The Impact of China’s Industrial Structure Adjustment on Trade and Technological Cooperation between China and the Eurasian Economic Union

China's industrial structure has undergone profound transformation in recent decades, shifting from a reliance on labor-intensive production to innovation-driven and high-tech sectors.This restructuring has reshaped the country's external economic relations, particularly with the Eurasian Economic Union (EAEU), a regional integration bloc that serves as a strategic partner for China.This study examines how China's industrial upgrading influences bilateral trade dynamics and the development of technological cooperation mechanisms with the EAEU member states.Using a multidisciplinary approach combining trade statistics, policy analysis, and case studies of collaborative projects, the paper highlights the evolving complementarities between China's advanced manufacturing and digital economy sectors and the EAEU's energy, raw material, and transit advantages.The findings suggest that industrial adjustment in China stimulates demand for diversified imports, while also promoting the export of high-value-added goods and services.Additionally, the transition toward green and digital industries has fostered new platforms for scientific collaboration, infrastructure development, and technological innovation across Eurasia.However, the research also identifies challenges, including regulatory disparities, unequal technological capacities, and geopolitical tensions that may impede the depth of cooperation.Overall, the study argues that the modernization of China's industrial structure is both a driver and a test for the sustainable growth of China-EAEU economic and technological relations, with long-term implications for regional integration and global value chain participation.
