WEST PALM BEACH, Fla. (AP) — President Donald Trump said Sunday that members of his newly created Board of Peace have pledged $5 billion toward rebuilding war-ravaged Gaza and will commit thousands of personnel to international stabilization and police forces for the territory.

The pledges will be formally announced when board members gather in Washington on Thursday for their first meeting, he said.

“The Board of Peace will prove to be the most consequential International Body in History, and it is my honor to serve as its Chairman,” Trump said in a social media posting announcing the pledges.

He did not detail which member nations were making the pledges for reconstruction or would contribute personnel to the stabilization force. But Indonesia’s military said Sunday that up to 8,000 of its troops are expected to be ready by the end of June for a potential deployment to Gaza as part of a humanitarian and peace mission. It’s the first firm commitment that the Republican president has received.

Rebuilding the Palestinian territory will be a daunting endeavor. The United Nations, World Bank and European Union estimate that reconstruction of the territory will cost $70 billion. Few places in the Gaza Strip were left unscathed by more than two years of Israeli bombardment.

The ceasefire deal calls for an armed international stabilization force to keep security and ensure the disarming of the militant Hamas group, a key demand of Israel. Thus far, few countries have expressed interest in taking part in the proposed force.

The Oct. 10 U.S.-brokered ceasefire deal attempted to halt a more than 2-year war between Israel and Hamas. While the heaviest fighting has subsided, Israeli forces have carried out repeated airstrikes and frequently fire on Palestinians near military-held zones.

It is not clear how many of the more than 20 members of the Board of Peace will attend the first meeting. Israeli Prime Minister Benjamin Netanyahu, who held White House talks with Trump last week, is not expected to be there.

Trump’s new board was first seen as a mechanism focused on ending the Israel-Hamas war in Gaza. But it has taken shape with his ambition for a far broader mandate of resolving global crises and appears to be the latest U.S. effort to sidestep the United Nations as Trump aims to reset the post-World War II international order.

Many of America’s top allies in Europe and elsewhere have declined to join what they suspect may be an attempt to rival the Security Council.

Trump also confirmed that Thursday’s meeting will take place at the U.S. Institute of Peace, which the State Department announced in December it was remaining the Donald J. Trump U.S. Institute of Peace.

The building is the subject of litigation brought by former employees and executives of the nonprofit think tank after the Republican administration seized the facility last year and fired almost all the institute’s staff.
