Even though the foregoing theories on international relations give different interpretations on this issue,they are actually interactional and overlapping.Also they seem to share more and more common features.With the acceleration of economic globalization since the end of the Cold War,nation states are increasingly interdependent in the energy sector while competition and coordination become the mainstream of international energy politics.Consequently all parties have put growing importance on international energy cooperation and its institutional construction.They believe that energy security should be achieved through international cooperation and coordination,for it is closely linked with sustainable development of economy and society as well as the external political and economic relations of nation states.
