Abstract How did Russia, despite being in a weaker position, exercise a continuous and resilient influence on China's normative approach to international conflicts from Syria to Ukraine? This article proposes a theoretical framework that connects the affective turn and norm studies in International Relations. It conceptualizes emotions as the affective infrastructure of norm scripts: shared political feelings create resonance, based on which persuasive narratives work to maintain solidarity and institutionalize normative changes. Drawing on primary Russian and Chinese resources and using process tracing to identify critical junctures in the partnership and institutional channels for Russian campaigns, this article demonstrates how China's alignment with Russia is not solely based on geopolitical interests or constructed identities but rather a result of feelings of isolation and marginalization that firstly resonated with and then exploited by Russian actors. Furthermore, this article identifies three types of persuasive narratives used to construct continuity, analogy and identification in consolidating emotional resonance around the threat of a homogenous West and inducing normative convergence. This drives China to adopt policies in conflict with national interests and norms on sovereignty and territorial integrity that trigger a reflective assessment of the Russian influence, while underlining the growing importance of emotion diplomacy.
