Exploring the Optimization of International Trade Cooperation Path Based on The Belt and Road Initiative

International trade cooperation and outward investment are the core driving forces of global economic development, but they face multiple challenges such as insufficient effectiveness of multilateral mechanisms, fragmented regional rules, and high geopolitical risks. As the worlds largest developing country, the Belt and Road Initiative (BRI) in China is fundamentally based on the historical heritage of the ancient Silk Road civilization, integrates contemporary geo economic logic and the needs of global value chain reconstruction, and forms a unique theoretical paradigm. The BRI is not only an upgraded version of China's opening up but also provides a Chinese solution for the reshape of the global governance system and solving the development deficit. In the future, based on the theoretical and practical innovation of the BRI, each country is going to be committed to the upward trend of the global economy towards a more inclusive and resilient direction by deepening regional cooperation, improving risk management and guiding sustainable investment.
