The Philippines marks ten years since an arbitration ruling over the disputed South China Sea

Territorial disputes in the South China Sea is far from over. A landmark ruling ten years ago - invalidating most of Beijing's nine-dash line claims, doing little to bring contesting states to an agreement. China boycotted proceedings and has never recognised the verdict. But for Manila - the ruling serves as a valuable cornerstone of order rooted in a rules-based international order. The ruling is also the basis for a Code of Conduct for China and other claimants. Dr Collin Koh - Senior Fellow at the Institute of Defence and Strategic Studies at RSIS joins us for more.
