Ankara, Turkey - Danish Prime Minister Mette Frederiksen on Wednesday held firm against a renewed suggestion by President Donald Trump that Greenland "should be controlled by the United States."

Asked by reporters to comment on Trump's latest remarks when arriving for consultations at the NATO summit in Ankara, Frederiksen stressed that the island administered by the Kingdom of Denmark was "not for sale."

"We hope that all, including all allies, will respect the Greenlandic people's right for self-determination. And we are a sovereign state, and we need everybody to respect our territorial integrity and our sovereignty," she added.

On Tuesday, Trump reiterated that Greenland "should be controlled by the United States, not by Denmark," stressing that the vast and strategically important Arctic territory was surrounded by Chinese and Russian ships.

Earlier this year, Trump openly threatened to take over Greenland, not only alienating NATO ally Denmark but also raising doubts about the cohesion of the world's largest military alliance. His justification was that the territory belonging to Denmark would otherwise not be safe from Russia and China and was therefore a problem for US security interests.

Trump later withdrew the threat to use military means if necessary and dropped the announcement of punitive tariffs against European countries if they did not agree to sell the island to the US. However, he stuck to his claims to the island.

The governments of Denmark and Greenland have consistently rejected US annexation.

Noting that Denmark had previously countered his bid to acquire Greenland despite "all the money we spent to help them with Russia," Trump again floated the possibility at the NATO summit of withdrawing all US troops stationed in Europe.

NATO Secretary General Mark Rutte, who previously mediated in the dispute, said the alliance had "a good process in place" regarding Denmark and Greenland.

In February, Denmark, Greenland, and the US started talks on a potential future agreement on ensuring security in the Arctic through joint actions by the US and Arctic allies. In addition, allies enhanced their presence in Greenland.

Rutte stressed that Trump remained "completely committed" to NATO despite differences over Greenland, defense spending, and the war in Iran.

Nordic NATO allies rallied behind Copenhagen on Wednesday, stressing that it was for Greenland and Denmark to determine the territory's future.

Icelandic Prime Minister Kristrún Frostadóttir said that "Greenland belongs to the people of Greenland. They do not wish to be a part of the United States."

"What we need now is unity. We have threats coming from outside the alliance," she said, pointing to Russia. "We need to focus on us and how we stick together."

Finnish President Alexander Stubb stressed that "matters of Greenland are linked and only in the hands of the Kingdom of Denmark."

Noting that discussions were being held between the US, Denmark, and Greenland, Stubb added that several NATO countries, including Finland, had "Arctic know-how" that could help to secure the region.
