Denmark's Prime Minister insisted yesterday that Greenland's future should be decided by its inhabitants, amid talk of Washington annexing the Danish autonomous territory.

"Greenland belongs to the Greenlanders," Prime Minister Mette Frederiksen said, adding that the Arctic territory "is not for sale" as Donald Trump Jr, son of US President-elect Donald Trump, visited Greenland weeks after his father suggested the US take control of the island.

This is not the first time Trump has shown an interest in Greenland, where the US already has a military base.

He said he wanted to buy it in 2019, during his first term as president, an offer quashed by Greenland and Denmark.
