Intensification of geopolitical instability has fundamentally reconfigured the structural foundations of Sino-Russian energy cooperation. Confronted with unprecedented Western financial sanctions and supply chain disruptions, bilateral cooperation has undergone a fundamental transition from simple quantitative expansion toward building institutional resilience. Through a comprehensive analysis of empirical data, including trade dynamics and joint project structures, this study reveals a system of three complementary and synergistic mechanisms underpinning this structural transformation: 1) strategic reconfiguration of infrastructure; 2) innovative instrumentalization of settlement mechanisms; 3) institutionalized integration based on equity participation. The development of pipeline networks, such as the Power of Siberia, and Arctic liquefied natural gas (LNG) projects has not only diversified supply sources but also driven a strategic redistribution of global energy flows, effectively mitigating geopolitical risks associated with traditional transit routes. The Renminbi payment system has evolved from a crisis-response tool into a complete, institutionalized financial infrastructure; its share in energy settlements has grown, effectively hedging sanction risks and systematically reducing reliance on the US dollar system. In strategic projects like Yamal LNG and Arctic LNG 2, the Chinese side, through tiered equity participation models, has secured shared governance and internalized risks, elevating the level of cooperation from transactional relationships to strategic co-management. The research demonstrates that these interlocking mechanisms successfully convert external pressure into internal structural resilience, collectively establishing an independent Arctic-Northeast Asia energy corridor. This study provides a replicable analytical model and practical paradigm for emerging economies confronting geopolitical fragmentation, illustrating how infrastructure sovereignty, currency instrumentalization and co-governance architectures offer a viable alternative pathway for constructing a more resilient energy security system independent of US dollar hegemony. The findings are of interest to corporate executives involved in China-Russia energy cooperation and to academic researchers studying international energy cooperation within a shifting geopolitical landscape.
