US to build two military bases in Greenland under new deal with Denmark

The US, Denmark and Greenland have signed a defence deal that allows Washington to build two new military bases in the Arctic territory, while reaffirming Copenhagen's sovereignty over it.

Before a signing ceremony at the UN General Assembly in New York, US President Donald Trump said "we will immediately begin the process of developing a large military presence in the appropriate locations".

Danish PM Mette Frederiksen said the deal was "good for the US, Denmark and Greenland" and also for Europe and Nato, while Greenland's PM Jens-Frederik Nielsen said it was a "win-win-win".

The three leaders then inked the deal, seemingly ending more than a year of tension over the Arctic territory.

Trump had threatened to "take" the semi-autonomous Arctic territory over what he said were national security concerns, citing its strategic defence location and its mineral wealth.

His rhetoric prompted outcry from Greenlanders, Danes and European leaders who issued a joint statement saying his words "undermine transatlantic relations and risk a dangerous downward spiral".

The deal amends and updates a 1951 defence agreement between Denmark and the US.

The new pact says the US "shall be allowed to establish an additional Defence Area at Narsarsuaq and Mestersvig" - referring to locations in Greenland's south and east.

Narsarsuaq is a former civilian airport and World War Two base. It has deep-water access and a large runway which US military engineers were recently surveying, the US North Command confirmed to the BBC.

The Mestersvig outpost is remote, far less developed, and used by a Danish naval dog sled unit.

The "modalities and technical details" of the bases are yet to be confirmed, and according to the deal, must be mutually agreed by all parties,

This means the US security arrangements are not unfettered and Greenland and Denmark's approval is still needed.

Washington currently operates its Pituffik Space Base in Greenland's north-west, and the new deal allows the US to "modernise and expand its activities" there.

It also says that "no state that is not a member of Nato shall be allowed to establish its own manned or unmanned military installations in Greenland nor shall they be allowed a persistent presence of military forces in Greenland".
