This course aims at equipping students with reflective and analytical ability from an international perspective via systematic understanding of how states, non-governmental organizations (NGOs), corporate or citizen engage in international organizations (IOs) to collectively solve socio-economic, ecological or sustainability problems. The course is divided into four sections, starting with discussion on why IOs were needed in the international arena and how to formulate IOs theoretically or empirically. Secondly, the operation of the United Nations will be introduced, followed by other development of IOs based on thematic discussion. Lastly, a review on future challenges of IOs in the Anthropocene will conclude the course. Through the above-mentioned course design, on the one hand students are expected to be familiar with the operation of global governance; on the other hand, the course will lead students to focus on common developmental problematics faced by nations around the world in order to expand students' future capacity to apply different professional skills and knowledge into diverse international cooperation projects.
