Frédéric Krumbein presents a five-theory framework designed for analyzing the complex relationship between Taiwan and China. The article offers a toolkit for understanding the factors shaping cross-strait relations, moving beyond simplistic interpretations. These factors include historical decisions that have influenced current dynamics and the increasing economic integration between Taiwan and China. The framework also considers shifting identities on both sides of the Taiwan Strait, and the crucial element of regional security. By evaluating these interconnected elements, Krumbein aims to provide a method for predicting potential future developments in Taiwan-China relations, regardless of the level of political focus. The analysis allows for mapping potential trajectories based on varying political conditions and priorities.
