This study examines the potential for industrial cooperation between Korea and Viet Nam by quantitatively analyzing the structure of the sericulture industry and trade data from both markets. The findings reveal that Viet Nam, primarily focused on raw silk (HS 5002), holds a dominant position in the supply side of the sericulture industry. In contrast, Korea, despite its smaller market size, maintains consistent import demand and shows a concentration in exporting silk fabrics (HS 5007). Additionally, the sericulture industry has recently expanded into high value-added applications such as medicine, food additives, and cosmetics, indicating a trend toward industrial diversification. Based on these insights, this study proposes sustainable cooperation strategies between Korea and Viet Nam in sericulture, emphasizing trade expansion, technological collaboration, and integration with Official Development Assistance. These strategies aim to foster a future-oriented model of industrial cooperation between the two countries.
