This volume introduces principles and practices of ocean law by discussing particular issues of major concern for less developed states. It maps the development of these issues and how they have influenced the ocean policies of the states in East Asia, especially China. In addition, the book examines the major non-living resource in the area - oil - as geological surveys predict enormous offshore oil deposits. In an attempt to extend their boundaries to include as much of the rich seabed as possible, the East Asian states are involved in disputes over boundary methods, island claims, and exploration rights. This work also examines management and development of the living resources, as food supplies are depleted by rapidly growing populations and marine pollution. It looks at the concerns of effective national security, involving freedom of navigation and movement. The final chapter concludes by reassessing underlying assumptions in international ocean policy and Chinese ocean policy, and the new focus on the oceans that centred on the 1982 Law of the Sea Convention.
