China and Taiwan have lived as neighbours with the tension of an uncongenial relationship since Chiang Kai-Shek pulled his rebel forces off the mainland in 1949 after almost 30 years of struggle for supremacy. With the backing of the United States and Chiang''s iron fist, the ROC (Taiwan) claimed to represent the legitimate government of China. That status faded away in the 1970s. As the larger and more powerful entity, China has repeatedly tried to enforce a plan for reunification. This paper explores the possibility for peaceful reunification by reviewing the factors of integration theory. Additionally, China has long touted its ''one country, two systems'' concept as a workable framework for the process of integrating dissimilar systems, i.e. Taiwan and Hong Kong. This paper reviews and evaluates China’s integration with Hong Kong, from initial compatibility and problems encountered in the reintegration process to the current situation.
