President Donald Trump has announced that the United States has reached a new security agreement with Denmark and Greenland that he says gives Washington “permanent control over security” and other security-related needs in Greenland.

“I am pleased to announce that the United States of America has entered into an Agreement with The Kingdom of Denmark, and Greenland, that gives the United States permanent control over security, and all other needs, in Greenland, completely addressing ALL of our many U.S. concerns,” Trump said in a post on Truth Social.

Trump said the agreement would come at “NO COST” to the United States and described it as an “‘Infinite Life’ Agreement” with no end.

Under the arrangement, Trump said U.S. adversaries would be barred from establishing military bases or maintaining a military presence in Greenland, as well as making sensitive investments, without written approval from the United States.

The agreement is also expected to strengthen U.S. access to Greenland and expand the American military presence there.

Trump said his administration would work with Greenland to begin developing a “large Military presence” in appropriate areas of the island.

U.S. officials have said the agreement would prevent countries such as Russia and China from establishing military bases or deploying troops in Greenland, while also creating mechanisms to restrict investments in sensitive sectors that could pose security concerns.

Secretary of State Marco Rubio said the agreement would keep Greenland within the strategic defense area of North America and address U.S. national-security concerns.

However, Danish and Greenlandic officials have emphasized that the agreement recognizes the sovereignty and territorial integrity of the Kingdom of Denmark, as well as the Greenlandic people's right to self-determination.

The pact is expected to be formally signed next week and remains subject to parliamentary approval in Denmark and Greenland.

The announcement marks a significant development in the long-running dispute over Greenland, which Trump has previously sought to bring under U.S. control.

The island remains an autonomous territory within the Kingdom of Denmark.
