There is “no alternative” to a two-state solution between Israelis and the Palestinians, France told a UN conference co-chaired with Saudi Arabia on Monday.

“Only a political, two-state solution will help respond to the legitimate aspirations of Israelis and Palestinians to live in peace and security. There is no alternative,” French Foreign Minister Jean-Noel Barrot said at the start of the three-day meeting.

Days before the conference, French President Emmanuel Macron announced that he would formally recognize a State of Palestine in September.

In an interview with French weekly La Tribune Dimanche, Barrot said that other European countries will confirm “their intention to recognize the State of Palestine” during the conference, without confirming which.

“All states have a responsibility to act now,” said Palestinian prime minister Mohammad Mustafa at the start of the meeting, calling for an international force to help underwrite Palestinian statehood.
