Israeli Prime Minister Benjamin Netanyahu has accepted an invitation to join US President Donald Trump's Board of Peace.
A statement from his office said Netanyahu would become a member of the board which is to be comprised of world leaders.
The board was originally thought to be aimed at helping end the two-year war between Israel and Hamas in Gaza and oversee reconstruction. But its proposed charter does not mention the Palestinian territory and appears to be designed to supplant functions of the UN.
The United Arab Emirates and Bahrain have also agreed to join, as have Albania, Armenia, Azerbaijan, Belarus, Hungary, Kazakhstan, Morocco, and Vietnam. Many others have expressed reservations.
It is not clear how many countries have been invited to join Trump's new body; Canada, Russia, Turkey, and the UK are among them but have not yet publicly responded. Norway has said it will not join because the current proposal raises a number of questions, while France and Sweden have indicated they will do the same.
According to a copy of the charter leaked to the media, member states will be given a renewable three-year term, but they can secure a permanent place if they contribute $1bn (£740m) of funding to the board.
The document says the Board of Peace will be an international organization that seeks to promote stability, restore dependable and lawful governance, and secure enduring peace in areas affected or threatened by conflict. It will undertake such peace-building functions in accordance with international law, it adds.
Trump will be the chairman but also separately serve as a representative of the US. A US official has said the chairmanship can be held by Trump until he resigns it, but a future US president may choose a new representative.
As chairman, he will have exclusive authority to create, modify, or dissolve subsidiary entities as necessary or appropriate to fulfill the Board of Peace's mission, according to the document.
He will also select leaders of global stature to serve two-year terms on an Executive Board that will help deliver the mission of the Board of Peace, US officials say.
On Saturday, Netanyahu's office said the Gaza Executive Board's composition was not coordinated with Israel and runs contrary to its policy.
The war was triggered by the Hamas-led attack on southern Israel on 7 October 2023, and has resulted in significant casualties on both sides. The ceasefire remains fragile, with humanitarian conditions for Palestinians in Gaza reportedly deteriorating.
