ASEAN as a regional organization in Southeast Asia has cooperative relations with state actors and other international organizational actors within the ASEAN+1 framework, one of which is with South Korea. ASEAN relations with South Korea experienced ups and downs due to following the dynamics that occurred on the Korean Peninsula. After the election of Moon Jae In as President of South Korea, the South Korean government emphasized its seriousness to deepen its relations with countries in Southeast Asia and India. This article explains why South Korea has again strengthened its relationship with ASEAN through the New Southern Policy. This study uses the concept of national interest based on English School thinking with a qualitative approach and literature review methods that collect data in the form of books, journals, official government websites, and scientific reports/papers.
