Aug. 8 (UPI) -- Greenland has issued a "strong warning" to an American oil company linked to President Donald Trump, as it prepares to drill on the territory despite lacking proper permits.

Local residents in the southeastern region of Jameson Land recently spotted a barge carrying drilling equipment, The Guardian reported.

The equipment belongs to Greenland Energy, a Texas-based oil company whose chairman, Larry Swets, is part of Trump's inner-circle.

Two days after a rebuke from the Greenlandic government, the president posted on Truth Social an AI-generated image showing a giant Trump, looming over the island, with the words, "Hello, Greenland!"
