasise that their response aims to protect transatlantic cooperation while upholding the territorial integrity of Greenland within the Kingdom of Denmark.
