The United Nations Conference on the Law of the Sea produced a Convention in 1982 through which maritime regionalization is to be peacefully organized. However, jurisdictional application of the Law of the Sea has not been easy. In this book the basic problems of regionalization are concisely described in relation to each area regime and the regulations of the new Law of the Sea. The development of maritime law in the Pacific region is summarized and the economic significance of these sea-areas is also clearly stated.
