The $10bn Saudi-Egyptian fund, committed to building a 1,000 sq. km mega-city in southern Sinai, was announced Monday by President Abdel-Fatteh El-Sisi and Saudi Crown Prince Mohammed bin Salman (MbS) in Cairo, where the prince launched his first public foreign trip since his appointment as heir to the throne. The Sinai city forms a segment of the prince’s plan for a new northern Saudi urban trade zone NEOM that will also take in part of Jordan. A gigantic bridge spanning the Gulf of Aqaba is planned to link the three segments of the new region, which is part of the prince’s “Vision for 2030” program. Cairo and Riyadh are in tune on a number of regional issues, including the Yemen war and the fight against the Muslim Brotherhood. The prince travels next to London and then Washington.
