U.S. President Donald Trump said on Thursday that he had secured permanent and unrestricted U.S. access to Greenland under a framework agreement with NATO, as the alliance’s leadership urged member states to strengthen their commitment to Arctic security in response to perceived threats from Russia and China. The announcement came as Trump eased earlier tariff threats and ruled out the use of force to take control of Greenland, easing tensions that had threatened to become the most serious rupture in transatlantic relations in decades. However, the details of the proposed agreement remain unclear, and Denmark reiterated that its sovereignty over Greenland is not open for negotiation. Denmark’s foreign ministry did not immediately respond to requests for comment on Trump’s remarks. Trump’s reversal helped trigger a rebound in European markets but also raised concerns about the longer-term impact on transatlantic relations and business confidence. “It’s really being negotiated now, the details of it. But essentially it’s total access — there’s no end, there’s no time limit,” Trump told Fox Business Network in an interview from Davos, where he is attending the World Economic Forum. NATO Secretary General Mark told Reuters in Davos that responsibility now lies with the alliance’s senior military leadership to determine the additional security measures required in the Arctic. “I have no doubt we can do this quite fast. Certainly I would hope for 2026 — and possibly even early 2026,”said. Denmark Says Situation Remains Sensitive Trump’s earlier push to take sovereignty over Greenland from fellow NATO member Denmark had threatened to destabilize the alliance that has underpinned Western security since World War II and risked reigniting a trade conflict with Europe. Danish Prime Minister Mette Frederiksen said no discussions had taken place with NATO regarding Greenland’s sovereignty, which she stressed remains under Danish control as a semi-autonomous territory. “It is still a difficult and serious situation,” Frederiksen said. “But progress has been made in the sense that we can now focus on how to strengthen our shared security in the Arctic region.”
