The ASEAN and ROK have played a crucial role in fostering regional peace and economic development. Nevertheless, the recent strategic competition between the US and China has turned the region into a contested arena. The relationship faces challenges due to the ROK's growing alignment with the US, prompting a rising interest in minilateralism as an alternative collaboration model. This paper scrutinizes the impact of ROK's foreign policy behavior, with a focus on minilateralism as a preferred cooperation model with ASEAN. The study centers on BIMP-EAGA, investigating its effectiveness in sustaining collaboration amid geopolitical rivalry. The paper concludes that BIMP-EAGA, as a manifestation of minilateralism, serves as an alternative platform for ROK and ASEAN cooperation. However, the study reveals that the implementation of BIMP-EAGA falls short of expectations. This paper emphasizes the need for greater subregional focus and comprehensive coverage of BIMP-EAGA to truly reflect the shared interests of ASEAN member states.
