Why has South Korea accommodated China, instead of fearing its growth and balancing against it? This article makes two central arguments. First, concepts of balancing and bandwagoning are fundamentally difficult to test, and to the extent that the theory can be tested, it appears to be wrong in the case of South Korea. In fact, we observe many cases in which rising powers are neither balanced nor “bandwagoned” but are simply accommodated with no fundamental change either way in military stance or alignment posture. Second, the factors that explain South Korean foreign policy orientation toward China are as much about interests as they are about material power. South Korea sees substantially more economic opportunity than military threat associated with China's rise; but even more importantly, South Korea evaluates China's goals as not directly threatening.
