U.S. President Donald Trump on Friday suggested that countries could face tariffs if they do not support U.S. control over Greenland, as a bipartisan Congressional delegation met in Copenhagen to ease tensions over the issue.
Trump has repeatedly asserted that the U.S. should have control over Greenland, a semiautonomous territory of NATO ally Denmark, calling any outcome short of U.S. ownership “unacceptable.” Speaking at a White House event on rural health care, Trump said he had previously threatened European allies with tariffs on pharmaceuticals and added, “I may do that for Greenland too… because we need Greenland for national security.”
This marks the first time Trump mentioned tariffs as a possible means to assert control over the Arctic territory. Earlier this week, Denmark’s and Greenland’s foreign ministers met in Washington with U.S. Vice President JD Vance and Secretary of State Marco Rubio, resulting in the formation of a working group, though disagreements between Denmark and the White House remain. Denmark has emphasized that decisions on Greenland are a matter for Denmark and Greenland and announced plans to strengthen its military presence on the island.
In Copenhagen, U.S. senators and representatives met with Danish and Greenlandic officials, including Danish Prime Minister Mette Frederiksen. Sen. Chris Coons, a Delaware Democrat, thanked Denmark for “225 years of being a good and trusted ally” and highlighted discussions on sustaining the relationship. Alaska Republican Sen. Lisa Murkowski said the visit underscored the importance of viewing Greenland as an ally rather than an asset, contrasting with the White House’s more confrontational tone.
Trump has justified his push for U.S. control by citing potential Chinese and Russian interest in Greenland, which contains vast reserves of strategic minerals, and the White House has not ruled out forceful acquisition. Aaja Chemnitz, a Greenlandic politician in the Danish parliament, said the U.S. has been the main source of threats, while Murkowski noted that public opinion strongly opposes U.S. annexation, with about 75% against it. She and Sen. Jeanne Shaheen have introduced bipartisan legislation barring the use of U.S. funds to seize Greenland or any NATO ally’s territory without consent.
The debate has sparked concern among Greenlanders. Greenlandic Prime Minister Jens-Frederik Nielsen affirmed the territory’s allegiance to Denmark, NATO, and the EU. Sara Olsvig, chair of the Inuit Circumpolar Council, criticized the U.S. stance, saying it shows a troubling view of Indigenous peoples and smaller nations, emphasizing that Greenlanders do not want to be colonized again.
