US President Donald Trump has called the Danish leader “nasty” after she rebuffed his idea of buying Greenland.
He lashed out hours after Prime Minister Mette Frederiksen said she was “sorry” that Mr Trump had abruptly called off a state visit to Denmark.
She has dismissed the suggestion of such a land deal as “absurd”.
Queen Margrethe II invited Mr Trump to visit Denmark on September 2, and the manner of his cancellation has stunned the Scandinavian nation.
What did the US president say?
Speaking to reporters on the White House lawn on Wednesday afternoon, Mr Trump took umbrage at Ms Frederiksen’s remarks.
“I thought that the prime minister’s statement that it was absurd, that it was an absurd idea was nasty,” he said.
“I thought it was an inappropriate statement. All she had to do is say no, we wouldn’t be interested.”
He added: “She’s not talking to me. She’s talking to the United States of America. You don’t talk to the United States that way, at least under me.”
Mr Trump pointed out that US President Harry Truman once considered making an offer for Greenland, which is an autonomous Danish territory.
He continued to make digs at Denmark online.
What did the Danish PM say?
Earlier on Wednesday, Ms Frederiksen reiterated that Greenland could not be bought.
She told reporters the idea of selling the resource-rich Arctic island had “clearly been rejected” by its leader, Kim Kielsen, “a position I share of course”.
Ms Frederiksen also said the American president’s visit would have been an “opportunity to celebrate Denmark’s close relationship to the US”.
“This does not change the character of our good relations and we will continue our dialogue on how we can deal with challenges we are facing,” she said, adding that the invitation to Mr Trump “remains open”.
She has said Mr Trump’s no-show was a matter of regret because “our preparations were well under way”.
