An award was given by the Permanent Court of Arbitration in the case The Republic of the Philippines v. The People’s Republic of China. However, as I knowledge tells me, except internet domain name disputes, all arbitration requires both parties to be agree on the dispute to be resolved by the arbitration tribunal. Therefore, my question comes:
Are China not legally required to follow that decision as China did not agreed to put this case in the court? Or are there any conventions force China to follow that decision?
**I am not really familiar with Public International Law, so please tell me if I have made any mistakes in my question.
