China’s Coast Guard and maritime militia have turned the South China Sea into a theatre of intimidation, employing ramming, high-pressure water cannons and dangerous blocking manoeuvres against Philippine and Vietnamese vessels with alarming regularity. These Gray-zone tactics aggressive yet below the threshold of war represent a systematic campaign to erode the sovereignty of smaller nations and enforce illegal claims rejected by the 2016 PCA tribunal.
Incidents in 2024-2026 highlight the pattern: Chinese vessels have repeatedly rammed Philippine resupply boats near Second Thomas Shoal, fired water cannons causing injuries and damage and used knives or lasers against fishermen. Similar harassment targets Vietnamese boats and exploration ships. These are not isolated accidents but coordinated operations by a vastly superior force designed to exhaust and deter Southeast Asian claimants from exercising their rights.
This bullying stems directly from China’s rejection of international law. By claiming waters deep within other nations’ EEZs as its own, Beijing uses its massive Coast Guard fleet the world’s largest as a paramilitary tool. The maritime militia, disguised as fishing boats, adds deniability while swarming and obstructing targets. Such actions inflict real harm: injured sailors, damaged vessels, disrupted fishing livelihoods and heightened risks of miscalculation leading to war.
Critics condemn this as predatory behaviour unfit for a supposed global power. While China portrays itself as a peaceful developer, its actions reveal a bully exploiting asymmetry. Smaller navies and coast guards cannot match China’s numbers and firepower, forcing reliance on diplomacy and U.S. support. This erodes regional trust and fuels an arms race as victims bolster defences. Environmental and humanitarian costs compound the aggression. Water cannon blasts damage equipment and endanger lives at sea, while blocking manoeuvres risk collisions in busy waters. China’s claims of “law enforcement” ring hollow when its targets operate in internationally recognised zones. The 2016 ruling explicitly affirmed Philippine rights; China’s response has been escalated coercion.
International responses, including U.S. condemnations and joint exercises, have offered some deterrence, but Beijing persists, testing resolve. Its strategy aims to normalise dominance, gradually pushing neighbours out and establishing control through presence rather than negotiation. This violates UNCLOS duties for safe navigation and peaceful dispute resolution. China’s tactics reveal a strategic calculus: incremental gains without triggering full alliance intervention. Yet they backfire diplomatically, unifying opposition and highlighting Beijing’s disregard for norms. ASEAN nations, though economically tied to China, increasingly voice concerns. The Philippines’ resilience, backed by mutual defence commitments, challenges this coercion. In sum, China’s ramming and cannon assaults exemplify reckless power projection that prioritises dominance over coexistence. They destabilise a vital global common, threaten lives and undermine peace. The international community must impose costs through sanctions, enhanced patrols and legal actions to curb this bullying. Without pushback, China will continue carving up the SCS, turning shared waters into a zone of fear and subjugation. This aggression is not strength but a sign of insecurity and contempt for its neighbours’ rights.
