The United States, the United Kingdom and 12 other countries reassert that China’s expansive claims in the South China Sea are illegal, pointing to a 2016 arbitration decision. In a joint statement, the countries say they reject actions they describe as destabilizing in the disputed waters and which they say threaten regional peace. The statement marks the July 12, 2016 ruling by a tribunal in The Hague established under the United Nations Convention on the Law of the Sea. The tribunal’s decision is described as final, legally binding and definitive. The case arose after the Philippines initiated arbitration in 2013 following a tense confrontation in the region, during which China effectively took control of a disputed shoal. China did not participate in the arbitration and continues to reject the ruling, asserting its position and defending claims over large parts of the sea, a major shipping route. The South China Sea remains a recurring flashpoint, with repeated territorial and maritime standoffs reported across the area.
