Denmark's Prime Minister Mette Frederiksen said on Friday that Denmark and Greenland will sign a security agreement with the United States at the UN General Assembly next week. The deal will allow the U.S. permanent control over Greenland's security and bar foreign adversaries from establishing bases there.
Frederiksen called the pact "good for NATO and Europe" and said it would strengthen common security in the Arctic and North Atlantic. The agreement also recognises Denmark's sovereignty and Greenlandic self‑determination.
U.S. President Donald Trump posted on Truth Social that the agreement grants Washington "infinite" control over Greenland's security. He warned that no U.S. adversary could set up a base without written approval.
Jens‑Frederik Nielsen, head of Greenland's government, welcomed the deal, saying it recognises Greenland's interests and its place in international cooperation—an endorsement that could ease tensions with NATO allies.
Once signed, the agreement will undergo parliamentary scrutiny before taking force, according to a statement from Frederiksen's office. The Danish parliament is slated to vote on the treaty in early June.
The deal is expected to be signed on the sidelines of the UN General Assembly in New York on Monday, with a vote in the Danish parliament slated for early June.
