Greenland’s Prime Minister Jens-Frederik Nielsen has issued a warning to the United States to cease its annexation threats toward the territory. In a statement on Sunday, he declared, “No more pressure. No more hints. No more fantasies about annexation,” stressing that while Greenland remains open to dialogue with the U.S., it will no longer tolerate “pressure” or “disrespectful posts on social media.” Nielsen’s forceful remarks come as President Donald Trump renews his annexation threats against Greenland following the operation that resulted in Nicolás Maduro being captured and transported to the U.S.

In remarks that Nielsen called “utterly unacceptable,” Trump reiterated his desire to pursue U.S. annexation of Greenland, an autonomous territory within the Kingdom of Denmark. “We need Greenland from a national security situation. It’s so strategic,” the President told reporters aboard Air Force One over the weekend. “Right now Greenland is covered with Russian and Chinese ships all over the place. We need Greenland from the standpoint of national security. And Denmark is not going to be able to do it.” Trump asserted that the European Union “needs” the U.S. to “have” Greenland. (European leaders have defended Greenland against Trump’s annexation threats.)

“When the President of the United States talks about ‘we need Greenland’ and connects us with Venezuela and military intervention, it’s not just wrong, it’s so disrespectful,” Nielsen said in his social media response. Addressing Trump’s rhetoric concerning Greenland’s position, Nielsen added: “We are a part of NATO and we are fully aware of our country’s strategic location. And we realize that our security depends on good friends and strong alliances. In this regard, a respectful and loyal relationship with the United States is very important. It’s been that way for decades.”

Trump has repeatedly voiced his wish for Greenland to join the U.S. since returning to the White House last year. During a May interview with NBC’s Meet the Press, he expressed his intention to annex the territory.

Now, as Trump intensifies his threats, others in the MAGA circle have weighed in on the issue. Katie Miller, wife of Trump’s deputy chief of staff for policy Stephen Miller, hinted at future U.S. control of Greenland in a weekend social media post. She wrote “soon” alongside an image of a Greenland map overlaid with the U.S. flag.

Nielsen replied, “our country is not for sale and our future is not determined by social media posts.” He encouraged Greenland’s residents not to panic, but maintained “there’s good reason to speak up against the lack of respect.”

Greenland’s residents elected Nielsen as Prime Minister in March of last year. The election was widely viewed as a rebuke to the annexation threat, as Nielsen campaigned in opposition to Trump’s desire for a U.S. takeover.

Shortly after Nielsen’s victory, Vice President J.D. Vance visited American troops at the Pituffik Space Base in Greenland. “Our message to Denmark is very simple: You have not done a good job by the people of Greenland,” Vance told the U.S. personnel.

In August, the top U.S. diplomat in Copenhagen was summoned by the Danish Foreign Minister following reports that three Americans close to the President had been compiling names of Greenland citizens interested in joining a secessionist movement.

Denmark’s Foreign Minister Lars Løkke Rasmussen confirmed to TIME that he had summoned Mark Stroh, the U.S. charge d’affaires in Copenhagen, and declared “any attempt to interfere in the internal affairs of the Kingdom [of Denmark] will of course be unacceptable.”

Tensions escalated again in December when Trump appointed Louisiana Gov. Jeff Landry as special envoy to Greenland. “Jeff understands how essential Greenland is to our national security, and will strongly advance our country’s interests for the safety, security, and survival of our allies, and indeed, the world,” Trump said of his decision.
