[Health cooperation under the "Lancang-Mekong Cooperation 2.0" framework: a decade of retrospection and prospective outlook].

Since the launch of the Lancang-Mekong Cooperation in 2015, a core platform for regional health governance has been established. This paper systematically deconstructs 28 multilateral official documents issued between 2015 and 2024 by using policy text analysis to trace the logical trajectory of Lancang-Mekong health cooperation's development from project-driven initiatives to institutionalized governance. The study concludes that major public health emergencies within the region is the key factor to improve the institutional development and resource allocation of the system. This has expanded the cooperative agenda from initial joint prevention and control of infectious diseases to a comprehensive governance framework encompassing health service delivery, human resources, information systems, pharmaceutical products, health financing, and leadership and governance. By systematically analyzing achievements in building the six cornerstones of the health system, this paper reveals the platform's systemic integration advantages and collaborative governance effectiveness in addressing complex challenges. Based on the strategic requirement for quality enhancement and upgrading under "Lancang-Mekong Cooperation 2.0", this paper suggests continuing the efforts to improve the linkage between "water and health", fully implement the "One Health" approach, and accelerate digital health transformation to build a more resilient regional health community.
