With regard to Ieodo, South Korea and China argue that Ieodo belongs to their territory respectively, considering its history. However, both parties haven't suggested concrete evidence to support their argument. Even if they suggest corroborative facts, they are distorted or exaggerated like myth. Therefore, it is important by what side primitive title and effective control are exercised in settling the problem of Ieodo. The issue was to suggest coherence logic by finding concrete geographical facts in the East China Seat the time of applying a method of boundary decision followed by the marine act, namely principle of median line and principle of equidistance. China has argued that China should occupy most of continental shelf in the East China Sea on the basis of silt, a deposit of the continent. However, the base of the East China Sea is a part of Eurasian Plate. In addition, a geographical contribution to formation of the continent shelf by the Korean Peninsula is equal to the Chinese Continent. Ieodo is 'Island of mythos' in China, but is 'Island of legend' suggested by concrete facts in South Korea. Therefore, its cultural titile and primitive title are belonged to South Korea, before its historical title.
