The purpose of this study is to analyze the factors affecting the import and export of agricultural products between Korea and ASEAN, and to derive cooperation plans in the agricultural sector. With the introduction of the Korea-ASEAN Free Trade Agreement (FTA) in 2007, economic cooperation has been expanded. From 2007 to 2021, Korea's foreign direct investment (FDI) to ASEAN countries increased by about 7.55% annually. As ASEAN has emerged as an important economic partner, cooperation in Official Development Assistance (ODA) has also strengthened. Between 2007 and 2020, the size of Korea's ODA to ASEAN countries also increased by about 11.63% annually. To prove the relationship between trade values in the agriculture sector, FDI and ODA, the gravitational model was used. As a result of the analysis, it was found that FDI and ODA affected agricultural trade. The results imply that cooperation in the agricultural sector between Korea and ASEAN should be made through the establishment of “trade (agricultural product trade)-cooperation (ODA)-investment (FDI) Nexus.”
