The South China Sea Maritime Tracker

This map depicts each claimant's territorial occupancies and internationally submitted sovereign rights and jurisdictional claims featured in national legislation with regard to the South China Sea. Click on a feature to learn more about each individual claim.

The United Nations Convention on the Law of the Sea ( UNCLOS ) provides an  unofficial table of claims to maritime jurisdiction  for additional reference.

The baseline and territorial sea limit claims of China, Indonesia, Malaysia, and the Philippines have been reduced to show the claims only in the South China Sea. See each country's maps for more detail on these alterations.

A representation of each claimant's exclusive economic zone is provided for additional reference on its claims. No claimant has publicly demarcated its EEZ, so this current representation may be subject to change.

The EEZ rights claims of Vietnam, Indonesia, China, Malaysia, and the Philippines have been cut off in various areas in order to place a greater emphasis only on claims in the South China Sea. See each country's maps for more detail on the cutoffs.

In areas where maritime boundaries are in dispute, we show the claims of each party based on the best publicly available information. ICAS emphasizes that these maps are not to be taken as an endorsement of any one party's respective claims over another's.
