WASHINGTON, United States (AFP) — United States (US) President Donald Trump’s so-called “Board of Peace” for postwar Gaza began to take shape Saturday, with the leaders of Egypt, Turkey, Argentina and Canada asked to join.

The announcements from those leaders came after the US president named his Secretary of State Marco Rubio, former British prime minister Tony Blair, and senior negotiators Jared Kushner and Steve Witkoff to the panel.

Trump had already declared himself the chair of the body, as he promotes a controversial vision of economic development in the Palestinian territory, which lies in rubble after two-plus years of relentless Israeli bombardment.

The moves came after a Palestinian committee of technocrats meant to govern Gaza held its first meeting in Cairo which was attended by Kushner, Trump’s son-in-law who has partnered with Witkoff for months on the issue.

In Canada, a senior aide to Prime Minister Mark Carney said he intended to accept Trump’s invitation, while in Turkey, a spokesman for President Recep Tayyip Erdogan said he had been asked to become a “founding member” of the board.

Egypt’s Foreign Minister Badr Abdelatty said Cairo was “studying” a request for President Abdel Fattah al-Sisi to join.

Sharing an image of the invitation letter, Argentine President Javier Milei wrote on X that it would be “an honour” to participate in the initiative.

In a statement sent to AFP, Blair said: “I thank President Trump for his leadership in establishing the Board of Peace and am honored to be appointed to its Executive Board.”

Blair is a controversial figure in the Middle East because of his role in the 2003 invasion of Iraq. Trump himself said last year that he wanted to make sure Blair was an “acceptable choice to everybody.”

Blair spent years focused on the Israeli-Palestinian issue as representative of the “Middle East Quartet” — the United Nations, European Union, United States and Russia — after leaving Downing Street in 2007.

The White House said the Board of Peace will take on issues such as “governance capacity-building, regional relations, reconstruction, investment attraction, large-scale funding and capital mobilisation.”

The other members of the board so far are World Bank President Ajay Banga, an Indian-born American businessman; billionaire US financier Marc Rowan; and Robert Gabriel, a loyal Trump aide who serves on the US National Security Council.

Trump has created a second “Gaza executive board” that appears designed to have a more advisory role.

It was not immediately clear which world leaders were asked to be on each board.

The White House, which said Friday that additional members would be named to both entities, did not immediately reply to a request for comment.

– Israel strikes –

Washington has said the Gaza plan had gone on to a second phase — from implementing the ceasefire to disarming Hamas, whose October 2023 attack on Israel prompted the massive Israeli offensive.

On Friday, Trump named US Major General Jasper Jeffers to head the International Stabilization Force, which will be tasked with providing security in Gaza and training a new police force to succeed Hamas.

Jeffers, from special operations in US Central Command, in late 2024 was put in charge of monitoring a ceasefire between Lebanon and Israel, which has continued periodic strikes aimed at Hezbollah militants.

Gaza native and former Palestinian Authority deputy minister Ali Shaath was earlier tapped to head the governing committee.

Trump, a real estate developer, has previously mused about turning devastated Gaza into a Riviera-style area of resorts, although he has backed away from calls to forcibly displace the population.
