A White House official, a surprise in the Arab countries attending the Bahrain conference "the first steps of the century," when he confirmed that Egypt, Jordan and Morocco told Washington they planned to attend the Bahrain conference to sponsor investments in the Palestinian territories.
"The participation of Egypt and Jordan is of particular importance because historically they are key players in the Israeli-Palestinian peace efforts," he told Reuters.
Palestinian President Mahmoud Abbas said the "century deal" he described as "the accord of shame" would go to hell, and that the settlement of the Palestinian issue must begin with political issues before the economy.
"The century or business issue of doom will go to hell, God willing, and the economic project in which they are working next month will also give us the illusion of hell," he said.
The Jordanian monarch also ended speculation over his country's participation in the controversial Bahrain conference, noting that Jordan should not be "out of the room" when holding international conferences related to the Palestinian cause.
That suggestion was seen as a political statement likely to involve Jordan at the Manama conference, despite the Palestinian Authority boycotting the meeting.
The plan, described by US President Donald Trump as "the century agreement", is expected to incite Arab donor countries to invest in the West Bank and Gaza Strip before tackling thorny political issues at the heart of the conflict.
In turn, called the "Palestine Liberation Organization" recently the Arab countries that announced their consent to attend the Economic Conference of Manama to reverse its decision.
The United States and Bahrain announced in a joint communique that the capital, Manama, will hold a conference "to encourage investment in the Palestinian territories," a conference that Palestinian leaders have promised to boycott on June 25 and 26.
