This paper is about the prospects of China’s insertion in the Middle East after the normalization agreement it has helped Iran and Saudi Arabia to reach. It explores the historical context of the agreement, analyzing first how the long-lasting rivalry developed between Saudi Arabia and Iran and then how it has expressed itself in a wide array of proxy wars that explored the internal instability and resulting civil conflicts as a way of competing for influence in the Middle East. Next, it focuses on how the People’s Republic of China has slowly established its influence in the Middle East, in what way it poses an actual challenge to the United States in the region and what means are being used by the country to ensure the expansion of its impact in the region. In the end, the paper devotes itself over the properly said agreement, studying the main motivations for each actor to engage itself in it as well its effects on regional dynamics – both noted and possible – and especially on the role played by the PRC in the Middle East.
