The Indo-Pacific region is experiencing dramatic geopolitical transformations, marked by the rise of China, intensifying great power rivalry between the United States and China, and the existence of numerous flash points for open conflicts due to geopolitics, geostrategic, and geoeconomic differences. Amidst these developments, the region also offers opportunities for cooperation, especially in the domain of non-traditional security challenges (NTS). As a contested region, Indo-Pacific also sees the rise of multiple forms of minilateralism, such as the Quadrilateral Security Dialogue (Quad), which has changed significantly from its early focus as a security grouping aimed against the perceived threat from China, by developing a much broader public goods agenda to deal with NTS challenges. This article examines how Indonesia’s foreign policy has responded to the growth of minilateralism in the Indo-Pacific region under the administration of Joko Widodo (2014–2024), especially looking at the government’s changing attitude towards the Quad after its transformation. This paper uses a qualitative approach, gathering and analyzing data from primary and secondary sources. The paper utilizes a theoretical framework from Non-Traditional Security (NTS) issues as the enabler for regional cooperation. By analyzing domestic and international factors pertaining to Indonesia’s foreign policy, this paper argues that the transformation of the Quad has helped to change the perceptions of the Joko Widodo’s government about the Quad from skeptical into becoming more open minded, which open opportunities to foster regional cooperation, stability, and resilience. The paper evaluates the Quad’s ability to support Indonesia’s national interests and a more equitable Indo-Pacific order by analyzing the opportunities and challenges that come with its evolution.
