The international law of the sea is the oldest branch in traditional international law but also a fast developing branch in contemporary international law. After the entry into force of the UN Convention on the Law of the Sea in 1994, there have been considerable developments in the field of the law of the sea. Some provisions of the Convention proved to be inadequate, ambiguous or difficult for an effective implementation. This book attempts to reflect the latest developments in the law of the sea, including maritime dispute settlement, maritime boundary delimitation, non-traditional maritime security issues, and the impact of maritime powers such as the United States on the development of the law of the sea. While the book takes a holistic approach, it has made a special reference to East Asia, the most vibrant region in economic development and the most volatile place in maritime disputes in today’s world.
