Denmark, its autonomous territory of Greenland, and the United States are scheduled to sign a new Arctic security agreement in New York on Tuesday, September 22, 2026. The signing ceremony will take place on the sidelines of the UN General Assembly, according to a statement from the Danish Prime Minister’s Office.

The agreement will be signed by Greenland’s Prime Minister Jens-Frederik Nielsen, Danish Prime Minister Mette Frederiksen, and US President Donald Trump. The statement did not disclose the specific terms of the pact but said it aims to strengthen security in the Arctic and North Atlantic region.

President Trump announced the deal on social media last Friday, stating it would grant the United States “permanent control” over Greenland’s security. In response, Prime Minister Frederiksen emphasized that the agreement recognizes the Kingdom of Denmark’s sovereignty and territorial integrity, as well as the right to self-determination for the people of Greenland.

The new pact builds upon a longstanding defense agreement between Denmark and the US, originally signed in 1951 and amended in 2004, which already grants the US military broad authorization to maintain personnel and facilities in Greenland, including the strategic Pituffik Space Base.
