European Union leaders have issued a stark warning after U.S. President Donald Trump vowed to impose escalating tariffs on European allies unless Washington is allowed to buy Greenland, describing the threat as a move that could trigger a “dangerous downward spiral” in transatlantic relations. The remarks underline growing unease in Brussels over the direction of U.S. policy toward Europe and its potential economic and geopolitical fallout.
European Commission President Ursula von der Leyen and European Council President Antonio Costa said tariffs would undermine the foundations of cooperation between the United States and Europe, stressing that the bloc would not be coerced on matters of sovereignty. In coordinated messages, they said Europe would remain united and committed to defending its interests, signalling that the EU views Trump’s proposal not merely as a trade dispute but as a challenge to political norms governing relations among allies.
The EU’s top diplomat, Kaja Kallas, warned that tariffs would damage prosperity on both sides of the Atlantic while diverting attention from what she described as Europe’s core strategic priority: ending Russia’s war in Ukraine. She argued that trade confrontation between allies would only benefit rival powers, saying China and Russia would welcome divisions within the Western alliance.
Kallas also rejected the premise that Greenland’s security justified economic pressure, noting that any concerns could be addressed within NATO rather than through unilateral trade measures. Her comments reflect broader frustration in European capitals that Trump’s approach risks weakening collective security frameworks at a time when unity is seen as essential.
In response to the escalating rhetoric, ambassadors from the EU’s 27 member states are set to convene on Sunday for an emergency meeting to discuss possible responses to the tariff threat. Diplomats say the talks will focus on maintaining a coordinated stance, assessing potential economic impacts, and determining whether retaliatory measures or diplomatic engagement should take priority.
The dispute adds fresh strain to an already complex transatlantic relationship, with European leaders increasingly wary that trade and security issues are becoming entangled in unpredictable ways. As Brussels prepares its response, officials are seeking to project calm resolve while warning that further escalation could leave both sides economically weaker and politically divided.
