Jan. 17 (UPI) -- Eight NATO member nations will be subjected to tariffs if they don't remove recently deployed troops from Greenland, President Donald Trump said.

Denmark, Finland, France, Germany, the Netherlands, Norway, Sweden and the United Kingdom will be assessed 10% tariffs as of Feb. 1, which would more than double to 25% on June 1, if they do not remove their troops from Greenland, Trump said Saturday.

Greenland is a territory owned by Denmark, which Trump wants to make part of the United States for military purposes and says will be occupied by China or Russia if it does not become a U.S. territory.

"World Peace is at stake!" Trump said in a post on Truth Social. "China and Russia want Greenland, and there is not a thing that Denmark can do about it."
