Trump has wanted a foothold in Greenland for some time, as a strategic battle unfolds for supremacy in a warming Arctic.

Denmark has hailed a “binding” deal by United States President Donald Trump to give Washington “permanent control” over Greenland’s security and bar Russian and Chinese military bases from the Arctic territory.

But Denmark and Greenland – an autonomous Danish territory – said on Saturday that any deal with the US would not compromise Greenland’s sovereignty, and the two countries would sign the agreement next week at the United Nations General Assembly in New York.

“A long period of uncertainty will hopefully be replaced by a binding agreement that strengthens security in the Arctic and North Atlantic, and thereby our shared security within NATO and Europe – while respecting the [Danish] Kingdom’s red lines,” Danish Foreign Minister Lars Lokke Rasmussen said in a social media post.

Since returning to the White House in January 2025, Trump has repeatedly insisted that Washington needed to control Greenland for strategic reasons, alarming NATO ally Denmark and sparking fierce pushback from the alliance.

Key details of the agreement ⁠have not been made public, including the scale of the US military presence in the self-governing Danish territory and whether any formal power over foreign policy and resources would be ceded to Washington.

Greenland’s Prime Minister Jens-Frederik Nielsen said the agreement “recognises Greenland’s interests” and is “to the benefit of us all”.

Denmark’s Prime Minister Mette Frederiksen said it is “great for NATO and Europe”, as it “strengthens our common security in the Arctic and the North Atlantic Area”.

‘I have mixed feelings’

But in Greenland’s capital Nuuk, residents had mixed feelings.

“I don’t know exactly what the agreement is or what has been signed. But whenever the US and Trump are mentioned, I have mixed feelings. I’m not entirely comfortable with how much attention Greenland has right now,” Soren Kreutzmann, a 29-year-old hairdresser, told the AFP news agency.

“We hope the leaders have made a good agreement, because our country needs to be protected, both from the air and sea. Denmark had not given that enough attention for many years,” said Bibbi Kleist Jepsen, a 64-year-old educator.

Trump, who had previously said the US needs “ownership” of Greenland, announced that Washington would immediately start building up a large military presence in the territory.

“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”, he said.

Trump has repeatedly warned of Russia and China trying to establish a foothold in Greenland as a strategic battle unfolds for supremacy in the warming Arctic region. 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.
