States within the international system are rarely self-contained units and are repeatedly confronted with situations that easily transgress their managing capabilities. In order to cope with these situations, states tend to cooperate with other actors through institutions. Common examples include the creation of institutions like the EU, the WTO, or even contractual frameworks like the Paris Climate Agreement. An important role have regionalized forms of cooperation that are usually defined by shared geographic, cultural, or historic characteristics and eventually lead to various forms of integration. This seminar focuses on regionalized integration processes and institutions in the South China Sea Region. Here, we will discuss the different forms of integration processes, actors, and sources of conflict. Main emphasis will be placed on the Association of South East Asian Nations (ASEAN) as main regional organization, China as important regional power and current issue areas like the Chinese Belt and Road initiative and the conflict in the South China Sea.
