Nine dashes, five judges, two contestants. It sounds like a reality television show. In fact, it is the rather obscure – but very important – beginning of a process to delineate fiercely disputed Asian maritime borders according to the rule of law, rather than the law of the jungle.
The nine dashes belong to China. They mark what Beijing says is its historical claim to most of the South China Sea, a vast waterway that borders several other Asian countries. The five judges have been chosen to sit on a tribunal that will determine the validity of that claim under the UN Convention on the Law of the Sea .
The two contestants are the Philippines, which brought the case, and China, whose nine-dash line is being challenged. Strictly speaking, there is only one contestant, since Beijing, though a signatory of Unclos, has not deigned to recognise the process.
