Israel's 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. However, 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 well as 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 several 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 $1 billion (£740 million) of funding to the board.
The document states that 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.
Trump will serve as the chairman but also separately serve as the representative of the US. A US official has confirmed that the chairmanship can be held by Trump until he resigns it, but a future US president might 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.
Last Friday, the White House announced the seven members of the founding Executive Board, which included US Secretary of State Marco Rubio, Middle East special envoy Steve Witkoff, Trump's son-in-law Jared Kushner, and former British prime minister Tony Blair.
Trump also named Nickolay Mladenov, a Bulgarian politician and former UN Middle East envoy, as the Board of Peace's representative on the ground in Gaza during phase two of Trump's peace plan, which aims for the reconstruction and demilitarization of the territory, including the disarmament of Hamas and a full withdrawal of Israeli forces.
Mladenov will act as a liaison with a Palestinian technocratic government tasked with overseeing the restoration of core public services and stabilizing daily life.
On Saturday, Netanyahu's office said the composition of the Gaza Executive Board was not coordinated with Israel and runs contrary to its policy.
Under phase one of the peace plan, Hamas and Israel agreed to a ceasefire, share of living and dead Israeli hostages in Gaza for Palestinian prisoners in Israeli jails, partial Israeli withdrawal, and a surge in humanitarian aid deliveries.
Despite the ceasefire, conditions in Gaza remain dire, with humanitarian efforts ongoing amidst ongoing hostilities, as over 71,550 people have been killed in the territory as reported by health authorities.
