The middle power notion has resurfaced as one of the key analytical terms in modern international relations, especially when it comes to the discourse of regional order in the context of great power rivalry and systemic uncertainty. With an increasingly fragmented and multipolar world order, the role of middle powers as potential stabilizers, coalition builders, or norm entrepreneurs who can influence the dynamics of the region without the huge material capabilities is frequently discussed (Cooper, Higgott, and Nossal 1993; Acharya 2014). In this context, India and South Korea are often collectively referred to as the middle power in Asia which possesses common features such as the economic potential, diplomatic range and the sensitivity to the strategic autonomy. But even when it seems that they come together, their policies toward regional order still have significant differences, which are not well studied in comparative studies.
