In the recent period, the East Asian region has been exhibiting diverse security challenges. As the region rises comprehensively in hard and soft power configurations, it faces formidable security challenges in both traditional and non-traditional spheres. Although the region has been beset with a host of traditional security issues resulting from territoriality and sovereignty disputes between states in the region, the Non-Traditional Security (NTS) issues have started to gain increased visibility in this region. NTS threats may be defined as challenges to the survival and well-being of peoples and states that arise primarily out of non-military sources, such as threats from terrorism, climate change, cross-border environmental degradation and resource depletion, infectious diseases, natural disasters, irregular migration, food shortages, people smuggling, drug trafficking, poverty and social deprivation, and other forms of transnational crime. Increasingly, these threats have become ‘securitized’ in the minds of policy makers in many East Asian states. As such, the course aims to expose students to the analytical understanding and processes of NTS threats of East Asia. The course begins with an introduction to the key theories and methodological approaches of the discipline, before moving into an exploration of contemporary non-traditional security issues.
