Current events show China and the European Union working together more and more closely in energy management. The book tries to find the reasons for this and summarizes the interests behind the cooperation. Political rapport cannot exist between two great powers without “common good”; while they may not benefit equally, certainly neither suffers from their relations. It tries to present the evolution of their interaction from the beginning. The book examines this issue from the perspective of the European Union. By analyzing the history of their energy consumptions, the current energy situations and the development of their relationship, it addresses the main question: What are the reasons for the closer and closer energy dialogues between the European Union and China? Its sub-question concerns the particular motivations of the European Community for changing its energy policy and turning to China: what are the goals behind its strategy? Why has the European Union changed its energy policy so that it now regards China as one of its main partners in the energy issues? The book focuses on oil, gas and coal, fossil fuels whose value is rising as reserves diminish.
