With the evolution of the times, the UN's definitions of security have been changing. During the Cold War period, the UN's
concept of security was interpreted narrowly to mean territorial security from external aggression, security to maintain national independence, or security from global nuclear war. At the same time, a new security concept emerged gradually within the UN, identifying security in a more comprehensive way. Since the end of the Cold War, the UN has been advocating a new security concept and related notions, including“human security,” “common security,”and“global security.”This has led to the
transformation from a
traditional to a non-traditional UN security concept. As a result of the balancing of different national and regional security needs, the new UN security concept is characterized by more idealism, institutionalism, and globalism. On the one hand, we should recognize that the transformation of the UN security concept is a reflection of the changing world environment and of the shifts in national security interests, so it should have positive and instructional bearings on the UN member states. But, on the other hand, we should be mindful of the new problems caused by too broad of a definition of security and by abuses of“non-traditional security.”
