US media report that Trump has instructed aides to look into the possibility of the US to purchasing the autonomous Danish territory, as well as its potential resources and geopolitical benefits.

Trump told reporters on Sunday that the prospect is strategically attractive, and his administration would be interested.

He said he will talk with the Danish government, although it's not on the top of his agenda.

The president is expected to visit Denmark next month.

Trump has also said purchasing Greenland would be a major real estate deal.

US media have been critical of the idea, saying Trump appears to be mixing the real estate business with diplomacy. The president is believed to have made a fortune as a developer.

The Danish government has dismissed the idea, saying Greenland is not for sale.
