The king’s office did not say where the meeting would take place, while Palestinian chief negotiator Saeb Erakat said the Palestinian Authority had “no objections” to it taking place in Jordan.
“This summit will take place on October 11 and I am to meet within the next 48 hours with Mr Dov Weissglas, Mr Sharon’s adviser, to prepare it,” he told reporters in the West Bank town of Ramallah.
But a spokesman for King Abdullah’s palace said the planned venue was not Jordan.
The encounter comes after a planned summit meeting between the pair on October 2 was cancelled following an escalation of violence in the Gaza Strip.
The Jordanian monarch telephoned Mr Abbas and Mr Sharon separately on Wednesday evening and underscored “the importance to work to guarantee a lull and put an end to the tension between the two parties”, his office said in a statement.
King Abdullah told the two leaders leaders that he still planned on
travelling to Israel and the Palestinian territories as previously announced by Jordan and that the visit would take place “when circumstances are adequate.”
He also urged Israel and the Palestinians “to pursue bilateral meetings in order to pave pave the way for a dialogue and negotiations and to build on what has been achieved after the Israeli withdrawal from Gaza.”
King Abdullah insisted that Israel and the Palestinians must remain committed to the terms of the internationally-backed Middle East “roadmap” peace blueprint.
During a visit to Washington last month, the Jordanian monarch was asked by US President George W Bush to visit Israel and the Palestinian territories and meet Mr Sharon and Mr Abbas in a bid to help re-launch the peace process.
Jordan announced on September 24 that Abdullah would visit Israel and the Palestinian territories “within days” but Deputy Prime Minister Marwan Moasher said Monday it had been delayed because of security concerns.
