Northeast Asia is usually associated with conflict and war. Out of the five regional order transitions from the Sinocentric order to the present post–Cold War period, only one was peaceful, the Cold War to post–Cold War transition. In fact, the peaceful transition led to a state of minimal peace in post–Cold War Northeast Asia. As the chapter discusses, this was due to three realist-liberal factors: America’s hegemonic role, strong economic interdependence, and a stable institutional structure. These factors not only ensured development and prosperity but also mitigated the negative effects of political and strategic tensions between states. However, this minimal peace is in danger of unraveling. Since 2010, the region is arguably in the early stages of another transition fueled by the worsening Sino-US competition. While the organizing ideas of liberal internationalism—economic interdependence and institutional building—will remain resilient, whether or not minimal peace is sustainable will be determined by the outcome of the US-China competition.
