Saudi Deputy Crown Prince, Mohammed bin Salman, responsible for the kingdom's reforms, left on Monday for Washington to meet President Donald Trump on a visit expected to pitch the world's top oil exporter as an attractive investment destination. It will be the first meeting since Trump took office in January between the U.S. President and the prince who is next in line to lead Saudi Arabia, and is in charge of the kingdom's efforts to revive state finances by diversifying away from falling crude oil revenues, of which the upcoming Aramco IPO will be a critical component.
