The “Nine-dash Line” serves as a boundary established by China to outline its maritime entitlements in the South China Sea, an area abundant in resources and crucial shipping lanes. The line comprises nine dashed segments that enclose a large region, which conflicts with the Exclusive Economic Zones (EEZs) of neighboring nations such as Vietnam, the Philippines, Malaysia, and Brunei. This overlap is the main cause of disagreements, as these countries assert their own claims over parts of the same territory, resulting in diplomatic strains and disputes related to sovereignty and rights to resources. The unclear nature and historical context of the line further exacerbate the situation, rendering it a prominent source of international conflict.
