The main thesis of this paper is "the Sunshine policy and the political change of North Korea."The Following are a few issues to be taken up in conjunction with this study. Firstly, one must consider on how North Korea is responding of the current Sunshine policy. Secondly, besides the official response of the North Korean government actually takes in the Sunshine policy should also be studied. Lastly, the adequate usage of the specific terms relating to this study should be reviewed in advance. This must begin with the consideration of how the terms such as "Sunshine policy" and "North Korea Engagement policy" could be relatively established for this study. The main framework of the "Sunshine policy" rest on the concept of cooperative existence of both nations in the Korean Peninsula. Therefore, I believe that strategic transition from the "Sunshine policy" to "North Korea Engagement policy" need not have taken place if the former policy had well balanced its scope of radiation. That is to say, the "Sunshine policy" would have seen more light if only it had focused its radiations not only on Pyongyang itself but also on the Cold Peace atmosphere that had been prevalent in the Korean Peninsula since the advent of the Cold War. When outlining these policy issues through the views of the above thesis, consideration of the following viewpoints should be made. Firstly, given the fact that North Korea is exhibiting oversensitive reactions, it seems clear that they are burdened by South Korea`s “Sunshine policy.” Secondly, while expressing its denunciations as it tries to remain out of limit from the policy, North Korea simultaneously has shown unprecedented change in attitude to accumulate economic profits that arise from the "Sunshine policy" Lastly, "Sunshine policy" has influenced North Korea`s foreign relations in various aspects. To conclude, it seems early to discuss the fruits of "Sunshine policy" at the present stage of its implementation. However, taking into consideration of various aspects of the policy, it is safe to project that it still has a high possibility of eventually yielding practical and effective outcomes. This is so, because the development of North-South relations rests not on a transitory arena but in a perpetually reproductive and continuous arena of contestation. To be more precise, this is due to its strong "Ecological Tournament"-like disposition. Therefore, based on the arguments that I have forwarded, whether the "Sunshine policy" would indeed act as a catalyst to transform the North-South relations from a `hostile dependence` phase and to a new phase of `dependent cooperation` should be throughly and objectively reviewed.
