(File Photo)Chinese President Xi Jinping will arrive in Saudi Arabia on Wednesday for a three-day visit, his first to the world's biggest crude oil exporter since 2016, Saudi state media reported on Tuesday. The visit will include a bilateral summit chaired by Saudi King Salman and attended by Crown Prince Mohammed bin Salman, the kingdom's de facto ruler, the official Saudi Press Agency reported. China is Saudi Arabia's biggest customer for crude oil, purchasing roughly a quarter of Saudi oil exports. Xi last visited Saudi Arabia in 2016, the year before Prince Mohammed became first in line to the throne, on a trip that also featured stops in Egypt and Saudi rival Iran.
