With a comprehensive 25-year partnership with Iran and a comprehensive strategic partnership with Saudi Arabia, Beijing is shifting its non-interference strategy to a constructive intervention. Despite much research on China’s role in its relationship with Iran and Saudi, little attention has been on Beijing’s national role conceptions. The purpose of this research is to analyze China’s position and role performance in accordance with China’s national role conceptions from a role theory perspective. The methodology adopts a descriptive method with qualitative analysis. The research strategy is qualitative content analysis. Governments’ official websites, leaders’ speeches, and meetings are analyzed to provide China’s national role conceptions in Beijing’s role performance and position. The analysis concludes that China has a different position from Tehran and Riyadh according to each country’s status and circumstances. The thesis findings contribute to the wider academic research that tries to explain how PRC’s national role conceptions affect the role performance and position of Beijing in its relations between Tehran and Riyadh.
