From the first day of the country's division Kim Il Sung set it as the supreme task of the nation to reunify the country and consistently adhered to the line of one Korea, the line for reunification. He put forward the proposal for founding the DFRK, the most realistic one suited to the desire of all Koreans for reunification and the specific conditions of Korea, and brightly indicated the way of national reunification, the memorandum said, and went on:

He advanced the DFRK proposal on October 10, Juche 69 (1980).

According to the proposal for founding the DFRK, the country should be reunified by founding a Federal Republic through the establishment of a unified national government on the condition that the north and the south recognize and tolerate each other's ideas and social systems, a government in which the two sides are represented on an equal footing and under which they exercise regional autonomy with equal rights and duties.

The proposal comprehensively indicates the issue of founding a reunified country including the principle and ways of building a federal state, nature and function of a federal state and duties of a unified government and regional governments and their co-relations.

The best way of reunifying the country as soon as possible is to found a reunified country through federal formula based on one nation and one state, two systems and two governments.

No sooner had the proposal been published than it aroused full support and approval of all Koreans in the north, the south and abroad and the international community.

Kim Il Sung wisely led the struggle to carry out the proposal.

In his famous work "10-Point Programme of the Great Unity of the Whole Nation for the Reunification of the Country" in April, 1993, he clearly clarified once again that a pan-national reunified state should be built to represent all members of the nation irrespective of party and group affiliation and strata, leaving the two systems and two governments in the north and the south as intact.

He worked heart and soul to provide internal and external circumstances favorable for realizing the reunification through federal formula till the last moments of his great life.

The memorandum said that leader Kim Jong Il powerfully aroused all Koreans to realizing the cause of national reunification. It continued:

He published his work "Let Us Carry Out the Great Leader Comrade Kim Il Sung's Instructions for National Reunification" on August 4, 1997, formulated the three principles of national reunification, the 10-point programme for the great unity of the whole nation and the proposal for founding the DFRK advanced by Kim Il Sung as the three charters for national reunification which integrally systematize and consummate the fundamental principle and ways of national reunification and clearly indicated the issues arising in carrying out the proposal for reunification through federal formula.

In 2000, in which fell the 20th anniversary of the proposal for founding the DFRK, he provided the north-south summit for the first time in the history of national division and brought about the June 15 joint declaration, the landmark for national reunification in the new century, to Koreans, an event to be specially recorded in national history.

He powerfully aroused the whole nation to the struggle to implement the June 15 joint declaration.

He provided again the historic north-south summit in Pyongyang in October 2007 and performed undying feats by making sure that "the Declaration for Development of North-South Relations and Peace and Prosperity", the programme for implementing the June 15 joint declaration, was published.

The memorandum said that the cause of national reunification is greeting a new epochal phase thanks to the wise leadership of Marshal Kim Jong Un, adding:

In the New Year Address he clarified the principled stand of the DPRK to make a new advance in the movement for national reunification true to the behests of Kim Il Sung and Kim Jong Il this year marking the 20th anniversary of the last autographs left by Kim Il Sung on the historic document on national reunification, and the ways for carrying out it.

The north and the south, in the June 15 joint declaration, recognized that there is commonness in the north-proposed low-level federation and the south-proposed confederation for national reunification and agreed to work for reunification in this direction. The south Korean authorities should respect the joint declaration, work hard to carry it out and thus positively respond to the aspiration of all Koreans for reconciliation, unity and peaceful reunification.
