US President Donald Trump says he may impose tariffs on countries that do not support his plan to have the United States control Greenland.

“I may put a tariff on countries if they don’t go along with Greenland, because we need Greenland for national security,” Trump said at a health roundtable at the White House.

Since Trump returned to the White House in January, he has repeatedly expressed his desire to take over Greenland, a demand Denmark and many other European nations have rejected.

The Trump administration has argued that Greenland is geographically within the North American region and insisted that the territory is vital to US security. Critics of Trump’s comments on Greenland believe the US is also interested in the island’s vast mineral wealth.

Trump’s special envoy to Greenland also said on Friday he plans to visit the Danish territory in March and believes a deal can be made.

“I do believe that there’s a deal that should ‍and ⁠will be made once this plays out,” Jeff Landry told Fox News in an interview on Friday as a bipartisan ​delegation of ‌US lawmakers was set to meet leaders of Greenland and Denmark.

“The president is ‌serious. I think he’s laid ‌the markers down. He’s ⁠told Denmark what he’s looking for, and now it’s a matter ‌of having Secretary (of State Marco) Rubio and Vice President JD ‍Vance make a deal.”
