Denmark’s prime minister has told the U.S. during a visit to Greenland that “you cannot annex another country,” even with the argument that international security is at stake.

The United States and Denmark offered drastically different perspectives regarding a meeting on the sidelines of the NATO conference happening in Brussels. Secretary of State Marco Rubio met with Danish Foreign Minister Lars Løkke Rasmussen in Brussels on Thursday amid the NATO foreign ministers’ meeting.

Denmark will not give up Greenland to the US, Danish Prime Minister Mette Frederiksen has said during an official visit to the Arctic Island.Responding to repeated threats from Donald Trump, Frederiksen offered closer collaboration on security but told the US president: "You can't annex other countries.

Danish Prime Minister Mette Frederiksen called Thursday for increased Arctic defense collaboration with the United States during a visit to Greenland, and firmly dismissed the US desire to annex the semi-autonomous Danish territory.

Danish Prime Minister Mette Frederiksen is in Greenland for a three-day trip aimed at building trust and cooperation with Greenlandic officials at a time when the Trump administration is seeking control of the vast Arctic territory.

Trump has dreams of Greenland. But the semiautonomous territory of Denmark wants no part of it.

Denmark’s prime minister vowed she would not surrender Greenland to the US as she visited the autonomous Danish territory that Donald Trump wants to take over.

Denmark’s top diplomats stood up to US President Donald Trump over his encroachment on Greenland, effectively ending a policy of quiet diplomacy they had hoped would make the issue go away.

Mette Frederiksen's visit comes just days after Vice President JD Vance toured the U.S. Pituffik Space Base in Greenland.
