With an empirical focus on post-Cold War China¨CRussia relations, which represent the ambivalent combination of a consistently growing strategic entente and a simultaneous reluctance to form a full-fledged political-military alliance, this study establishes two major unit-level factors ¨C differing economic models and negative historical memories ¨C that create hurdles for alliance formation between the two countries. However, under greater systemic pressure from the US-led unipolarity, China¡¯s and Russia¡¯s state leaders have not only increased bilateral military-to-military cooperation but have begun to actively implement policies to deliberately transform, if not remove, the existing non-systemic hurdles. Therefore, the neoclassical realist framework can be understood and further tested as a dynamic interaction model in which the unit-level circumstances, while moderating the causal impact of the system, are themselves being transformed by the system via state policies, as is their impact on states¡¯ foreign policy %K China-Russia relations %K foreign policy %K neoclassical realism %U https://journals.sagepub.com/doi/full/10.1177/0047117818812561
