The United Nations raised the idea of a meeting bringing together Israel, the Palestinians and Arab states to try to revive peace talks as U.S. Secretary of State Condoleezza Rice on Monday shuttled between the sides.
The intensified diplomacy comes ahead of an Arab summit expected to relaunch a Saudi-backed peace plan calling for Israel to quit all occupied Arab lands in exchange for peace.
Israeli Prime Minister Ehud Olmert said he would "not hesitate to participate" if invited to an expanded meeting of the Quartet of Middle East mediators that could also include Saudi Arabia.
U.S. officials played down the idea, saying it was one of several possibilities under consideration and that no decisions had been made.
A public meeting that brings Israeli and Saudi leaders together would be a breakthrough. The countries do not have formal relations, though there have been reports of informal Saudi contacts with Olmert.
During a brief visit to Amman, Rice met for a second time in 24 hours with Palestinian President Mahmoud Abbas, as well as with Jordan‘s King Abdullah. She will return later to Jerusalem for further talks with Olmert.
Rice met separately on Sunday with Abbas and Olmert to gauge the chances for peace talks but said she was not striving for a "big bang" breakthrough.
On her fourth visit to the Middle East in four months, Rice is talking to the Israelis and Palestinians separately because Olmert has so far ruled out engaging Abbas on peace since the Fatah leader formed a unity government with the Islamist Hamas.
Rice has been encouraging Arabs to revive the peace plan they ratified in 2002 by adding what she calls "active diplomacy" -- seen as code for early contacts with Israelis.
But Jordan said that Arab foreign ministers agreed on Monday that this week‘s Arab summit would revive an Arab initiative for peace with Israel without any amendments.
U.N. Secretary-General Ban Ki-moon, also on a visit to the region, said on Monday that Israeli and Palestinian leaders, along with officials from Saudi Arabia, Egypt, Jordan and the United Arab Emirates, could be invited to attend the next Quartet meeting, expected to take place in Egypt.
"It is a very interesting, useful idea to consider. But we need more consultations," Ban said.
STICKING TO ROAD MAP
The United Nations is part of the Quartet, whose other members are the United States, the European Union and Russia.
At a press conference in Jerusalem with Ban, Olmert said he would continue his contacts with Abbas and that a long-stalled "road map" peace plan "will be the basis for advancement here between us and the Palestinians."
Neither the Israelis nor the Palestinians have fulfilled their commitments under the road map, which calls for Israel to halt settlement building in the occupied West Bank and the Palestinians to dismantle militant groups.
The 2002 plan touted by Rice, known as the Saudi initiative, offers Israel normal ties with Arab countries in return for full withdrawal from land it occupied in the 1967 Middle East war.
Olmert urged Arab states to advance the proposal but Israel has said it cannot accept some of the terms.
Israel and the Quartet have demanded the Palestinian government recognize Israel, renounce violence and accept existing peace deals.
The new unity administration has agreed only to "respect" previous accords and has stopped short of recognizing Israel or giving up the right to armed struggle.
Analysts doubt Rice can make much progress given Olmert‘s political weakness -- one opinion poll this month showed he would win as little as 3 percent of the vote if an election were held immediately -- and the divisions among the Palestinians.
