To provide a sufficient analysis structure, scholars apply various international relation theories or models to describe, explain and predict the evolution of the cross-strait relation. The ”strategic triangle” approach is not only strict in logic structure but also covers the interaction among the three main actors namely Mainland China, Taiwan and the United States. The approach, supplemented by the real-term relation among the three player in the Clinton period, is used in my paper to demonstrate that, without considering internal factors, their relation will move in the direction of amicability rather than conflict.
