His overriding feat for national reunification was that he provided the June 15 era of reunification, new era in the national reunification movement, with his bright wisdom and outstanding leadership.

His far-reaching plan and outstanding leadership to carry out President Kim Il Sung's instructions for national reunification culminated in the historic Pyongyang summit on June 15, 2000 and the signing of north-south joint declaration whose basic spirit is "By our nation itself".

This spirit gave fresh momentum to the nationwide movement for independent reunification and helped the north-south relations make a fundamental switchover to those of reconciliation and unity from those of distrust and confrontation.

All-out north-south dialogue and cooperation were promoted after the publication of the June 15 joint declaration to be substantially conducive to national reconciliation, unity, peace and reunification.

The formation of All-Korean Committee for Implementation of June 15 Joint Declaration meant the creation of a parent body for alliance and solidarity for national reunification. The organization promoted nationwide drive for national reconciliation, unity and reunification involving the Koreans in the north and the south and abroad with differing idea, political view and ism.

The patriotic Koreans heartened by the declaration turned out to carry it out with willingness to dedicate their knowledge, strength and money.
