The historic summit in Pyongyang of South and North Korea`s leaders makes a turning point in the relation between South and North Korea. Up to the present, South and North Korea have been at a war of attrition with mutual distrust and opposition, and it is a burden to the development of the nation. But the summit is expected to give a chance of solving the piled-up problems between South and North Korea. Also in the field of tourism, it is expected that South and North Korea interchange and cooperate with each other in earnest. The integrated development of Mt Sorak and Mt. Keumgang is being driven forward as the symbol of South and North Korea`s cooperation. For the integrated development, mutual complement of each resource is the most necessary condition. It is estimated that the range of Mt. Sorak is superior in the rear markets and accomodations of tourism because surrounding cities are well formed, while Mt. Keumgang is superior in the scenery and resource of tourism. Therefore, we must proceed to develop Mt. Sorak and Mt. Keumgang efficiently through distributing functions complementarily, i.e. recreation facilities to Mt. Sorak and natural resources to Mt. Keumgang.
