General Mark Rutte and Danish Prime Minister Mette Frederiksen agreed at a meeting on Tuesday that allies need to focus on strengthening defences in the Arctic, a source familiar with the talks told Reuters.

The Secretary-General of NATO, Mark Rutte, and the Prime Minister of Denmark, Mette Frederiksen, have agreed on the need to strengthen defenses in the Arctic, according to a Reuters source knowledgeable about the discussions.

Trump has refused to rule out using military coercion to secure a deal to buy the island, which is Danish territory.

Denmark said Monday, January 27, that it would spend 14.6 billion kroner ($2 billion) to bolster security in the strategic Arctic region near the United States and Russia. The announcement came after US President Donald Trump said he would "get Greenland," adding the autonomous Danish territory is needed for his country's "international security."

Denmark has unveiled plans to allocate around DKr14bn (equivalent to $1.96bn) for the enhancement of its military capabilities in the Arctic and North Atlantic territories. The consensus on this allocation was reached by the political parties including the Greenlandic and Faroese Governments that support the 2024-2033 Danish Defence Agreement.

Denmark's defense minister has announced a deal with the governments of the Faroe Islands and Greenland to boost surveillance capacity and sovereignty assertion. The move comes as the US, Russia and China circle.
