What is contested
The line appears on PRC maps around most of the South China Sea. Its exact legal character has been contested, while neighbouring coastal states assert maritime entitlements under UNCLOS.
Legal position
The 2016 Annex VII tribunal found no legal basis for PRC historic rights to resources beyond the maritime zones allowed by UNCLOS. It did not decide sovereignty over land features or delimit maritime boundaries. China rejects the award as null and void.
Why it matters
It overlaps vital sea lanes, fishing grounds, possible energy resources and several coastal states’ claimed exclusive economic zones.
Political geography uses Natural Earth 1:10m data. The nine dash segments were redrawn against the 5-degree graticule in Figure 2 of the South China Sea Arbitration Award, reproducing the map attached to China’s 2009 UN notes CML/17/2009 and CML/18/2009. Endpoint positions remain approximate at this display scale. The line is a claim depiction, not an agreed maritime boundary. Feature markers are approximate and sized for visibility. This educational map does not take a position on sovereignty.
