Davos, Switzerland: US President Donald Trump will unveil his new "Board of Peace" and meet Ukraine's leader at Davos on Thursday.
Trump announced on Wednesday that he was scrapping tariffs against Europe and ruling out military action to take Greenland from Denmark, partially defusing a crisis which has shaken the meeting of global elites.
On his second day at the Swiss ski resort, Trump will seek to promote the "Board of Peace", with a signing ceremony for the organisation's charter.
Trump has invited leaders including Russia's Vladimir Putin, Israel's Benjamin Netanyahu and Hungary's Viktor Orban to join.
"I think it's the greatest board ever formed," Trump said Wednesday as he met Egyptian President Abdel Fattah al-Sisi, another of the leaders who have agreed to join.
Originally meant to oversee the rebuilding of Gaza after the war between Hamas and Israel, the board's charter does not limit its role to the Strip and has sparked concerns that Trump wants it to rival the United Nations.
Key US allies including France and Britain have expressed skepticism but others have signed up, particularly in the Middle East.
About 35 world leaders have committed so far out of the 50 invitations that went out, a senior Trump administration official told reporters on Wednesday.
Trump also said on Wednesday that Putin had agreed to join -- despite the Kremlin so far saying it was still studying the invite.
Trump said he was due to hold talks with Ukrainian President Volodymyr Zelensky after the "Board of Peace" meeting as difficult negotiations for a ceasefire in the Ukraine war continue.
