Trump latest: Trump hails 'incredible' Davos trip - and promises Greenland 'deal' will be 'amazing' for US

That's it for our live coverage on all things Donald Trump.

Scroll down this page to catch up on developments as they happened.

Alternatively, here are the day's big headlines:

• Donald Trump, with the help of son-in-law Jared Kushner, unveiled his "master plan" for the future of Gaza on his second day at the World Economic Forum; 
• It came after US president fronted an elaborate signing ceremony to inaugurate his 'Board of Peace' initiative;

• Both big set-piece events in Davos came as the international community was still digesting Trump's dramatic U-turn on further European tariffs and Greenland;
• But NATO chief Mark Rutte told our lead world news presenter Yalda Hakim that Trump was simply trying to focus European attention on the Arctic region;
• As he jetted back across the Atlantic, Trump hailed his "incredible time" at the event and promised the proposed Greenland deal was "being worked on" and would be "amazing" for the US

• Elsewhere, Greenland's prime minster said the territory was "ready to negotiate" its partnership with the US, but that its sovereignty was a  "red line";
• EU leaders also met for an emergency summit in Brussels on the developing situation around Greenland.

There has been "no formal agreement" regarding Greenland after recent developments at Davos, the country's foreign minister has said, though she noted uncertainty remains.

In a statement after Donald Trump retreated from his threats to use tariffs as leverage to seize the Arctic island, Vivian Motzfeldt said she viewed the news from the World Economic Forum as "positive".

She said she and the Danish defence minister, Troels Lund Poulsen, met with NATO chief Mark Rutte on Monday to outline their "red lines". Greenland is a part of the Kingdom of Denmark.

She said they explained that sovereignty, territorial integrity and the Greenlandic people's self determination were not subject to negotiation.

"No formal agreement ‌has been entered into regarding Greenland... ⁠The government of Greenland ‌has not asked the secretary general ‍of NATO to negotiate on behalf of Greenland, but the secretary general has conveyed our position and red lines directly to ​President Trump," Motzfeldt said.

 "From my perspective, this is positive news from Davos."

‌Finland's President Alexander Stubb ​has said he ⁠would like a NATO plan ​for ​bolstering Arctic security ready ‍by the alliance's summit in ‌Turkey in July.

"In an ideal world, we would have ‌something ready ⁠by the NATO summit ‌in Ankara," ‍Stubb told the Reuters news agency on the sidelines of the World Economic ​Forum earlier.

Stubb said he was confident that Europe would present a united front on Greenland at the EU leaders summit in Brussels, which is now getting under way.

Donald Trump is the "leader of the free world" and if he is worried about something, "we better listen", NATO chief Mark Rutte - who has been hailed as something of a Trump whisperer - has told Paste BN.

After the US president stepped back from his threats to take over Greenland by force, Paste BN's lead world presenter Yalda Hakim unpacks what happened in Davos.

Watch her analysis of what is really going on, and see her interview with Rutte, here:

The UK is "ready to play its full part" on Arctic security, Sir Keir Starmer has said, after Donald Trump pulled back on his threats to impose tariffs or take military action to bring Greenland under US control.

The prime minister spoke to the chief of NATO, Mark Rutte, and the pair discussed "the progress made by allies on Arctic security in recent days," his spokesperson said.

"It was vital that NATO allies continued to work together to step up security cooperation in the region, they agreed," the spokesperson added.

"The UK stood ready to play its full part, the prime minister said."

Donald Trump has taken to social media as he flies back to Washington from his eventful appearance at the World Economic Forum.

"It was an incredible time in Davos," the US president said on Truth Social.

The structure of the future deal for Greenland is "being worked on" and will be "amazing" for the US, Trump said.

He added his newly inaugurated Board of Peace was "very special" and something "that the world has never seen before".

In the same month he ordered strikes on Venezuela and threatened to seize Greenland, Donald Trump has been inviting countries to join his "Board of Peace". 

The US president and disruptor-in-chief has pitched the board as a mechanism to rebuild Gaza - yet its charter does not even mention the territory. 

Russia has been invited, while still waging war on Ukraine – so what is this so-called Board of Peace? Can it achieve a lasting solution for Palestine? And is Trump trying to replace the United Nations?

Kaja Kallas, the EU's top foreign affairs diplomat, has just arrived in Brussels for the emergency summit.

She tells reporters the transatlantic relationship has "definitely taken a blow" in the last week.

Disagreements between allies like the US and EU only benefit Russia, Kallas says.

Asked about Donald Trump's Board of Peace, she adds the bloc can work with the new body if it is narrowed down to focus on Gaza.

He has boarded Air Force One in Zurich, leaving the World Economic Forum digesting the impact of Trump 2.0.

Donald Trump's participation there has demonstrated two things - the extent to which the world gravitates towards and around him; and the extent to which he thrives on validation. 

From Greenland to Gaza to Ukraine, everything revolved around the 79-year-old president of the United States.

NATO boss Mark Rutte gave a masterclass in the art of approval, massaging the ego of the world’s most powerful man. Many will criticise him for that, but it produced the desired result - a "deal" on Greenland that appears to do little but reaffirm the status quo. 

But it has taken threats to seize Greenland by force or declare a US/European trade war off the table, for now.

Nineteen world leaders queued up for a picture with the president as they signed up to his Board of Peace for Gaza – more validation.

And Volodymyr Zelenskyy adopted the same tactic, comparing Europe's approach to Greenland with Trump's approach to Venezuela.

The Ukrainian leader thanked Europe for security guarantees but added: "The backstop of President Trump is needed." There is it again – validation.

His "top-billing" speech lacked energy and he clearly mistook Iceland for Greenland several times, but Trump achieved what he went to do.

He has reminded the world that the US is the dominant player on the stage and that he is the disrupter-in-chief.

We've just been hearing from Europe correspondent Alistair Bunkall in Brussels as European leaders arrive for their summit.

"The last 24 hours in Davos have changed things," he says.

"It's taken the heat out of things here tonight. I don't think it's necessarily taking the significance out of tonight.

"The mood has changed in Europe, it really has. 

"There is a feeling that European leaders need to be united and they need to just take a tougher stance, generally, with the US president. 

"And of course, they really do realise that they need to be more self-reliant."
