In January 2026, U.S. President Donald Trump escalated tensions with Denmark and Greenland by signaling that the United States could impose tariffs on countries opposing Washington’s efforts to expand its influence over Greenland, a self-governing territory within the Kingdom of Denmark.

Trump presented Greenland as strategically important to U.S. national security, citing its location in the Arctic and its role in regional defense. He indicated that economic measures could be used to pressure governments that resist U.S. objectives, though no specific targets or legal mechanisms were identified.

The comments came as a bipartisan delegation of U.S. lawmakers traveled to Copenhagen to meet with Danish and Greenlandic leaders, aiming to ease tensions and reaffirm diplomatic cooperation. Members of the delegation emphasized respect for sovereignty and existing alliances.

Officials in Denmark and Greenland reiterated that Greenland’s political future is a matter for its people, working in partnership with Denmark. Greenland’s government has rejected any proposal involving a transfer of control, reaffirming its current constitutional status and NATO alignment.

European allies have increased security coordination in the Arctic in response to broader geopolitical pressures, underscoring growing concern over regional stability and strategic competition.

The dispute has drawn international attention due to its implications for sovereignty, alliance relationships, and the use of trade measures in foreign policy. While Trump has argued that greater U.S. involvement would enhance American security interests, Danish and Greenlandic officials have consistently maintained that Greenland is not for sale.
