Many of the maritime disputes today represent a competing interest of two groups: coastal states and user states. This edited volume evaluates the role of the United Nations Convention on the Law of the Sea (UNCLOS) in managing maritime order in East Asia after its ratification in 1994, while reflecting upon various interpretations of UNCLOS. Providing an overview of the key maritime disputes occurring in the Asia Pacific, it examines case studies from a selection of representative countries to consider how these conflicts of interest reflect their respective national interests, and the wider issues that these interpretations have created in relation to navigation regimes, maritime entitlement, boundary delimitation and dispute settlement.
