Trump says US reached 'infinite' security deal with Denmark over Greenland

US President Donald Trump said Friday that he had struck a deal with Denmark to give Washington "permanent control" over Greenland's security that would bar Russia and China from setting up bases in the Arctic territory.

Since returning to the White House in January 2025, Trump has repeatedly argued that the US needs control of Greenland for strategic reasons, raising concerns in NATO ally Denmark and drawing strong opposition from the alliance.

Denmark and Greenland -- an autonomous territory controlled by Copenhagen -- both hailed the deal and said they would sign it on the sidelines of the UN General Assembly in New York next week.

"I am pleased to announce that the United States of America has entered into an Agreement with The Kingdom of Denmark, and Greenland, that gives the United States permanent control over security, and all other needs, in Greenland," Trump said on his Truth Social network.

"From now on, no US adversary can EVER have a base in Greenland, have a military presence in Greenland, or make sensitive investments in Greenland, without our express written approval."

The 80-year-old said it was an "'Infinite Life' Agreement, there is no end!" and said Washington would immediately start building up a large military presence in the territory.

'Good agreement'

Trump has repeatedly warned about Russia and China trying to establish a foothold in Greenland amid a strategic battle for supremacy in a warming Arctic, and the State Department left no doubt that they would not be allowed to do so.

"This agreement guarantees that China and Russia cannot have a base in Greenland, they cannot send troops to Greenland, and the necessary mechanisms are in place to prevent investment in sensitive sectors," a State Department official said.

At the Davos economic forum this past January, Trump reached a purported deal with NATO Secretary General Mark Rutte over the future of Greenland, the terms of which have remained vague.

Danish Prime Minister Mette Frederiksen had said Monday that she was "optimistic" that ongoing discussions with the United States and Greenland since January could resolve the dispute.

On Friday, she said she was "pleased that there is a prospect of a good agreement for Greenland, the Kingdom of Denmark and the United States," adding that it was "good for NATO and Europe."

Greenland Prime Minister Jens-Frederik Nielsen said the deal with the United States "strengthens" the territory's security.

NATO tensions

Trump gave no details about how the deal would work, and it was not clear if it was linked to or substantially different from the Rutte deal.

But several media outlets have reported that the United States wants to open three new military bases in southern Greenland, in addition to the Pituffik base it already has in the north of the territory.

A 1951 defense pact, updated in 2004, already allows Washington to ramp up troop deployments and military installations on the island provided it informs Denmark and Greenland in advance.

At the height of the crisis, Trump would not rule out using force to seize the territory of 57,000 inhabitants, sowing anxiety within the EU and NATO.

Since then, tensions have cooled somewhat, and in an apparent move to assuage Trump, NATO launched a new mission to bolster security in the Arctic.
