"We are still waiting a chance to be given to movement Egypt has exerted basically to resume the negotiations with the Israeli side," Azzam al-Ahmad, a leader of President Mahmoud Abbas's Fatah party, told Voice of Palestine radio.
He added that Egypt was preparing a plan to revive the talks, stalled since Israel launched a war on the Gaza Strip a year ago.
Over the past two weeks, Palestinian and Israeli leaders held separate meetings in Cairo with Egyptian President Hosni Mubarak in a bid to bridge the gaps preventing the resumption of the peace negotiations.
Al-Ahmad said that Egyptian Foreign Minister Ahmed Abul Gheit and intelligence chief Omar Suleiman will visit Washington "to push the United States to present clear stances and steps completely meeting the peace process and its requirements."
He also said that the Israeli media reports about an imminent U.S. plan foreseeing a Palestinian state in 2012 were "inaccurate."
The construction of Jewish settlements in the West Bank and East Jerusalem has undermined the efforts to resume the talks, since the two territories would be part of the future Palestinian state with East Jerusalem as its capital.
