Greenland’s leaders rejected US ownership in January 2026 while supporting security cooperation with allies. A later development changed the diplomatic picture: on 22 September, Greenland, Denmark and the United States signed an Arctic security agreement. This timeline separates the January response to Donald Trump’s takeover proposals from that September agreement.
6 January: European leaders set out their position
A joint statement from the leaders of Denmark, France, Germany, Italy, Poland, Spain and the United Kingdom said decisions concerning Greenland belonged to Greenland and Denmark. It called for collective Arctic security with NATO allies, including the United States, while respecting sovereignty and borders.
The statement identified the Kingdom of Denmark, including Greenland, as part of NATO and referred to the 1951 defence agreement with the United States.
13 January: Greenland rejects US ownership
At a joint press conference with Danish Prime Minister Mette Frederiksen, Greenland’s Prime Minister Jens-Frederik Nielsen said Greenland was not for sale and did not want to be owned or governed by the United States. He said that, if required to choose between Denmark and the United States at that moment, Greenland would choose Denmark.
Nielsen also expressed support for peaceful cooperation, international law and Greenland’s right to determine its future. His statement distinguished opposition to a takeover from willingness to maintain an alliance.
22 September: A security agreement is signed
The Danish Prime Minister’s Office announced that Nielsen, Frederiksen and Trump signed an agreement at the United Nations headquarters in New York. Its announcement described stronger Arctic and North Atlantic security cooperation and recognition of the Kingdom of Denmark’s sovereignty and territorial integrity, alongside Greenlandic self-determination.
The same announcement said entry into force depended on the necessary national parliamentary procedures. Signing and entry into force should therefore be treated as separate steps; this article does not establish that those procedures have finished.
How to read the takeover headlines
The January statements explain the rejection of US ownership. The September announcement concerns an agreed security relationship. Reading the documents in date order avoids presenting an old dispute as an unchanged breaking-news event or assuming that a signing ceremony completes every implementation step.
