Washington must establish a clear position regarding the establishment of a Palestinian state based on 1967 borders, Palestinians said after President Mahmoud Abbas and King Abdullah II concluded a meeting as part of the Jordanian monarch's visit to Ramallah on Monday.

The statement, made by Palestinian chief negotiator Saeb Erakat, came after the two leaders met in an effort to improve joint cooperation following the Temple Mount crisis that has rocked Jerusalem and provoked unrest throughout the West Bank in recent weeks.

According to Eregat, alongside full coordination on the two leaders' positions, they also agreed that Washington must clearly decide the goal for the diplomatic process between Israel and the Palestinians is the foundation of a Palestinian state on the basis of the two-state solution. He also said that Washington must agree that negotiations require a complete freeze in settlement construction, including in East Jerusalem.

The visit to Ramallah by the Jordanian leader also follows the recent shooting of two Jordanian nationals by an Israeli embassy guard after being attacked. A preliminary investigation into the incident has been opened in Israel, after Jordan made clear that the embassy would remain shuttered until an investigation take place.

According to Palestinian Foreign Minister Riyad al-Malki, the Monday meeting resulted in the construction of a joint Palestinian-Jordanian team that will be assigned to deal with future crises and seek to improve joint coordination following the latest Temple Mount flare-up.

Abbas spokesman Nabil Abu Rudeineh said that the meeting was "an important visit that constitutes a continuation of close coordination between the two sides on all levels."

According to King Abdullah, the future of the Palestinian issue is now at a crossroads and the possibility of reaching a peace agreement is becoming more difficult.

The Jordanian leader told lawmakers on Sunday that "there will be no breakthrough in the peace process if there is no commitment to supporting a solution to the Palestinian issue," Jordan's Petra news agency reported.
