中日韩合作的发展、困境与前景（英文）

China International studies 2024年第2期 41-68+2页

作者：巴殿君左天全 the center for Northeast Asian studies Jilin University the Institute for Northeast Asian studies Jilin University

China-Japan-ROK cooperation has witnessed significant progress in both depth and breadth with a comprehensive and multi-dimensional architecture. Despite the multiple practical challenges, the three countries do not retrogress from their will and vision to strengthen regional cooperation. Peaceful coexistence among the trio and their joint efforts to promote regional economic development and cultural integration are consistent with the three sides' national interests and the broader region's demand. This is also a precondition for win-win cooperation in Northeast Asia.
