Chinese Coast Guard ships used water cannons and blocking maneuvers against Philippine vessels at Scarborough Shoal in the South China Sea.
These confrontations highlight the escalating territorial tensions between Manila and Beijing over maritime boundaries and fishing rights in the region. The incidents represent a pattern of aggression that threatens regional stability and the safety of civilian mariners.
Reports of the confrontations began on Aug. 25, 2024, when Chinese ships fired water cannons and blocked a Philippine fisheries vessel [1]. The situation intensified through September and October 2025 with further clashes [3, 4]. During one such encounter, Chinese and Philippine ships collided near the disputed shoal [3].
Other reports describe more severe tactics. The Chinese Coast Guard rammed and damaged a Philippine vessel off an island in the South China Sea [4, 5]. These maneuvers have resulted in physical harm to personnel, including a Navy serviceman [2].
In a separate incident involving water cannons, the Philippines reported that three [1] fishermen were injured [2]. The use of high-pressure water cannons is a frequent tactic used by Beijing to deter Philippine presence in areas it claims as its own territory.
The disputes center on overlapping territorial claims in the South China Sea [1, 3]. While the Philippines asserts its sovereign rights over its exclusive economic zone, China continues to deploy coast guard and militia vessels to enforce its own expansive claims.

The transition from blocking maneuvers to ramming and the use of water cannons suggests a shift toward more aggressive 'gray zone' tactics. By avoiding the use of lethal weaponry while still causing physical injury and structural damage, China can exert control over the South China Sea without triggering a full-scale military conflict. This puts the Philippine government in a position of having to balance its sovereign rights with the risk of further escalation.
