Philippines v. China (PCA Case No. 2013-19)

Philippines v. China (PCA Case No. 2013-19) was a legal case where the Philippines challenged China's claims in the South China Sea, particularly regarding the "nine-dash line" marking territorial boundaries. The Philippines argued that China’s claims violated international law, specifically the United Nations Convention on the Law of the Sea (UNCLOS). In 2016, the tribunal ruled in favor of the Philippines, stating China’s claims had no legal basis and that China had violated the Philippines' maritime rights. China rejected the ruling, maintaining its claims, leading to ongoing tensions in the region.
