Sino-US strategic rivalry and regional security dynamics in the South China Sea

The South China Sea is a crucial region that has become a focal point of territorial disputes and geopolitical tensions between China and its neighbouring countries, resulting in complex security dynamics. Against this backdrop, the US has sought to counter China's assertiveness in the region, resulting in a strategic rivalry that has far-reaching implications for regional security. The study's theoretical framework is based on Neo-realism, which posits that state behaviour in the international system is driven by self-interest and the desire for power and security. The concepts of offensive realism and balance of power play a supportive role in the research. The researcher adopted a qualitative method to carry out this study. Drawing on existing literature and analysis, this study explores the emerging China-US rivalry and key drivers behind their rivalry in the South China Sea, including economic and military factors, as well as broader geopolitical considerations. China has concentrated on developing its military capabilities and increasing its influence in the region through diplomatic, military, and economic means. Furthermore, this strategic rivalry affected the regional security dynamics that led to the militarisation of the SCS, an arms race, alliances, instability, and heightened regional tensions.
