After experiencing World War ¢¹and ¢º, the European countries recognized that to prevent war on Europe was of necessary. They would like to inspire economic development by economic integration, and furthermore, to push Europe back to the key actor of world politics through political integration. From ¡§European Common Market¡¨, ¡§European Community¡¨ to ¡§European Union¡¨, the European countries has gone through many complex negotiations. Among the regimes in European Union, ¡§Common Foreign and Security Policy¡¨ works through ¡§Intergovernmental Cooperation¡¨, which is of much higher political meaning. It symbolizes the operation of integration theory has strode from economic to political matters. The operations of CFSP have two important contributions to Europe. First of all, it contributed to the reconciliation of European nations. Second, it demonstrates peace can be achieved through legal and institutional negations without threatening the existing political authorities. Both China and Taiwan can take lessons in the CFSP¡¦s negotiation process, especially in the aspects of how to leave aside disputes and put aside minor differences so as to seek common ground. President Chen Shui-Bian gave a talk on 31 December 2000 which indicated that the Cross-strait relation could learn from EU¡¦s integration experience and jointly seek for new framework of political integration. It could start from economic and cultural integration, build confidence step by step, and look for new framework for political integration. This kind of opinion conforms to international development experience. What norms of EU¡¦s experience should the Cross-strait refer to is the main topic of this research. How do EU¡¦s institutions make compromise between ¡§national interest¡¨ and ¡§EU¡¦s development¡¨ is another concerning point of the research.
