U.S. President Donald Trump promised not to build skyscrapers with his engraved surname in Greenland, a day after he confirmed that he was considering buying a sparsely populated Arctic island.

The photo published by the President of the US depicts a golden skyscraper with the inscription "Trump", placed with photoshop.

“I promise not to do this to Greenland!” Trump tweeted.

On Sunday, Trump confirmed the rumors that his administration is considering buying Greenland, which is a semi-autonomous territory controlled by Denmark.

Danish PM Mette Frederiksen said his idea is absurd.
