The ultimate ambition of the project is to explore whether EU can be the new international new regime maker by initiating the liberalism through its effort to negotiate, contract as well as sustainably adjust the agreements with third countries based on the externalization of Normative Power Europe. Or China will play a more important role in international regime making by using its Regional Multilateralism, Normative Power China, under the One Belt One Road Grand National Strategy to deal with EU’s liberalism. Can EU’s liberalism or China’s regional multilateralism be winning the battle of regime making?

The research will be done through case studies within the context of the Japan as the potential kingmaker. Due to the fact that without the Japan’s engagement, the international regime in the Asia Pacific region cannot be regarded as real international.

Game Theory analysis will be used as the method to explore whether EU or China can make a new model of international regimes as new regime maker in the world. The four game theory scenarios between China and EU’s rational interactions will be exposed, while the four payoffs of China and EU’s each within four different contexts of EU and China’s rational behavior patterns will be compared vertically and horizontally. More importantly the flows between four game theory interaction scenarios will be analyzed to figure out the pros and cons in line with the gains and losses during the flows to identify the most stable scenario for the two parties to have the agreements signed, through which building the new international regime can be regarded as the fruit produced by the interplays between EU’s liberalism and China’s regional multilateralism initiated by the One Belt One Road National Grand Strategy of China.

The research findings from Krasner, Ikenberry, Keohane, Nye, Stein, Powell and others in relation to regime theory as well as game theory will be reviewed, and exploratory study of my research approached by Game Theory analysis can contribute a new dimension to both academic discussions as well as practical operations of international politics. The research finds out that EU and China all have potentials of being the new international hegemon with the ideology of liberalism or regional multilateralism.
