# US-Denmark-Greenland Arctic security agreement > Live situation record from CLSTR: https://clstr.news/situations/us-denmark-greenland-security-agreement > Updated: 2026-09-20T01:59:31.000Z. Sources: 32. Developments: 3. The United States, Denmark, and Greenland have reached a strategic security agreement intended to stabilize the Arctic region, with a formal signing scheduled for next week on the sidelines of the UN General Assembly in New York. The deal follows months of diplomatic tension and previous threats from President Trump regarding the potential annexation of the territory. Under the terms of the arrangement, the United States will be granted permanent control over security and other essential needs in the semi-autonomous territory. President Trump stated the deal provides the US with permanent control ‘without incurring costs to the United States.’ While the agreement provides the US military with expanded access and maintains a security structure that has existed for approximately 80 years, it does not involve a transfer of land ownership to the United States. Specific provisions include permanent rights of access, basing, and overflight for the US. The agreement includes mechanisms to prevent non-NATO countries, specifically Russia and China, from establishing military bases or sending troops to the territory. Additionally, sensitive investments in the region will require US approval. The US also plans to develop a significant military presence, which could potentially include new bases in southern Greenland. Leaders from Denmark and Greenland have emphasized that the agreement respects Danish sovereignty, territorial integrity, and the right of the Greenlandic people to self-determination. French President Emmanuel Macron has endorsed the deal, stating it helps to ‘reaffirm Danish sovereignty’ and respects international law. NATO has also welcomed the agreement, noting its potential to promote security and cooperation in the Arctic. ## Claims - President Donald Trump described the pact as a mechanism that will give Washington a permanent role in Greenland's security.
