Chinese leader Xi Jinping made a long-rumored trip to Saudi Arabia last week, enhancing ties between his country, the world’s top oil importer, and the leading oil exporting country. Xi and Saudi Crown Prince and Prime Minister Mohammed Bin Salman (MBS) inked a number of deals on oil, technology, infrastructure and security, and also made an agreement to avoid interference in each other’s domestic affairs. Xi also met with leaders from the Gulf Cooperation Council (GCC) and a broader group of Arab leaders. The China-Saudi summit comes amid frosty U.S.-Saudi ties and a perception among Arab leaders that Washington is pulling back from its traditional role in the Middle East, leading to some speculation of a larger geopolitical shift in the region amid the intensifying U.S-China rivalry.
