The main purpose of this article is to examine the possibilities of framing multilateral energy security institution in Northeast Asia. The purpose of this article is neither to discuss KEDO nor to deal with North Korea’s nuclear proliferation issue, nor to focus on EU energy policy but to elaborate original idea and concept of both KEDO’s and EU’s limited achievements and to apply them to the potential building regional energy security framework in Northeast Asia. The article contends that both KEDO and ECT approaches toward energy security are equally quite helpful to the case of Northeast Asia because they promoted active role of government participation and intervention, although both cases are somehow incomplete and different each other. Moreover, the paper argues that as the natural gas age is approaching, natural gas trade among Asia Pacific states increases, the establishment of multilateral energy security in the region is must be done task in the region, in order to mitigate potentially both man made and natural energy crisis among states.
