| With the adjustment of the international situation and the shift in the balance of power between China and the United States,the United States has misjudged China’s development,and the anti-China sentiment in the United States has become stronger and stronger.The negative factors in Sino-US relations have become increasingly prominent.The Trump administration overthrew the diplomatic legacy of the Obama administration,re-adjusted the U.S.global strategy,and at the same time re-examined and reflected on its China policy.The increasing political polarization of the United States attempts to transfer domestic contradictions by adopting tough measures against China.It no longer continues the previous single strategy of “containment” and “engagement” to formulate a policy toward China,but it opens a new stage in the development of Sino-US relations with the positioning of strategic competition.This article takes the Trump administration’s “strategic competition” with China as the starting point,and compares and combs the US policies towards China during the Obama era and the Trump era,through the analysis of the Trump administration’s China policy in the economic,diplomatic,military and other major areas,grasping the new characteristics and new trends in the Trump administration’s China policy portfolio,and having a deeper understanding of the current US government’s strategic considerations,the nature of its China strategy,as well as the strategic identification of domestic political parties and all levels of society.These help us to study the specific causes of the changes in the Trump administration’s China policy.The adjustment of the US Trump administration’s China policy not only poses new challenges to the construction of a new type of major-power relationship between China and the United States,but also has a negative impact on the integration of global mechanisms and the operation of various regional orders.Although the stakeholders of the strategic competition strategy,the uncertainties that may exist in the future between China and the United States still need to expand the intersection of common interests and mutual influence. |
