WASHINGTON, Sept 18 (Reuters) – The United States, Denmark and Greenland have entered into ​an agreement that will see the ‌US develop a significant military presence on the island, while prohibiting US adversaries from building their own bases there, Donald Trump said on Friday.

In a Truth Social post, the ‌US ​president wrote that no US ⁠enemies would be ⁠able to make sensitive investments on the island without the approval of the United States and that the agreement had no expiry date.

“At my ​direction, we worked with representatives of Denmark and Greenland to guarantee that the United States ⁠will FOREVER have the complete ⁠ability to do what is necessary ​in Greenland in order to secure and defend the ​security of Greenland, and the United States ‌of America,” Trump wrote.

“Additionally, from now on, no U.S. adversary can EVER have a base in Greenland, have a military presence in Greenland, or ⁠make sensitive investments in Greenland, without our express written approval.”

Earlier on Friday, Reuters exclusively reported that the US and ⁠Greenland were ‌closing in on a deal for ⁠the island that would result in ​an ‌increased US military presence, but would ​stop well ⁠short of Trump’s long-held dream of acquiring the island for the United States.
