The Palestinians expect Kerry to propose cosmetic steps without providing final answers on a return to negotiations, the official said.
Senior PLO official Mohammad Shtayyeh said Tuesday that the Palestinians appreciated Kerry's efforts, but that Israeli policies were impeding them.
Continuous settlement building and the Israeli government's refusal to recognize a Palestinian state on 1967 borders demonstrate that Israeli Prime Minister Benjamin Netanyahu does not intend to reach a two-state solution, Shtayyeh told reporters after a meeting with Carter Centre director
"We have told Kerry that we will return to the negotiating table if Israel proves its seriousness by agreeing to stop building in settlements and by releasing prisoners," Shtayyeh said.
"We are waiting for the results of Kerry's efforts and if they fail, our next destination will be the organizations of the United Nations," he added.
Abbas is pushing Israel to freeze all settlement building activity and to publicly agree to make the lines that existed before the 1967 Middle East war the basis for peace negotiations.
