The Quadrilateral Security Dialogue, also known as the Quad, is a strategic forum comprising Australia, India, Japan, and the United States. It aims to promote regional security and cooperation in the Indo-Pacific region and sets climate action as one of its priorities. China, as the world’s largest emitter of greenhouse gases, has become a key player in global climate governance. The potential for climate cooperation between the Quad and China is thus of great significance in addressing the climate crisis. This thesis aims to analyze the potential for minilateral climate cooperation between the Quad and China from the perspective of neoliberal institutionalism. It first discusses previous climate cooperation between China and the Quad countries, examining the significance of collaborations for the potential ‘Quad Plus China’ climate cooperation. Then, it analyzes the current attitudes and policies of China and the Quad to explore their willingness to cooperate. Finally, it finds that the cooperation is feasible in several fields based on a neoliberal institutionalist framework and elaborates on the impact of doing so for China, the Quad countries, and the rest of the world.
