The Typology of International Politics for New Cold War: Tracing the Relevance of Middle Power Diplomacy and South Korea’s International Politics Based on Advanced Strong Power

States, formerly classified as a middle power, have stepped up the level to engage in international politics and preserve international order by strengthening solidarity. If then, is the discourse of middle-power diplomacy still relevant? This paper proposes the typology of international politics for the New Cold War by linking a materialistic variable with a value-fusion variable in an effort to answer this puzzle. As this framework lays out nine types of states, the need to reclassify middle power to advanced strong power is observed analytically. Meanwhile, it comes up with five factors: recognition of international situations, behavior, preferred platform, and scope of combined formation. Two cases are examined with these five factors: Canada, Australia, and Japan as the first case and South Korea as the second case. Finally, this paper provides academic and policy implications. Academically, it sheds some light on the sustainability of this behavior and the scholarly expansion of middle-power diplomacy. It also suggests required policies such as tailored policies for advanced strong power, the expansion of South Korea's contributionled diplomacy and solidarity formation and the sustainability of universal value.
