Deepening Sino-Singapore International Relations under the Belt and Road Initiative: Synergistic Mechanisms in Multilateral Governance, Policy Innovation, and Public Administration

The Belt and Road Initiative (BRI) has not only facilitated deeper global economic integration but also fostered extensive cooperation among participating countries in governance, policy design, and innovation. As a global financial hub and a key strategic node in Southeast Asia, Singapore, with its advanced governance practices, robust financial system, and strategic geographic position, has established a close collaborative relationship with China under the BRI. From the perspectives of multilateral governance theory, new institutionalism, and digital public policy innovation, this study systematically explores the synergistic effects between China and Singapore in the fields of international relations, government governance, financial innovation, green development, and the digital economy. Through theoretical analysis and case studies, this paper not only unveils innovative practices in policy interactions between the two nations but also identifies challenges within the cooperation framework. Based on these findings, it proposes strategies to promote the sustainable development of BRI projects in the future.
