The Palestinian Liberation Organization (PLO) outlined three conditions for Israelis to meet before resuming peace talks.
The new conditions came as the United States prepares to hold a series of separate talks between the Palestinian National Authority (PNA) and Israel in Washington to push the two sides forward to resume direct negotiations.
Ahmed Majdalani, a member of PLO executive committee, said one of the conditions is that "a reference for the negotiations must be allocated."
He told Xinhua that the peace process "must stand on the international resolutions that call for establishing an independent Palestinian statehood under the two-state solution."
Majdalani said the PLO demands a timetable for the negotiations as the second condition. "We don't want to engage in negotiations just for talking; we need a time ceiling leading to the statehood."
The peace talks have been stalled for months and Palestinian President Mahmoud Abbas insisted they would not restart peace talks unless Israel stops Jewish settlement in the West Bank.
Majdalani said a complete halt of settlement activities is the third condition the PLO put.
"Without these basis, we, the Palestinians, don't want to continue useless negotiations, given the right-wing Israeli government's stances that undervalues the peace process and defies the international consensus," Majdalani said.
The PLO's conditions were meant to underline that Abbas has not dropped his demand for Israel to stop the settlement activities.
A meeting between Abbas, U.S. President Barack Obama and Israeli Prime Minister Benjamin Netanyahu last week paved the way for the upcoming talks in Washington.
George Mitchell, the U.S. Middle East envoy, is expected to lead the discussions with the Israeli and the Palestinian negotiators next month.
The three-way summit, which was held on the sidelines of the UN General Assembly in New York, was the first face-to-face meeting between Abbas and Netanyahu since the latter took office in early April.
Established in 1964, the PLO, an umbrella organization made up of a handful of organizations, is recognized as "the sole legitimate representative of the Palestinian people."
