European leaders reacted quickly, labeling the idea of punitive duties “unacceptable” and pledging support for Denmark. Copenhagen retains authority over Greenland’s foreign affairs, defense and security, while the island’s elected government manages domestic matters. In statements released over the weekend, several European officials emphasized solidarity with the Danish realm and warned that any economic coercion aimed at forcing policy changes regarding Greenland would face a coordinated response.
Protest March in Nuuk
Public anger in Greenland became visible on Saturday when crowds gathered in Nuuk, a city of roughly 19,000 residents, to denounce Washington’s latest overtures. Nielsen joined demonstrators who carried banners and chanted slogans calling for the preservation of Greenland’s autonomy. Participants cited concerns over the potential loss of control of natural resources, cultural identity and internal governance should the United States gain ownership.
Organizers of the march said the event was intended to show that Greenland’s population is united across political lines in rejecting foreign pressure. Local media reported a peaceful procession that moved from the parliament building through the city center before dispersing at the waterfront. Police said no arrests were made.
European Response to Tariff Threats
Officials in Brussels, Berlin, Paris and other capitals condemned the proposed tariff measures almost immediately after the White House announcement. While each of the eight targeted countries has its own trade relationship with the United States, leaders stressed that an attempt to coerce one member of the European family will be treated as an affront to all.
Denmark’s government issued a separate statement thanking European partners for their backing and affirming that its responsibilities over Greenland’s external and security affairs remain unchanged. Copenhagen also noted that any alteration in the island’s status would require agreement from both the Danish parliament and Greenland’s lawmakers—a scenario observers say is improbable given current public sentiment.
Greenland’s Position on Autonomy
In his Monday message, Prime Minister Nielsen emphasized that Greenland’s right to self-determination is not negotiable. “The latest statements from the U.S., including threats of tariffs, do not change that line,” he wrote. “We will not be pressured.”
Although Greenland has extensive internal autonomy, its defense and diplomatic responsibilities rest with Denmark, a structure formalized in 2009 under the Self-Government Act. Any transfer of sovereignty would therefore involve both Nuuk and Copenhagen, as well as potentially broader consultations across the Kingdom of Denmark.
Strategic Importance and U.S. Interest
The U.S. government has long viewed Greenland as strategically important, in part because of its location between North America and Europe and its proximity to Arctic shipping lanes and mineral resources. Washington maintains a military presence at Thule Air Base in northwestern Greenland under an agreement with Denmark.
President Trump’s latest remarks revive a theme that first captured international headlines in 2019, when he publicly floated the idea of purchasing the island. Danish officials dismissed the proposal at the time, and Trump cancelled a planned state visit to Denmark after Copenhagen reiterated that Greenland was not for sale. The dispute cooled over subsequent years but resurfaced when the White House renewed its interest early in 2026, setting off fresh debate in Greenland and Europe.
Next Steps and Diplomatic Outlook
For now, Nielsen has placed dialogue at the center of Greenland’s strategy, welcoming supportive statements from European leaders while signaling readiness to engage constructively with Washington. Yet his remarks also make clear that any talks will occur without economic intimidation.
The White House has not responded in detail to Monday’s comments or to the weekend demonstrations in Nuuk. No timetable has been announced for the potential implementation of tariffs against the eight European countries. Trade officials in Washington have indicated that consultations are ongoing, while European trade ministers have begun internal discussions on possible countermeasures should the duties take effect.
Analysts note that the current dispute adds a layer of complexity to already sensitive transatlantic trade relations. European governments are monitoring whether the threatened tariffs materialize and how broad their scope might be. For Greenland, the episode reinforces the island’s unique position within the Kingdom of Denmark and the wider geopolitical landscape of the Arctic.
Domestic Reaction in Greenland
Local political parties across the spectrum have echoed Nielsen’s view, stating that any future dialogue with the United States must respect Greenland’s existing constitutional arrangements. Community leaders have also highlighted concerns about the potential environmental impact of expanded resource extraction should foreign ownership change regulatory oversight.
Meanwhile, civic groups in Nuuk are planning additional events to maintain public visibility of the issue. Organizers say the turnout over the weekend demonstrates widespread engagement and predicts similar participation in future gatherings if Washington proceeds with tariff measures.
While the island’s government continues to manage day-to-day domestic affairs, officials reiterate that foreign policy decisions, including any discussions over sovereignty, fall under Denmark’s jurisdiction. Copenhagen and Nuuk are expected to coordinate closely as the situation develops, presenting a unified front in official communications with the United States and European partners.
