In recent years, much research has been devoted to the analysis of the US-China relationship. However, few have deployed the content analysis of the joint statements between both countries in order to grasp the change of the relationship in different time frames. In fact, grasping the trend change of the US-China relationship is imperative for academic researchers and policy makers. In this paper, we analyzed the trend change of the US-China relationship by means of applying the text mining analysis to two joint statements in the years of 2009 and 2011. The contribution of this study included the following two points. First, the study has found the main focus of the Joint Statements shifted from mutual cooperation to the focuses of economic development, investment and the continuity of bilateral relations. Second, the study found a new way of literature survey in diplomatic studies by using the text mining method in order to explore the trend change.
