Denmark’s foreign minister has summoned the top U.S. diplomat in Copenhagen following intelligence assessments that U.S. citizens may have engaged in covert influence activities in Greenland, the Danish Foreign Ministry confirmed Wednesday.

Reports of Influence Efforts

According to public broadcaster DR, which cited unnamed sources, Danish authorities believe that at least three U.S. nationals with connections to the Trump administration were involved in efforts to encourage Greenland’s secession from Denmark in favor of closer ties with the United States.

Foreign Minister Lars Løkke Rasmussen said in a statement that Denmark remains vigilant about foreign interest in Greenland.

“We are aware that foreign actors continue to show an interest in Greenland and its position in the Kingdom of Denmark. It is therefore not surprising if we experience outside attempts to influence the future of the Kingdom in the time ahead,” Rasmussen said.

Neither the Danish government nor DR identified the individuals allegedly connected to the activities. The U.S. Embassy in Copenhagen has not publicly commented.

U.S. Position on Greenland

Greenland is a self-governing territory within the Kingdom of Denmark, valued for its strategic Arctic location and natural resources. Trump previously stated that he favored U.S. control of Greenland for national security and economic reasons, a proposal firmly rejected by both Denmark and Greenland’s government in Nuuk.

Although Trump later emphasized respect for Greenland’s right to determine its own future, earlier remarks about potentially using force contributed to unease among the island’s roughly 57,000 residents.

Diplomatic Context

Denmark has sought to strengthen ties with Greenland and build broader European support for its role in the Arctic. In June, French President Emmanuel Macron visited Greenland in a show of solidarity, drawing large crowds. By contrast, U.S. Vice President JD Vance’s visit in March was met with protests, limiting his trip to a U.S. military base and altering planned events.

Intelligence Assessment

Denmark’s domestic security and intelligence service (PET) said in a statement that Greenland remains a target for various influence campaigns.

“This could be done by exploiting existing or invented disagreements … or by promoting or reinforcing certain views in Greenland regarding the Kingdom of Denmark and the United States or other countries with a special interest in Greenland,” PET said.

The U.S. Embassy in Copenhagen is currently led by Chargé d’affaires Mark Stroh. Trump recently appointed PayPal co-founder Ken Howery to serve as the next U.S. ambassador to Denmark, though he has not yet assumed the post.
