In a post on his Truth Social platform on Wednesday, Trump said that the Arctic island holds some of the world's largest reserves of 'easily' extractable oil.
'Massive Oil, Gas, and Mineral Exploration is getting ready to begin in our new and beautiful Greenland!' Trump wrote. 'The amount of easily available Oil is far greater than that of almost … anywhere in the World.'
The post did not provide details of potential US involvement or a timeline for the start of exploration.
The announcement follows a security deal reached last month between the US, Denmark and Greenland. That agreement expands the US military presence on the island, paving the way for two new bases and the planned 'Golden Dome' missile defence system, while reaffirming Danish sovereignty and Greenlanders' right to self-determination. The pact was aimed at ending a prolonged crisis over Trump's refusal to rule out seizing Greenland by force.
Trump also highlighted the defence advantages of the arrangement, stating that any future aerial attack against the United States would have to cross Greenland, giving Washington 'time, location, and sightline, like nowhere else in the world.'
As of Wednesday, there was no immediate comment from the leaders of Greenland or Denmark.
