Koreas Reach Agreement On Peace, Prosperity and Unity
The document from the North-South Korean Summit refers to the "Korean nation" when discussing the two Koreas. They describe their existence as "resulted from the division of the nation." They see themselves as one nation divided by outside forces and repeatedly describe efforts to seek unity.
The agreement also makes it clear they will decide the future of the Korean Peninsula, e.g. they state "South and North Korea affirmed the principle of determining the destiny of the Korean nation on their own accord . . ." Is that a diplomatic message to the superpowers on their borders, China and Russia as well as the United States that it will be Koreans who determine their own future. Korea has been a pawn in the conflicts between superpowers for much of its history since WW II.
When it comes to the military conflict they agree to "cease all the hostile acts against each other in every domain including land, air, and sea, that are the sources of military tension and conflict."
