(VOVWORLD) - On July 12, 2016, the Permanent Court of Arbitration, the arbitral tribunal constituted under Annex VII of the United Nations Convention on the Law of the Sea in The Hague, issued a landmark ruling on the Philippine’s law suit against China regarding the South China Sea, known as the East Sea in Vietnam. Five years later the situation in the East Sea remains unresolved. But it’s undeniable that, together with the 1982 UNCLOS, the PCA’s ruling is an important legal foundation for resolving the East Sea disputes peacefully and ensuring maritime order.
