Washington ? Arab holdout Syria agreed Sunday to attend a Mideast peace conference called by President Bush to restart talks to resolve the six-decade conflict between Israel and the Palestinians, yet expectations for the summit remained low. The two sides came to Washington without agreeing on basic terms for their negotiations.

Bush invited the Israeli and Palestinian leaders to separate meetings at the White House today to prepare for the centerpiece of his Mideast gathering – an all-day session Tuesday in Annapolis, Md. It is to be the only time that Bush, Israeli Prime Minister Ehud Olmert and Palestinian President Mahmoud Abbas meet together, and their three-way handshake is expected to be the conference’s symbolic high point. Bush closes the U.S. effort with a second set of separate Israeli and Palestinian meetings at the White House on Wednesday.

“The broad attendance at this conference by regional states and other key international participants demonstrates the international resolve to seize this important opportunity to advance freedom and peace in the Middle East,” Bush said in a statement Sunday.

Israeli and Palestinian negotiators were meeting with Secretary of State Condoleezza Rice and her deputy for the Mideast region, still trying to write a framework for talks that their U.S. hosts had hoped would be complete by now. Rice’s spokesman said the last-minute work is not surprising.

“We’re confident there will be a document and we’ll get to Annapolis in good shape on that,” but bargaining may well continue behind the scenes during the session Tuesday, State Department spokesman Sean McCormack said in an interview.

“It will memorialize their common understandings to this point,” and look ahead to negotiations the two sides expect to begin in earnest after the session, McCormack told The Associated Press.

Separately, Palestinian negotiators Ahmed Qureia and Saeb Erekat met with Tzipi Livni, Israel’s lead negotiator, for unscheduled talks Sunday. Asked if they were optimistic about the prospect for reaching a consensus on a joint declaration, Qureia replied, “You don’t meet if you’re not optimistic.”

Assistant Secretary of State for Near Eastern Affairs David Welch also met with Palestinian negotiators Sunday in an attempt to reach a breakthrough, a member of the Palestinian delegation said.

Bush’s national security adviser, Stephen Hadley, said the joint statement was not as important as it might have seemed when it was first broached. The two sides took the unexpected step of seeking negotiations, and the declaration no longer needed to serve as a vehicle to prod them to do so, Hadley said.

“If we get something, if they can agree on some things as an input to the negotiations, that would be fine,” Hadley said. “But I think it is really no longer on the critical path to a successful conference.”

The Bush administration, which has largely taken a hands-off approach to the nitty-gritty of Mideast peacemaking until now, says the goal is to set up an independent Palestinian state alongside Israel. Israeli and Palestinian leaders have said they want to do that by the time Bush leaves office in January 2009. While there are widespread doubts in the administration about that time line, Rice has said she is game to try.

“This is not a negotiation session, it is to launch negotiations,” Hadley said.

Hadley said that during his address to the conference Tuesday, Bush will make clear that the Mideast peace process has his support, and that it is a top priority for the rest of his time in office. But he is not expected to use his speech to advance any of his own ideas on how to achieve that by wading into the issues that have kept the parties bitterly divided.

The conference is meant to draw Arab and other outside backing for what will be difficult negotiations. The idea is also to let Arab states have their say alongside Bush, making it more difficult for them to complain that Washington is not doing enough or is not listening to good advice from those closest to the conflict.

Syria, which borders Israel and has no diplomatic relations with the Jewish state, gave Washington a partial victory Sunday by agreeing to send a lower-level envoy to the session. Syria wants to raise the question of the Golan Heights, strategic territory Israel seized from Syria in the 1967 war. The U.S. hosts and Israel have agreed, at least tacitly, to listen.

Other major Arab states whose participation was considered essential decided Friday to send their top diplomats.
