This article is focused on some scenarios of a third way for Jeju Peace Island for Koreas as one of provincial government. In 2002 and 2006, We suggest United Three States of Korea : South Korea, North Korea and Jeju Island Korea. But in real situation Korean government chooses the Jeju Special Self-Governing Province. After practicing it 11 years, Jeju islanders are complaining it is not enough for them to improve its autonomy to push its policies on its way without empowering main authorities to local province from central government. So, they wants more power through revision of Korean Constitution as same as State government of USA and Switzerland such as guaranteeing special status of Jeju government as Hong Kong of China. In our opinion, in a word, Jeju islanders want to become “ Jeju Peace Self-Governing Province,” for two Koreas.
