Troubles under the water: Sino‐japanese conflict of sovereignty on the continental shelf in the East China sea

The discovery and production of offshore hydrocarbon resources are significant for both China (PRC) and Japan in meeting energy requirements for higher economic development. Because the claims of both countries to the continental shelf in the East China Sea overlap, there is a maritime conflict which hinders cooperation in the Asian region. The paper briefly describes the geographical characteristics of the East China Sea. It then dwells on the development of the legal criteria for delimiting continental shelf boundaries by examining major cases of international adjudication and both the 1958 Geneva Convention on the Continental Shelf and the 1982 Convention on the Law of the Sea. After presenting both countries’ positions the author attempts to review and analyze certain options which can be employed in resolving the sovereignty conflict.
