Adding further complexity?: Extended Continental Shelf Submissions in East and Southeast Asia ( (NBR Special Report no.37, pp61-78)

Recently, several regional states have submitted information on their outer continental shelf limits to the CLCS. The submissions made by coastal states in the region overlap with the maritime claims of neighboring states. This is in large part a consequence of the fact that such submissions encompass areas where territorial and maritime disputes still exist, such as the maritime areas in the vicinity of the Senkaku/Diaoyu Islands in the East China Sea and the Spratly Islands group in the South China Sea. Accordingly, these submissions appear to add a further source of discord to the already highly complicated and contentious situation in the region due to preexisting territorial and maritime disputes. This view is supported by the fact that extended continental shelf submissions have incited a series of protests and counterprotests on the part of interested states. At the same time, however, these submissions, and the reactions that they have provoked from interested states, offer fresh insights and assist in the interpretation of previously unclear maritime claim
