In an ever more globalized world, sustainable global development requires effective intercultural co-operations. This dialogue between non-western and western cultures is essential to identifying global solutions for global socio-political challenges. Modern Japanese Political Thought and International Relations critiques the formation of non-western International Relations by assessing Japanese political concepts to contemporary IR discourses since the Meji Restoration, to better understand knowledge exchanges in intercultural contexts. Each chapter focuses on a particular aspect of this dialogue, from international law and nationalism to concepts of peace and Daoism, this collection grapples with postcolonial questions of Japan's indigenous IR theory.
