“I’m not going to give up options, but this is very important. Greenland is very important to national security, including Denmark’s national security,” Trump said during an event in the Oval Office. “The problem is that there is nothing Denmark can do about it if Russia or China want to occupy Greenland, but there is everything we can do.”

The president’s comments came after the foreign ministers of Denmark, a NATO member state, and Greenland, a semi-autonomous Danish territory, met earlier in the day with Vice President J.D. Vance and Secretary of State Marco Rubio in Washington.

After the meeting, Danish Foreign Minister Lars Løkke Rasmussen told reporters that the United States and Denmark “still have a fundamental disagreement,” but that they would form a working group to “explore whether we can find a common way forward.”
