An Analysis Of The Motives For The Adjustment Of U.S. Policy Towards China During The Trump Administration ——The Perspective Of Neoclassical Realism

Under the Trump administration in 2017,U.S.policy toward China has undergone a major shift.This policy change will have an important impact on the world pattern,but the current theoretical explanation of this issue is still insufficient.The main reason for the lack of explanatory power lies in the failure to explore the core variables that really affect the adjustment of US policy toward China.This paper adopts the perspective of neoclassical realism theory,adopts three major variables,the change of Sino-US power comparison,the threat perception of American elites,and the distribution of interests of American interest groups in China,through the cross-level analysis method.Using this theoretical perspective to analyze can explain the changes in the U.S.policy toward China since 2017,and it can also explain the changes in U.S.policy toward China in the past 50 years.This theoretical framework can not only explain the main reasons for the change of US policy towards China,but also can point out the long-term trend of US policy towards China in the future.The evolution of the U.S.policy toward China lies in the changing trend of the balance of power between the two sides,and the key to improving U.S.policy toward China lies in how to make U.S.interest groups push China-U.S.relations toward each other again and how to reduce the misunderstanding of the U.S.elites towards China.to improve its threat perception towards China.
