Japan, South Korea and the rise of a networked security architecture in East Asia

This article explains Japan’s and South Korea’s role in the transition from the hub-and-spokes alliance system to a networked security architecture in East Asia. It is argued that China’s contestation of the rules-based international order in East Asia has been confronted by East Asian states through a mixture of resistance and accommodation. From a Japanese point of view, Beijing’s ascendency is considered particularly disruptive for the regional order. Consequently, Japan has become a central hub in the development of the networked security architecture enacting two complementary strategies: the consolidation of the alliance with the United States and the creation of new and less binding forms of bilateral, minilateral and multilateral security partnerships with Asian allies. By contrast, since Seoul considers China as an essential partner for the stabilisation of the Korean Peninsula, it has played a more peripheral role in the development of this regional networking dynamic.
