There were four critical undercurrents for the growth of Korean think tanks in the 1990s: democratization, the end of the Cold War, globalization coupled with local autonomy, and the expanded government budget accompanying Korea’s rapid economic growth. In contrast to American think tanks which are private but normally serve as public policy advocates, most of the important Korean think tanks are supported by the government and they are not independent public policy advocates. The Korean public think tanks are highly susceptible to domestic political dynamics: for instance, the presidential office’s power over the appointment of the directors. The susceptibility originates not only from the delayed democratic institutionalization of the Korean presidential system but also from the absence of financial independence, limits to the accessibility of information on policy, and the lack of professionalism in the bureaucracy. The Korea Institute for National Unification, an exemplary public think tank regarding the issue of inter-Korean relations, now focuses on research and analysis rather than policy advocacy. Alternatively, it acts as a producer of knowledge and vocabulary to envision an epistemic community for deliberating strategies of engaging with North Korea.
