Donald Trump took to the Davos stage again to launch his 'Board of Peace' on Thursday, aimed at resolving global conflicts. 

A day after declaring he wouldn't use force to acquire Greenland, the US President said: "This is a very exciting day, long in the making. Everybody wants to be a part of it. This isn't the United States, this is for the world. I think we can spread it out to other things as we succeed in Gaza.

"Once this board is completely formed, we can do pretty much whatever we want to do. And we'll do it in conjunction with the United Nations," Trump said, adding the UN had great potential that had not been fully utilized.

The mention of the UN may have been a nod towards all those expressing alarm, many of those in Europe, at the intended wider role of the 'board' originally intended to help end the Gaza war.

So what is the 'Board of Peace' and which countries have agreed to join and who has said no?

WHAT IS THE BOARD OF PEACE?

Trump first proposed the Board of Peace last September when he announced his plan to deal with the battles in Gaza. He later made clear the board's remit would be expanded beyond to tackle other conflicts worldwide.

Member states would be limited to three-year terms unless they pay $1 billion each to fund the board's activities and earn permanent membership.

With Trump as chairman, the White House has named US Secretary of State Marco Rubio, Trump's special envoy Steve Witkoff, former British prime minister Tony Blair and Trump's son-in-law Jared Kushner as members of the initiative's founding Executive Board.

WHO HAS ACCEPTED TRUMP'S INVITE?

Trump tried not to let who wasn't there hamper his unveiling party, saying 59 countries had signed on. He told a group of participating world leaders and top diplomats from Azerbaijan to Paraguay to Hungary: "You're the most powerful people in the world."

Trump said of those assembled "every one of them is a friend of mine", noting that in "most case" they were "very popular leaders. Some cases – not so popular. That's the way it goes!"

Those on the 'board' include Middle East allies Israel, Saudi Arabia, the United Arab Emirates, Bahrain, Jordan, Qatar and Egypt. NATO members Türkiye and Hungary are in, along with Morocco, Pakistan, Indonesia, Kosovo, Uzbekistan, Kazakhstan, Paraguay and Vietnam.

Others to accept are Armenia and Azerbaijan, which reached a peace agreement last August after meeting Trump at the White House.

More controversially, Belarusian President Alexander Lukashenko, long shunned by the West, has accepted Trump's invitation.

Moscow said late on Wednesday it was studying the proposal after Trump said it would join. 

The Kremlin said President Vladimir Putin plans to discuss his proposal to send $1 billion from its sovereign assets frozen in the United States to the Board of Peace and use it for humanitarian purposes. Putin noted the use of these assets would require US action to unblock them.  

WHO HAS REFUSED TO JOIN OR IS YET TO COMMIT?

The Board of Peace initiative, which comes amid a growing transatlantic rift over Greenland, tariffs and other issues, has drawn a cautious response from some close US allies who are often uncomfortable with Trump's outspoken, unilateralist "America First" approach to international diplomacy.

Norway and Sweden have declined his invitation, while Italy's Economy Minister Giancarlo Giorgetti said joining the board appeared problematic. Italian daily Il Corriere della Sera reported that joining a group led by one country's leader would violate Italy's constitution.

No other permanent member of the UN Security Council – the five nations with the most say over international law since the end of World War II – except the US has yet committed to join. As noted, Russia is considering it, but France has declined, Britain said it was not joining at present, and China has not yet said whether it will join.

Canada said it has agreed "in principle" to join but details were still being worked out. Other key US allies Germany and Japan have not yet taken a clear public stance.

Ukraine has said its diplomats are examining the invitation but President Volodymyr Zelenskyy said it is hard for him to imagine being on any board with Russia after four years of conflict.

WHAT POWER WILL THE BOARD HAVE?

The UN Security Council in November mandated the Board of Peace, but only through 2027 and to be solely focused on Gaza. Russia and China abstained, complaining the US-drafted resolution did not give the UN a clear role in Gaza's future.

The resolution welcomed the establishment of the Board of Peace as a transitional administration "that will set the framework, and coordinate funding for the redevelopment of Gaza" under Trump's peace plan until the Palestinian Authority has satisfactorily reformed.

It also authorized the Board of Peace to deploy a temporary International Stabilization Force in Gaza. The Board is required to report to the 15-member Security Council every six months on its progress.

Beyond Gaza, it remains unclear what legal authority or enforcement tools the Board of Peace will have or how it will work with the  and other international organizations.

The Board's charter says its chairman, Trump, will have extensive executive power, including the ability to veto decisions and remove members, subject to some constraints. According to its charter, the Board will undertake "peace-building functions in accordance with international law."
