Greenland's PM Jens Frederik Nielsen firmly rejected US President Trump's repeated comments on US possibly annexing Greenland, asking for dialogue and respect for international law.

Axar.az informs, citing Euronews, "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, Nielsen wrote on Facebook late Sunday.

"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 said.

Washington's unprecedented operation in Venezuela resulting in the capture of Nicolas Maduro has reignited fears for Greenland, which Trump has said he wants to annex, given its strategic location in the Arctic.

On Sunday, Trump doubled down on his claim that Greenland should become part of the United States, despite calls by the leaders of Denmark and Greenland — the Kingdom of Denmark's autonomous territory — to stop "threatening" the territory.
