Although unification with North Korea, along with the related issue of national security, is South Korea’s core national objective, it is not a goal that Korea can pursue unilaterally. Support from the United States and China is necessary. This paper forecasts developments in Sino-American relations, nalyzes their implications for the Korean peninsula, and proposes policy options that will facilitate the peaceful unification of the two Koreas. Based on the prediction that the future of Sino-American relations will take the form of the extended status quo with periodic instability, I propose policy options that reflect China’s increased relative capability vis-à-vis American capability and utilize the concept of strategic pragmatism. Korea’s options include positive peaceful coexistence, deepened inter-Korean cooperation based on the wotrack strategy, peninsular arms control along with the institutionalization of Northeast Asian multilateral security cooperation, a modernized Korea-U.S. alliance, and upgraded cooperative relations with China.
