"That's enough now," Greenland's Prime Minister Jens Frederik Nielsen said after repeated threats from US President Donald Trump to annex the autonomous Danish territory.
"No more pressure. No more insinuations. No more fantasies of annexation. We are open to dialogue. We are open to discussions. But this must happen through the proper channels and with respect for international law," the head of Greenland's government wrote on Facebook late Sunday.
President Donald Trump doubled down Sunday on his claim that Greenland should become part of the United States, despite calls by Denmark's prime minister to stop "threatening" the territory.
Washington's military intervention in Venezuela has reignited fears for Greenland, which Trump has repeatedly said he wants to annex, given its strategic location in the Arctic.
While aboard Air Force One en route to Washington, Trump reiterated the goal.
"We need Greenland from the standpoint of national security, and Denmark is not going to be able to do it," he said in response to a reporter's question.
"We'll worry about Greenland in about two months... let's talk about Greenland in 20 days."
Over the weekend, the Danish prime minister called on Washington to stop "threatening its historical ally".
"I have to say this very clearly to the United States: it is absolutely absurd to say that the United States should take control of Greenland," Prime Minister Mette Frederiksen said in a statement.
She also noted that Denmark, "and thus Greenland", was a NATO member protected by the agreement's security guarantees.
