Exclusive Economic Zone (EEZ) regime in East Asian waters : military and intelligence-gathering activities, marine scientific research (MSR) and hydrographic surveys in an EEZ

Abstract

Military and intelligence-gathering activities, MSR and hydrographic surveys in an

EEZ are problematic and controversial issues. There are at least two reasons for this

situation. Firstly, the unresolved territorial and maritime boundary disputes mean that

jurisdiction over an EEZ may be unclear. States may conduct all kinds of military

operations and marine research in areas that might be claimed by other states. Secondly, some of the key terms and key expressions to define and regulate these activities under the United Nations Convention on the Law of the Sea (UNCLOS) are

ambiguous. This creates opportunities for countries to interpret UNCLOS for their

own interest. In the past few years, some actual incidents have shown conflicts of

interest between different countries. This paper discusses the nature of these conflicts

and the main concerns of the opposing parties.
