Fourteen nations plus the EU released a joint statement on Sunday. They echoed the 2016 arbitral ruling that overturned China's broad claims in the South China Sea. The signatories said these claims have no basis according to international law. This declaration marks the 10th anniversary of the ruling from a tribunal in The Hague. Beijing swiftly rejected the move. Chinese officials accused relevant countries of playing up the alleged arbitration award. The initial landmark case involved disputes between China, the Philippines, Vietnam, Malaysia, and Brunei. This joint push represents renewed pressure on Beijing. Tensions in the sea persist as the anniversary arrives. The joint statement highlights the continued rift over maritime rights in the region.
