Who’s Claiming What?

Explore the web of overlapping maritime claims in Asia. Click a country on the list to toggle claim lines. View specific information about claim lines by hovering and clicking. All claims depicted are based on a country’s international agreements, domestic legislation, and public submission of claims.

No maritime entitlements are shown from effectively dormant territorial claims, such as those of Taiwan over mainland China or the Philippines over North Borneo, unless they have been expressly declared.

In the South China Sea, maritime entitlements from the Paracel and Spratly Islands are not shown due to a lack of clarity about what each country claims. This will be updated as more clarity is given. China’s nine-dash line and Taiwan’s U-shaped line in the South China Sea are depicted, but not categorized as a specific type of claim due to their continued ambiguity.
