The proposal in this paper outlines an idea for a Korean Peninsula focused Peace Cruise starting from Jeju World Peace Island and going up the eastern coast of the peninsula ， taking in a port or two in Japan (such as Fukuoka) to accommodate potential Korean-descended passengers there and ending at Wonsan, where a grove of Jeju King Cherry (Prunus Yedoensis var. Nudiflora) trees could be planted progressively as a welcome avenue for those on the peace cruise ship. This grove of Jeju King Cherry trees will grow each time a Jeju World Peace Island Peninsula Cruise arrives. Wonsan has been a holiday place for the DPRK for some time and with the permission of that country could become a limited and controlled international destination for Peace and, perhaps, other cruise tours. There are precedents internationally for special zones to be declared for specific activities. Such places frequently become economic development zones for the host country. After successful itineraries have been shown, the Jeju World Peace Island ship could extend its cruise north to ports on the Kamchatka Peninsula and west to Chinese ports interested in the concept
