Fourteen countries plus the EU issued a joint statement on Sunday. They echoed the 2016 arbitral ruling that invalidated China's sweeping claims in the South China Sea. The signatories said these claims have no basis under international law. This declaration marks the tenth anniversary of the ruling from a tribunal in The Hague. Beijing swiftly rejected the move. Chinese officials charged involved countries of inflating the so-called arbitration award. The original 2016 case involved disputes between China, the Philippines, Vietnam, Malaysia, and Brunei. This unified push represents renewed pressure on Beijing. Tensions in the sea persist as the anniversary arrives. The joint statement highlights the continued divide over maritime rights in the region.
