Abstract: The securitization of major-power relations refers to a country framing its economic, technological, cultural, and other interactions with other countries as security threats, and prioritizing security competition as the primary principle in handling bilateral relations. The securitization of major-power relations is shaped by three key factors: the strategic environment they face, their behavioral motivations, and interactions between the actors. The characteristics and interplay of these factors determine the trajectory of such securitization. Amid shifting power dynamics between China and the United States (US), with the US increasingly perceiving China as its primary strategic competitor, the US has adopted strategies of zerosum competition and exacerbated conflict in assessing the strategic environment, setting behavioral motivations, and choosing interaction patterns. This approach has led to risks of overextension and loss of control in the USs securitization of relations with China. In response, China must work to reverse the expansion of USdriven securitization of its relations with China in three aspects: reshaping security perceptions, enhancing dialogue mechanisms, and constructing a new strategic stability framework, thereby preventing bilateral relations from falling into a pansecuritization trap.
