This chapter aims at a brief description of the development on International Relations scholarship in Asia, with a special focus on Northeast Asia (China, Japan and Korea). Due to the growing role of Asia in international relations, a need to adapt and build a theoretical background for the international activities of states located there; hence IR theory in Asia has been developing especially intensely in the 21st century. In case of independent theorizing, it was built upon former developments, including (to a large extent) ancient philosophical roots. The state was an important driving force in the case not only of theory adaptation, but also development. Generally, International Relations scholarship is most developed in China, followed by Japan and South Korea. Southeast Asia, despite its traditions in certain areas, as well as South Asia, despite ancient philosophical traditions, definitely lags behind.
