A Study On The US-Japan-ROK Trilateral Security Interaction In The 21st Century From The Perspective Of Alliance Dilemma

After entering the new century,in order to maintain its hegemonic position,The alliance system of the United States in the Asia-Pacific has gradually developed from a "hub and spoke" system to a networked system.Due to economic and geopolitical considerations,the two traditional allies of Japan and ROK have become the targets of the United States’ efforts to win over.Since the beginning of the new century,the U.S.government has actively strengthened the two sets of bilateral alliances,and on this basis has made efforts to promote the trilateral security cooperation.Despite the twists and turns in the bilateral relations between Japan and ROK,important progress has been made in the trilateral security interaction,and the prototype of the alliance has been formed in terms of structure.However,the process of trilateral security interaction obviously shows the characteristics of vulnerability and passivity,which can not jump out of the boundary between "security" and"benefit".Since the security interaction between the United States,Japan and ROK is more likely to fall into alliance dilemma,this thesis analyzes the trilateral security interaction from the perspective of alliance dilemma theory.From the perspective of "abandonment" and"entrapment",the transition of the world system from bipolar to multipolar has diversified the choices for Japan and ROK to realize their own interests such as national security;The networking tendency of American alliance makes Japan and ROK bear more security costs;The common core interests of the three countries are not consistent and the openness of the multilateral alliance makes them deeply in the dilemma of the alliance.From the perspective of the dilemma of interest differences,Japan and ROK are highly dependent on China economically;Moreover,there are many opportunities for cooperation with China under the framework of East Asian regional integration.These factors hinder the motivation of the United States to establish a multilateral alliance in Northeast Asia.In the future,the United States will further strengthen trilateral security cooperation,making the regional situation face a great test.In the context of the long-term competition and cooperation between China and the United States,it is a high probability event for the United States to build an alliance circle surrounding China.To promote the high-quality development of trilateral security cooperation,the United States must first weaken the obstacles of the alliance dilemma.It can be predicted that the United States will disturb the regional security situation,hinder the process of regional economic integration,and divide the relationship between China,Japan and ROK.With a clear judgment on China US relations,China needs to make use of the alliance dilemma between the United States-Japan-ROK to find a breakthrough and divide the increasingly compact alliance network of the United States by various means.On the one hand,China should avoid becoming a common hostile target of the United States,Japan and South Korea,on the other hand,China should increase the cost of Japan and ROK choosing to be hostile to China,which requires China not only not to give up seeking win-win cooperation with the United States,but also to strengthen its own strength and influence.It is not only necessary to emphasize the expansion of multi-field cooperation with Japan and ROK,but also to make friends in the international community.
