왜 비국가 행위자를 말하는가?

In the Westphalian system States had been at center of international legal system and the international law had been only concerned with the rights and duties of States until mid-20th century. Wide proliferation of activities of non-State actors in the international arena in recent years makes us to rethink the exclusive role of States in the traditional areas of international law. This article, as a kind of prologue at the seminar on“Non-State Actors in International Law” organized by the Seoul International Law Academy, raises some basic questions: Who are non-State actors?, Why do we need to talk about them?, What is legal implication of the activities of non-State actors in international forum?, How do we have to translate non-State actors into Korean? This article does not necessarily try to provide clear answers to these questions, but asks more debate among academic circle about this topic.
