Although the investment environment has changed rapidly due to the war, Russia is still a region with abundant fisheries resources and development potential. Russia is composed of a structure in which the global supply chain of fisheries products is processed in neighboring countries and distributed around the world due to the lack of advanced fisheries environment. Russia has established a “Russian Fisheries Development Strategy 2030” plan to solve this chronic problem. The reason why investment in the fisheries sector has been low in Russia is that Russian fishing companies have been able to export to China at good prices as raw materials without processing, and China has been able to increase added value by utilizing cheap workers. However, after the pandemic, the weaknesses of these business models were revealed. After the pandemic, Korea’s opportunity factors clearly exist in the process of cracking the global supply chain of seafood through China and changing existing business models. Currently, it is slowing down due to the war, but in the long run, investment by the Korean government and private companies in the fisheries sector in Russia’s Far East will increase. This study will help managers and policy authorities make decisions by conveying implications for entering the Russian fisheries sector to Korean companies and the government.
