In the latest incident of maritime tensions between the Philippines and China, the Philippines has accused Chinese vessels of engaging in dangerous maneuvers within the disputed South China Sea region. The Philippine Coast Guard encountered eight Chinese boats during a routine rotation and resupply mission near Ayungin Shoal, also known as Ren'ai Reef. These Chinese vessels, which included four coast guard vessels and four maritime militia boats, posed a threat to the safety of the Philippine crew members.

This incident follows a prior dispute where Chinese coast guard ships allegedly used water cannons against Philippine vessels during a resupply attempt at the same shoal in the Spratly Islands. Western experts specializing in maritime security believe that China maintains a maritime militia consisting of hundreds of vessels, serving as an unofficial and deniable force to advance its territorial claims in the South China Sea. The Philippines asserts that this militia played a role in both recent incidents at Ayungin Shoal, an area with historical territorial disputes.

China claims indisputable sovereignty over a large portion of the South China Sea, including the Spratly Islands, which are also claimed or partially claimed by the Philippines, Malaysia, Brunei, and Taiwan. The Philippines refers to this area as the West Philippine Sea. In 2016, the Permanent Court of Arbitration in The Hague ruled in favor of the Philippines, stating that China lacked a legal basis for asserting historic rights over the majority of the South China Sea.

However, Beijing has disregarded this ruling, arguing that the Philippines had promised to remove a vessel grounded on Second Thomas Shoal in 1999 as a demonstration of their claim to the area. The Philippines' territorial claims have received support from the international community, but China has continued to oppose them. The recent incident has led the Philippine Coast Guard to reach out to its Chinese counterpart, urging them to cease any illegal activities within Philippine maritime zones. The ongoing tensions highlight the complex and ongoing disputes over territorial claims in the South China Sea.
