The trilateral agreement adds two defense installations, upgrades a space base and clears the way for rare earths and data center projects.
President Donald Trump signed a trilateral security agreement for Greenland this week at the United Nations alongside Denmark’s Prime Minister Mette Frederiksen and Greenland’s Prime Minister Jens-Frederik Nielsen.
The pact, known as the Arctic Security Agreement, expands the American military presence to counter Chinese and Russian ambitions in the Arctic Circle. Under the deal, the U.S. will establish two new defense bases at Narsarsuaq and Mestersvig and overhaul Pituffik Space Base, the northernmost Department of Defense installation located 750 miles north of the Arctic Circle. Construction at Pituffik is scheduled to start imminently.
Mining and data center investments
The Greenland deal bars American adversaries from setting up military bases or making sensitive investments on the island without prior U.S. approval. Greenland is a Danish territory with 55,700 inhabitants and receives annual financial support from Denmark.
U.S. Arctic Commissioner Tom Dans said the agreement allows the U.S. to look beyond defense by helping revamp infrastructure projects and bringing in additional workers. ‘When America goes to work in Greenland, things happen,’ Dans said. ‘We built the main base there, I think, in nine months. We built probably what’s the best airport and base there in six months.’
Private investment is already underway. Greenland Mines, a company based in North Carolina, bought the Sarfartoq rare earths project in southwest Greenland to mine neodymium and praseodymium for magnets. The site isn’t an operational mine yet, but a shareholder said the goal is to process the extracted materials at a facility in Estonia.
Dans said data centers are likely to follow. ‘There are groups out there working on it,’ Dans said, noting there is ‘a strong rationale’ to build where ‘you have a tremendous energy source and you have the benefit of, you know, cold climate.’ GreenMet, a Washington, D.C., firm, is planning a data center in the Kangerlussuaq area, though waiting for Danish government approval has delayed the project.
Diplomatic timing and future talks
The timing of the Trump Greenland deal coincides with Chinese President Xi Jinping’s visit to Washington on Wednesday, giving Trump leverage in discussions over national security and artificial intelligence. The agreement addresses AI supply needs by securing rare earth magnet materials and energy infrastructure, while countering arguments that the U.S. has distanced itself from Europe. ‘The animating intent is always to make ourselves and our allies stronger,’ Dans said.
Trump has sought to buy Greenland since his first term and sent representatives, including Vice President Vance, to pitch the idea to Greenlanders last year. Dans addressed the island’s status directly: ‘The Greenlanders are going to decide their future. They’ve got great friends now in the United States and Denmark’, though he noted he hasn’t ruled out closer relations.
More project proposals are expected to be unveiled at the Arctic Circle Assembly in Reykjavik, scheduled for Oct. 8-10.
