The delimitation of maritime zones is an important requirement for peaceful relations between neighbouring States. There are numerous examples of areas between States with opposite or adjacent coasts where sovereignty over an island or territory may not be contested but the delimitation of the continental shelf and exclusive economic zone is still pending. Under the Law of the Sea Convention, the delimitation of these zones shall be effected by agreement on the basis of international law. However, the Convention does not offer a definitive answer as to the methods that should be applied. This publication includes contributions by Judges of the International Tribunal for the Law of the Sea, eminent scholars and experienced practitioners. The papers deal with various aspects of maritime delimitation: the jurisprudence of international courts and tribunals and their relevance for delimitation, the impact of the Law of the Sea Convention, the role of legal practitioners and diplomatic negotiators, and delimitation under particular geological circumstances and in geographically complex regional situations. It is designed to provide insight and guidance to the complicated process of maritime delimitation.

The settlement of the maritime boundary disputes between China and Japan in the East China Sea, and between Greece and Turkey in the Aegean Sea, is politically deadlocked. While diplomatic settlement efforts have been ongoing for the past several decades, neither side in each case appears prepared to back down from its respective maritime and territorial claims. Several incidents at sea have occurred, prompting diplomatic protests, military standoffs, even exchange of fire. The existing status quo is inherently unstable and does not favour either side to the extent that it holds hostage the multiple benefits that could otherwise be generated from the exploitation of the seabed energy and mineral resources in the disputed waters, creating an urgent need for a meaningful discussion on finding a practical way forward. This monograph undertakes a comprehensive analysis of these disputes based on the rules and principles of international law, critically evaluating possible institutional designs of inter-State cooperation over seabed activities in disputed maritime areas and makes recommendations for the prospect of realising joint development regimes in the East China Sea and the Aegean to coordinate the exploration for and exploitation of resources without having resorted previously to boundary delimitation settlement.

This key work analyses the disputes between Greece and Turkey as to their respective rights in the Aegean Sea, paying particular attention to the claims regarding territorial waters, the continental shelf, and the yet to be declared exclusive maritime zones in the area. While many earlier studies have concentrated on political factors, this study provides an exhaustive analysis of the relevant principles of international law in general and rules and principles of maritime law in particular, identifying the legal principles appropriate to the settlement of the Aegean dispute. With this regard, it makes a detailed examination of all the related aspects of the Aegean Sea and its islands, as well as the legal arguments of Greece and Turkey on the disputes concerned. It also clarifies the prospects for settling the dispute on the basis of international law, either by the two parties involved, or by the intervention of a third party such as the International Court of Justice. As such, it offers an important study of a particular problem, but one that can be used as a case study for other international disagreements.
