Overview
- The three parties formally signed the agreement on Tuesday, Sept. 22, 2026, at the U.N. General Assembly after months of quiet trilateral talks aimed at resolving a years‑long diplomatic rift.
- The deal allows the U.S. to modernize and expand operations at Pituffik Space Base, reopen Cold War‑era sites at Narsarsuaq and Mestersvig, and exercise wider mobility on Greenland including undersea access.
- The text bars any non‑NATO military presence in Greenland without unanimous consent by the United States, Denmark, and Greenland and highlights NATO’s role in Arctic security.
- It creates a three‑party screening mechanism requiring unanimous approval for sensitive foreign investments in sectors such as mining and infrastructure and for the first time specifies that an independent Greenland would inherit the agreement’s rights and duties.
- Greenlandic officials and residents said they felt relief that annexation fears eased but warned trust of Washington remains shaky and urged protections for hunting, fishing, environmental impact, and domestic ratification and implementation before new U.S. activity begins.
