Production capacity cooperation is the heart of Lancang-Mekong Cooperation (LMC) in pursuit of common regional prosperity and synergized development. Such goals were enshrined in the Joint Statement on Production Capacity Cooperation among Lancang- Mekong Countries in 2016. A new initiative called “Multi- Nation, Multi-Park,” based on the experience of the China- Malaysia “Two Countries, Twin Parks” model, was launched at the 3rd LMC Leaders’ Meeting in August 2020. The leaders involved in designing the plan hold high expectations for its power to promote investment, create jobs, build capacity, reduce poverty, and foster technical and innovation cooperation.
