TEL AVIV – Palestinian Authority President Mahmoud Abbas said next month’s U.S.-led peace conference in Bahrain will “go to hell,” as will President Donald Trump’s long-anticipated peace plan.

On Sunday, the U.S. announced it would roll out the first phase of the peace proposal at the Manama forum, saying it would outline the economic rewards for the Palestinians if a peace deal were to be struck.

“The Palestinian Authority does not recognize this conference,” Abbas said.

“Trump’s ‘deal of the century’ will go to hell, as will the economic workshop in Bahrain that the Americans intend to hold and present illusions,” he added.

“Whoever is interested in proposing a solution to the Palestinian issue should begin with a diplomatic solution.”

The PA has boycotted the U.S. ever since Trump formally declared Jerusalem to be Israel’s capital in December 2017.

Last Wednesday, the PA officially rejected an invitation to the summit.

“This is an official announcement that Palestine will not attend the Manama meeting,” the PA’s top negotiator Saeb Erekat said in a statement. “This is a collective Palestinian position, from President Mahmoud Abbas and the PLO Executive Committee to all Palestinian political movements and factions, national figures, private sector and civil society.”

“Those concerned and [who] want to serve the interest of the Palestinian people should respect this collective position,” he said.

Special Mideast envoy Jason Greenblatt said the proposal has the “potential to unlock a prosperous future for the Palestinians.”

Erekat responded by saying, “Palestine’s full economic potential can only be achieved by ending the Israeli occupation, respecting international law and UN resolutions.”

Addressing the UN Security Council on Wednesday, Greenblatt said, “It would be a mistake for the Palestinians not to join us.”

“They have nothing to lose and much to gain if they do join us. But it is, of course, their choice,” said Greenblatt.

The UAE and Saudi Arabia last Tuesday announced that they would attend the Manama workshop.

Both countries are said to have pressured the PA to accept the invitation.

According to the Jerusalem Post, Saudi Arabia, Egypt and the UAE expressed “concern” over Palestinian opposition to the workshop.

“The Arabs say we should have consulted with them before publicly rejecting the workshop and calling for its boycott,” the Post quoted one Ramallah official as saying. “They are actually pressuring us to stop speaking out against the Bahrain conference and to allow businessmen to go there.”

PA Prime Minister Mohammad Shtayyeh slammed the notion of “economic peace,” said to be a cornerstone of Trump’s peace plan.

“Any solution to the conflict in Palestine must be political … and based on ending the occupation,” he said. “The current financial crisis is a result of a financial war waged against us and we will not succumb to blackmailing and extortion and will not trade our national rights for money.”

Ahmed Majdalani, the social development minister and a member of the Palestine Liberation Organization’s executive committee, reiterated Shtayyeh’s comments, saying: “There will be no Palestinian participation in the Manama workshop.”

The Palestinian leadership warned any Palestinian businessmen against taking part.

“Any Palestinian who would take part would be nothing but a collaborator for the Americans and Israel,” Majdalani said.

The only Palestinian currently set to attend the workshop is Ashraf Jabari, a Hebron businessman with ties to settlers who received a personal invitation from the Trump administration.

Greenblatt responded by saying that it is “difficult to understand why the Palestinian Authority would reject a workshop designed to discuss a vision with the potential to radically transform lives and put people on a path toward a brighter future.”

“History will judge the Palestinian Authority harshly for passing up any opportunity that could give the Palestinians something so very different, and something so very positive, compared to what they have today,” Greenblatt said.

Bahrain’s foreign minister, Khalid bin Ahmed Al-Khalifa, said last week the conference “serves no other purpose” than to help the Palestinian people “through developing their abilities and enhancing their resources.”

He reiterated his country’s support for establishing a Palestinian state with east Jerusalem as the capital.
