As the international system transitions from a unipolar structure to a multipolar world order, China’s growing global influence has become a focal point of diplomatic analysis. This research explores the changing dynamics of global politics by examining state voting alignments with China within the United Nations General Assembly (UNGA). Moving beyond aggregate voting metrics, the study employs a mixed-methods approach—combining quantitative network analysis with qualitative evaluations of Chinese foreign policy—to demonstrate that China’s diplomatic network is highly issue-dependent rather than a monolithic political bloc. Specifically, the findings reveal that states are highly likely to align with China on foundational issues such as sovereignty, colonialism, Middle East affairs, and economic development, which are driven by shared normative values and material interests. However, this coalition fragments significantly when addressing hard security issues and nuclear disarmament, where states instead choose to prioritize their own strategic autonomy. Ultimately, this issue-specific flexibility illustrates that contemporary multipolarity is defined by adaptable, overlapping partnerships rather than rigid, Cold War-era alliance structures, highlighting a nuanced shift in global governance.
