ANKARA — Custodian of the Two Holy Mosques King Salman on Monday arrived in Turkey wrapping up a landmark five-day visit to Egypt marked by multi-billion-dollar investment deals. The King will attend the 13th annual summit of the Organization of Islamic Cooperation (OIC) scheduled for Thursday-Friday. The annual OIC conference began with senior officials adopting the agenda and will be followed by a foreign ministers meeting on Tuesday and Wednesday. Over 30 heads of state and government will attend the summit hosted by President Recep Tayyip Erdogan on Thursday and Friday. On Monday, Cairo University conferred on the King an honorary doctorate for his services to Arabs and Muslims. In its citation, Cairo University said King Salman was a "global and pivotal figure with massive influence in the Arab and International arenas" and praised his support for Egypt and the university. Over the past five days, King Salman and President Abdel Fattah El-Sisi oversaw the signing of a slew of multi-billion-dollar investment deals that included a plan to build a bridge over the Red Sea connecting Saudi Arabia and Egypt. Egypt also agreed to demarcate its maritime borders with Saudi Arabia by officially placing two islands in the Straits of Tiran in Saudi territory.
