Chapter two discusses the complexities of American foreign policy in the South China Sea, focusing on the tensions arising from China's territorial claims and military expansion. The U.S. response has evolved, with notable events including military patrols and increased naval presence aimed at countering China's actions, while geopolitical interests surrounding shipping routes and energy reserves influence policy decisions. The chapter also outlines theoretical perspectives, such as realism, neoliberalism, and constructivism, which provide insights into understanding international relations and the interplay of power in defining foreign policy.
