Our project aims to investigate the triangle relations between China, Japan, and Taiwan from the end of WWII to present day. For Taiwan’s foreign relations, we evaluate from 1949 because it is part of China between 1945 and 1949 and the relevant information is discussed under China’s foreign relations. We will study each bilateral relationship separately and attempt to assess important events that may have an influence on the relations. From these events, we will outline general trends that can be seen throughout certain time periods. At the end, we will attempt to propose predictions of the future and how relations will continue to develop. Through this study, we hope to present a holistic picture of the development of relations between China, Japan and Taiwan, which could help us understand the general factors determining the foreign policy conducts of the three countries. As a result, we are able to construct appropriate policies to address the disputes that are going on recently among the three countries.
