Donald Trump will not be able to force Greenland to change ownership, a former top adviser to the US president has told the BBC.

IBM's vice chairman Gary Cohn, who advised Trump on the economy in his first term, said Greenland will stay Greenland and linked the need for access to critical minerals to his former boss's plans for the territory.

Cohn, also noted as a prominent figure in tech development, asserted that any assertion to invade the territory would cross a dangerous line, referring to Greenland as an independent country with NATO ties.

He hinted that Trump's recent remarks regarding Greenland may serve as a negotiating tactic rather than a genuine pursuit of change in ownership. Achieving a stronger military presence and securing an agreement on Greenland's untapped supplies of rare earth minerals, which are essential for technological advancements, seems to be a underlying goal.

The ongoing dialogue comes amidst the backdrop of the World Economic Forum, with Cohn emphasizing the growing significance of rare earth minerals and advanced technologies like AI and quantum computing in the US strategic framework.
