Palestinian leaders have presented several preconditions for participating in a trilateral Israeli-Egyptian-Palestinian peace summit in Cairo, including a freeze on Israeli settlement construction, a Palestinian official told The Times of Israel.

Prime Minister Benjamin Netanyahu on Sunday reportedly told Egyptian Foreign Minister Sameh Shoukry he would be willing to meet with Palestinian Authority President Mahmoud Abbas in Cairo for talks hosted by President Abdel-Fattah el-Sissi.

The Prime Minister’s Office did not deny the report by the Saudi-owned, pan-Arab news outlet Al-Arabiya. It said in a statement that “whether the issue was discussed or not, Israel has always said it is prepared to conduct direct bilateral negotiations with no preconditions.”

The senior Palestinian official said Tuesday that Abbas had conditioned his participation on Israel agreeing to stop settlement construction and accepting a set timeline for negotiations. Israel would also have to acquiesce to negotiations based on the pre-1967 lines and pledge ahead of time to implement any agreements reached in the talks.

A senior Egyptian official told The Times of Israel on Tuesday that Egypt was seeking a formula for renewal of negotiation that would be accepted by both sides. The official said it might be too early to invite both sides to a summit, since the sides did not yet agree about the goals of the talks.

The Egyptian proposal of hosting tripartite talks may have been part of Sunday’s high-profile meetings between Netanyahu and Shoukry in Jerusalem.

Sissi reportedly offered to host direct talks between the sides as part of Cairo’s initiative to kickstart the moribund peace process.

The summit, which would also be attended by senior officials from Jordan and Egypt, would seek to engage in confidence-building measures in an effort to calm the 10-month surge in violence in the West Bank, Palestinian officials told both the London-based Al-Hayat newspaper and Israel’s Haaretz daily.

Shoukry’s visit to Israel was the first by an Egyptian foreign minister since 2007. The visit came amid speculation over the renewal of an Arab peace initiative and as Israel’s military recently saluted “unprecedented” intelligence cooperation with Egypt to combat the Islamic State group.

Speaking to journalists alongside Netanyahu before their meeting on Sunday, Shoukry said the Middle East was at a “crucial and challenging juncture.” Cairo, he added, is dedicated to “a just and comprehensive peace between the Israeli and Palestinian people.”

“The goal we aim to achieve through negotiations between the two parties is one that is based on justice, legitimate rights and mutual willingness to coexist peacefully in two neighboring independent states in peace and security,” he said.

“Egypt remains ready to assist in achieving this goal,” he said, stressing that “such a momentous achievement will have a far-reaching, dramatic and positive impact on the overall conditions in the Middle East. The current state of affairs is, unfortunately, neither stable nor sustainable.”

Shoukry, who visited Abbas in the West Bank last month, urged leaders from both sides to resume negotiations.

According to Israel’s Channel 2 television, Shoukry’s surprise visit was also aimed at arranging a first meeting between Netanyahu and Sissi in Egypt in the coming months.

The TV report said Shoukry’s first visit to Israel was coordinated between Egypt and Saudi Arabia, whose Arab Peace Initiative is backed by Sissi and much of the Arab world as the basis of any regional peace effort. Netanyahu has rejected the initiative in its current form, but said in late May that it “contains positive elements that could help revive constructive negotiations with the Palestinians.”
