Trump's statement came as a response to a question from a reporter at the White House, in connection with the president signing several decrees.
Greenland is a fantastic place, and we need it to ensure international security. I'm sure Denmark will go along with it.
He said Denmark has several reasons to review its relationship with Greenland.
It has cost them a lot to have it, and the people of Greenland are not satisfied with the Danes, they like us, he said.
Opens up for talks again
The Greenlandic Prime Minister Múte Bourup Egede reiterated on Tuesday that Greenland wants to extend a hand and continue talking to the USA – but that it is ultimately Greenland that decides what happens to the island.
Other countries cannot decide what we should do, he says during a press conference in Nuuk according to the news agency Ritzau.
Already during Trump's previous term, he showed interest in buying Greenland from Denmark. Before the current takeover, he brought up the issue again and did not rule out economic sanctions or military power if he didn't get his way.
A clear no
Denmark's Foreign Minister Lars Løkke Rasmussen is not pleased.
We cannot have a world order where countries, if they are big enough, can just take what they want, regardless of what they are called, he says at a press meeting in Copenhagen on Tuesday, according to Ritzau.
An even clearer no is expressed simultaneously in a debate in the EU Parliament.
Let me say it in a way you understand, Mr. Trump: Fuck off, says Anders Vistisen, a member of the Danish People's Party.
Neither Denmark nor Greenland has expressed interest in selling the island to the USA.
