The core of the foreign policy of Moon Jane’s government is the foundation of the “Peace Process of the Korean Peninsula”. At the center of the system configuration, it starts from East Asia, and the core of East Asia starts from ASEAN. This paper argues that cooperation with ASEAN is important for the completion of the establishment of the “Peace process of the Korean Peninsula”. In order to expand cooperation in various fields such as di-plomacy and economy, we must overcome obstacles such as re-authoritative coin tendency. The Moon Jane government named it “New Southbound Policy”. However, in fact, there have been no cases where past policies have promoted Southbound policy. Therefore, an approach for new policy establishment is needed, and we will present an effort to construct various cooperation programs.
