Trump Wants To Buy Greenland, But The Island Is Not For Sale

President Donald Trump has reportedly asked advisers about purchasing Greenland, but the world’s largest island is not for sale.

Trump has inquired about purchasing Greenland on several occasions, according to people familiar with the discussion, the Wall Street Journal reported Thursday. Some of the inquires have been serious while others were dismissed as a joke. Greenland, a Danish territory, dismissed the idea Friday in a tweet from Greenland’s Ministry of Foreign Affairs accounts.

“We’re open for business, not for sale,” the tweet read.

Trump is not the first President to have been interested in Greenland. Former President Harry Truman reportedly offered Denmark $100 million to purchase Greenland in 1946. He also was willing to add in a portion of Alaska, CNBC reported, though offer was declined. The U.S. first explored buying the island in 1867.

Greenland is important to U.S. national-security interests, according to the WSJ. The U.S. military has almost unlimited rights in Greenland at Thule Air Base, an American base located on the island.

Trump is scheduled to visit Denmark September 2. The visit is unrelated to reports that he wants to buy Greenland, according to the WSJ.
