Danish PM tells US: 'You cannot annex another country'

Denmark's prime minister has said that Copenhagen would not give up Greenland, telling the United States that "you cannot annex another country".

Mette Frederiksen made the comments in English as she visited the resource-rich autonomous Danish region that US President Donald Trump has vowed to take over.

In the capital Nuuk, Ms Frederiksen met her Greenlandic counterpart Jens-Frederik Nielsen as well as Mr Nielsen's predecessor Mute Egede.

The trio boarded a Danish navy patrol vessel called Vaedderen for a trip around Nuuk.

Danish public broadcaster DR said many people expressed joy at seeing Ms Frederiksen, with one resident shouting from a window: "Hey Mette! Thanks for being here."

Tensions between the United States and Denmark have soared after Mr Trump repeatedly said he wanted to take control of the resource-rich Arctic island for security reasons.

"It is clear that with the pressure put on Greenland by the Americans, in terms of sovereignty, borders and the future, we need to stay united," Ms Frederiksen said after arriving on the island for a three-day visit.

Her visit comes on the heels of a trip by US Vice President JD Vance last week that both Greenland and Denmark viewed as a provocation.

It also follows the formation of a new Greenland coalition government led by the centre-right Democrats party, which won a general election in March.

"I have but one wish and that is to do all that I can to take care of this marvellous country and to support it at a difficult time," the Danish prime minister said.

Observers say her visit will reassure the island of 57,000 people, the vast majority of whom, polls show, want to become independent from Denmark but do not wish to become part of the United States.

"I think it's very, very important and it's very reassuring for Greenlanders to see a Danish head of government," Mikaela Engell, an expert on the Arctic territory who previously served as Denmark's High Commissioner to Greenland, told AFP.

Earlier this year, "the Danish government was almost invisible," she said, describing Copenhagen's efforts as tip-toeing, trying to accommodate US interests and not antagonise Mr Trump.

But after the general election and Mr Vance's visit, the "gloves have come off," Ms Engell said.

Marc Jacobsen, a researcher at the Royal Danish Defence College, told AFP that the visit would give Denmark an opportunity "to show coherence, to show support, to talk about what can they do more concretely, both in terms of how to respond to the United States, but also in terms of concrete cooperation investments".

Ms Frederiksen is also expected to maintain the position laid out earlier by Denmark's foreign minister "that it is possible to enhance US military presence" under a 1951 defence agreement.

During his visit last week to the Pituffik military base, Mr Vance castigated Denmark for not having "done a good job by the people of Greenland" by allegedly under investing in security.

Foreign Minister Lars Løkke Rasmussen responded in a post on social media that Denmark is "open to criticisms, but let me be completely honest, we do not appreciate the tone in which it's being delivered".

Denmark's foreign ministry has said efforts are under way to set up a meeting between Mr Rasmussen and his US counterpart Marco Rubio at a meeting of NATO foreign ministers this week in Brussels, but "neither Greenland nor the Arctic are planned to be discussed".

"It will be the elephant in the room, right?" Mr Jacobsen said.

"But the thing is that if they were to talk about the Arctic and Greenland, then someone from the Greenland government should be present, that's the agreement between Denmark and Greenland," he added.

According to The Washington Post, the White House is currently estimating the cost for the US federal government to control Greenland and the potential revenues it could derive from exploiting its largely untapped natural resources.
