The East China Sea is a part of Pacific Ocean and lies in the east of China. It opens into the Yellow Sea in north and Sea of Japan through the Korea Strait. To its south lies the South China Sea, while the Asian continent in the west. It is bounded by “Kyushu” and ‘Ryukyu’ islands of Japan in the east.Globally, the importance of East Asia region is increased and may become the New World-Centre in the future. To maintain a global network of trade and exchange relations the neighbouring countries communicate through the waters of East China Sea. However, this is not the modern way of integration into local and supra -regional networks. In earlier times, these waters acted as a medium to facilitate various kinds of exchanges and human activities. Private merchants, government officials and institutions used to maintain contacts with the world beyond the borders through this sea. In general aspects, the East Asian Maritime space was used for both commercial, military, diplomatic and private purposes such as migration and voyages. However lately, some disputes are arising related to the space of this Sea, as it borders: Japan, The People’s Republic of China, Republic of China (Taiwan) and South Korea.
