U.S. President Donald Trump called off an upcoming trip to Denmark after its prime minister rebuffed his interest in buying Greenland, a Danish territory, the White House announced Tuesday.

“Denmark is a very special country with incredible people, but based on Prime Minister Mette Frederiksen’s comments, that she would have no interest in discussing the purchase of Greenland, I will be postponing our meeting scheduled in two weeks for another time,” Trump tweeted.

Trump was invited on an official state visit by the Queen of Denmark. White House Deputy Press Secretary Judd Deere confirmed later Tuesday the entire trip was off.

Trump mused about acquiring Greenland from Denmark on Sunday, telling reporters that “it’s something we talked about.”

But, he added, “first we have to find out whether or not they have any interest.”

Frederiksen said they did not.

“Greenland is not for sale,” she told Greenlandish media Sunday. “Greenland is not Danish. Greenland belongs to Greenland. I strongly hope that this is not meant seriously.”
