U.S. President Donald Trump announced on Saturday that the United States has reached a deal with Denmark to bolster American military presence in Greenland, a move that follows months of rhetoric about the strategic importance of the island to NATO and U.S. interests.

British Prime Minister Rishi Sunak welcomed the agreement in a call with Danish Prime Minister Mette Frederiksen on Sunday, saying the pact would benefit the United States, Greenland and Denmark and underscoring the “strategic and shared importance of the High North for Euro‑Atlantic security.”

Downing Street’s readout noted that the two leaders also discussed their upcoming trips to New York for the United Nations General Assembly, where they plan to push forward on domestic priorities such as reducing the cost of living and reinforcing security through closer international partnerships.

The forthcoming signing of the deal, scheduled for later this week, will formalise cooperation on defence and security across the Arctic and the North Atlantic, linking U.S. forces with Danish and Greenlandic authorities.

Labour leader Andy Burnham publicly congratulated Denmark and the United States on the agreement, describing it as a step to “strengthen security in the Arctic.”

In addition to the Arctic pact, Sunak and Frederiksen raised the situation in Ukraine, expressing hope for further progress on support for Kyiv during the UNGA and in the weeks ahead, and pledged to maintain close contact on the issues.

The agreement arrives amid heightened geopolitical competition in the polar region, where melting ice is opening new shipping routes and increasing the strategic value of the Arctic for both military and economic reasons.
