The deal is set to be signed next week during the UN General Assembly but requires parliamentary approval by both Danish and Greenlandic governments.

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.
