WASHINGTON

US President Donald Trump said Monday he had a "very good" phone call with NATO Secretary-General Mark Rutte concerning Greenland.

"I agreed to a meeting of the various parties in Davos, Switzerland. As I expressed to everyone, very plainly, Greenland is imperative for National and World Security. There can be no going back — On that, everyone agrees!" Trump said on Truth Social.

Trump has said that the US must acquire Greenland for national security reasons and to deter rivals in the Arctic. He has also threatened tariffs on European allies who opposed US control of Greenland and sent a small of number of troops to the territory.

Both Denmark and Greenland have rejected any proposal to sell the territory.
