The prime minister of Greenland, which is coveted by US president Donald Trump, said Monday he was seeking ‘concrete results’ from on-going talks with Washington.

Prime minister Jens-Frederik Nielsen’s comments came as the Danish autonomous territory’s parliament opened its latest session.

‘The dialogue has begun, and the Naalakkersuisut (the Greenlandic government) will work with determination to bring it to concrete results,’ Nielsen told the Inatsisartut, or the parliament.

Trilateral talks began after Trump in January backed down from his threats to seize the autonomous Arctic territory of EU and NATO member Denmark.

The first meeting of the working group was held on January 28 in Washington, bringing together senior Danish, Greenlandic and US civil servants.

‘It went well in a very constructive atmosphere and tone, and new meetings are planned. It’s not that things are solved, but it’s good,’ Danish foreign minister Lars Lokke Rasmussen told reporters the next day.

‘I’m slightly more optimistic today than a week ago,’ he added.

Nielsen, who together with Denmark’s prime minister met with French and German leaders last week, said talks with the Trump administration must take place in parallel with the strengthening of ‘close dialogue with Western countries’ and cooperation with the European Union.

‘We are not alone, and we are protected. All EU countries support us,’ he stressed.

He also reiterated that ‘Greenland can neither be bought nor sold’.

Trump’s threats over Greenland plunged the transatlantic alliance into its deepest crisis in years.

The US leader backed off his desire to seize the island after saying he had struck a ‘framework’ deal with NATO chief Mark Rutte to ensure greater influence from Washington.

But few concrete details appear to have been agreed, with authorities in Denmark and Greenland refusing to discuss handing over any sovereignty.
