However, the two sides are far apart on how specific the joint document should be, underscoring the conflicting expectations and the considerable potential for failure. The Palestinians want to take a detailed framework agreement to the conference, while Israel wants a shorter and vaguer statement.
"From now and until mid-November, the agenda should be clearly set out," Abbas said Sunday in Cairo, Egypt. "More than 36 countries will attend the conference and this big gathering requires us to go there with a definite document to pave the way later for the detailed negotiations (for) the final settlement."
Israeli officials have said the conference would at best point negotiators in the right direction, but not yield solutions to the "core" issues of any final peace settlement, such as division of the disputed city of Jerusalem and future borders.
Separately, Palestinian officials were drafting their own proposed outline of a peace deal which was being circulated among Palestinian leaders for comment. According to a copy obtained by The Associated Press, the Palestinians are ready to swap some land with Israel and limit the number of Palestinian refugees returning to their homes in the Jewish state, but also demand the return of all areas of Jerusalem captured by Israel in the 1967 Mideast war.
The draft sets several deadlines. After the signing of a framework agreement, a final peace deal should be reached within 13 months and all Israeli settlers should leave Palestinian territory within three years.
Israel is likely to object to such a timeline and the proposed division of Jerusalem.
Palestinian negotiator Saeb Erekat denied the existence of a Palestinian position paper. He also said the Palestinians will not take any documents to Wednesday's meeting between Abbas and Olmert.
Olmert's aides said he would host Abbas at his Jerusalem residence on Wednesday morning.
Initial reports had indicated the meeting would be held Tuesday, but an official in Olmert's office said it had been put back for what he said were "technical reasons."
Erekat said the two leaders would meet privately at first, and would then be joined by their teams.
Abbas and Olmert met five times in recent months, to sound each other out and build trust. Abbas said the talks were wide-ranging, "but until now we cannot say that we are negotiating."
The United States is sponsoring the peace conference, which is to take place in Annapolis, Maryland, most likely in late November. The United States wants the conference to lead to a resumption of peace talks, which broke down in January 2001. Washington wants key Arab states, notably Saudi Arabia, to attend and lend backbone to the meeting.
