This dissertation investigates the impact of the US-China trade war on regional and international cooperation patterns, with a specific focus on Iran-China relations. The ongoing rivalry between the United States and China, the world's two largest economies, extends beyond trade and into geopolitical and diplomatic realms, reshaping alliances and economic strategies across the globe. Among the countries influenced by this global shift, Iran presents a compelling case study due to its ongoing economic isolation from the West, largely driven by US sanctions. This research seeks to explore how the US-China trade war has created opportunities for Iran and China to deepen their bilateral ties and develop alternative cooperation models at both regional and international levels. The importance of this study lies in its ability to shed light on how economic conflicts between superpowers can inadvertently generate strategic opportunities for other states. By analysing the political and economic dynamics between Iran and China in the aftermath of the trade war, this research contributes to a broader understanding of shifting global power structures. The study is guided by the central research question: How has the US-China trade war created opportunities for Iran and China to strengthen regional and international relations and establish new cooperation models? Employing the Hegemonic Stability Theory, it argues that the potential decline in US dominance will catalyse the emergence of new geopolitical alignments, especially in regions where American influence has weakened. The findings reveal that the trade war has indeed acted as a catalyst for strengthened Iran-China relations. Both nations have strategically capitalised on reduced Western engagement to pursue mutual interests, enhance economic cooperation, and position themselves as key actors in a multipolar world. The study concludes that this evolving partnership exemplifies how geopolitical tensions can lead to new patterns of global cooperation, challenging established power hierarchies.
