Israel has been asked to join U.S. President Donald Trump’s new Board of Peace that will supervise the next phase of the Gaza peace plan, an Israeli official said Monday, while France is holding off accepting for now.

It’s not known whether Israeli Prime Minister Benjamin Netanyahu has accepted the offer, said the Israeli official who spoke on condition of anonymity because they were discussing a behind-the-scenes diplomatic matter.

Russia, Belarus, Slovenia, Thailand and the European Union’s executive arm also were among the latest to receive invitations.

It’s unclear how many leaders have been asked to join the board, and the large number of invitations being sent out, including to countries that don’t get along, has raised questions about the board’s mandate and decision-making processes. Also unknown is Israel’s potential role on a board in charge of implementing the ceasefire agreement that directly involves them.

A Trump reference in the invitation letters saying that the body would “embark on a bold new approach to resolving global conflict” suggested it could act as a rival to the U.N. Security Council, the most powerful body of the global organization created in the wake of World War II.

France, though, does not plan to join the Board of Peace “at this stage” despite receiving an invitation, a French official close to President Emmanuel Macron said Monday. The issue is raising questions, particularly with regard to respect for the principles and structure of the United Nations, said the official, speaking anonymously in line with the French presidency’s customary practices.

Morocco’s King Mohammed VI accepted a spot Monday, becoming the first Arab leader and at least the fifth world leader to join. Vietnam, Kazakhstan, Hungary and Argentina also have signed on.

Russian President Vladimir Putin received the invitation, and the Kremlin is now “studying the details” and will seek clarity of “all the nuances” in contacts with the U.S., said Kremlin spokesman Dmitry Peskov.

Belarus President Alexander Lukashenko is ready to take part, according to the country’s Foreign Ministry. The Thai Foreign Ministry said it was invited and reviewing the details.

European Commission spokesperson Olof Gill said that Ursula von der Leyen, the president of the commission, would be speaking to other EU leaders about Gaza. Gill didn’t say whether its invitation had been accepted, but that the commission wants “to contribute to a comprehensive plan to end the Gaza conflict.”

Israeli far-right Finance Minister Bezalel Smotrich on Monday dismissed the Board of Peace as a raw deal for Israel and called for its dissolution.

“It is time to explain to the president that his plan is bad for the State of Israel and to cancel it,” Smotrich said. “Gaza is ours, its future will affect our future more than anyone else’s. We will take responsibility for what happens there, impose military administration, and complete the mission.”

Smotrich, a hard-liner who opposed the Gaza ceasefire, even suggested that Israel renew a full-scale offensive on the territory to destroy Hamas if it doesn’t abide by a “short ultimatum for real disarmament and exile.”

Netanyahu said later on Monday that while there are differences with the U.S. about the composition of the advisory committee accompanying the next phase in Gaza, it would not harm his relationship with Trump.

“There will not be Turkish soldiers and Qatari soldiers in the (Gaza) Strip,” he said.

Netanyahu’s office earlier said the formation of an executive board that will work to carry out the vision of the Board of Peace wasn’t coordinated with the Israeli government and “is contrary to its policy” without clarifying its objections. Turkey, a key regional rival, is among those invited to join the committee.

The U.S. is expected to announce its official list of members in the coming days, likely during the World Economic Forum meeting in Davos, Switzerland.

Board members will oversee an executive committee that will be in charge of implementing the tough second phase of the Gaza peace plan that includes the deployment of an international security force, disarmament of Hamas and reconstruction of the war-devastated territory.

A $1 billion contribution secures permanent membership on the board, with the money going to rebuild Gaza, according to a U.S. official who spoke on condition of anonymity about the charter as he wasn’t permitted to speak publicly about details of the board, which hasn’t been made public. A three-year appointment has no contribution requirement.

According to the World Bank’s Gaza and West Bank Interim Rapid Damage and Needs Assessment (IRDNA) report released last year, it’ll take $53 billion to rebuild the strip.

British Prime Minister Keir Starmer said Monday the United Kingdom is talking to allies about the Board of Peace.

Egypt’s top diplomat on Monday met with the leader of the newly appointed committee of Palestinian technocrats who will be running Gaza’s day-to-day affairs during the second phase.

Foreign Minister Bader Abdelatty met with Ali Shaath, a Palestinian engineer and former official with the Western-backed Palestinian Authority, who was named last week as chief commissioner of the National Committee for the Administration of Gaza.

Abdelatty expressed the Egyptian government’s “complete support” of the committee and affirmed its role in running Gaza’s daily affairs until the Palestinian Authority takes over the territory, said a statement from the Egyptian ministry.
