President Trump, along with Danish Prime Minister Mette Frederiksen and Greenland Premier Jens-Frederik Nielsen, signed a new security agreement in New York during the United Nations General Assembly on Tuesday. The deal gives the U.S. broad military authority over Greenland’s airspace and territory, allowing for expansion of existing bases and establishment of additional defense areas subject to mutual approval. It also restricts non-NATO countries from establishing bases there and emphasizes collaboration among the parties amidst changing Arctic security dynamics.

Story summary
U.S. President Donald Trump claimed on Friday that Washington has reached an agreement with Denmark and Greenland, giving the U.S. permanent control over security and other needs in Greenland, starting a series of negotiations back in February. The deal reportedly bans China, Russia, and other non-NATO countries from establishing military bases or maintaining troops in Greenland, and restricts them from making sensitive investments there without express written approval from the U.S. Trump emphasized that the agreement comes at no cost to American taxpayers and will ensure complete control over Greenland’s security indefinitely. While details remain unclear, Trump sees this as a strategic move addressing national security concerns for the United States in the Arctic region. Denmark's reaction has been cautious; Prime Minister Mette Frederiksen confirmed the deal would be signed at the United Nations General Assembly next week but did not specify further terms.
