Chinese warship Collision Fuels South China Sea Tensions
Growing Risks in the South China Sea
The latest incident in which a Chinese Navy warship collided with a Chinese Coast Guard vessel has reignited global concern about South China Sea naval tensions. The accident occurred Aug. 11, when both ships manoeuvred aggressively against a Philippine vessel near disputed waters. Analysts fear this highlights how close the region is to a major crisis.
The collision left the bow of the Chinese Coast Guard ship smashed, while the fate of sailors on deck remains undisclosed. Instead of acknowledging its mistake, Beijing has blamed Manila despite video evidence showing the Philippine Coast Guard ship attempting to evade harassment. The episode underscores how China’s confrontational tactics endanger both rivals and its personnel.
Dangerous Seamanship and Escalating Confrontation
According to Euan Graham, of the Australian Strategic Policy Institute, the collision was a direct result of reckless manoeuvring. He noted that the Chinese Coast Guard abruptly cut across the Philippine vessel’s wake, placing itself in the path of the People’s Liberation Army Navy (PLAN) ship. The outcome, he argued, was China “wearing the consequences of its own dangerous seamanship.”

This behaviour, Graham stressed, is further evidence that the South China Sea’s naval tensions could quickly escalate into a broader military and diplomatic crisis. By endangering smaller vessels, Beijing risks not only confrontation with Manila but also international condemnation.
Coordination Failures Between PLAN and Coast Guard
Collin Koh, senior fellow at Singapore’s S. Rajaratnam School of International Studies, highlighted the lack of coordination between the PLAN and the Coast Guard. After the collision, the Chinese destroyer DDG 164 did not stop to assist its Coast Guard vessel but instead pursued the Philippine ship. This raised questions about internal dynamics and the competency of Chinese crews, reinforcing concerns about professionalism at sea.
Traditionally, the Chinese Navy maintained a distance, supporting operations from “over the horizon” while leaving aggressive actions to the Coast Guard and maritime militia. This incident demonstrates a shift, with direct naval involvement now heightening the risk of accidents. Koh emphasised that such collisions prove that naval tensions in the South China Sea are not just dangerous for regional rivals but also hazardous for China’s own forces.
Analysts Warn of Unsafe Maritime Conduct
Jennifer Parker of the University of New South Wales observed that the accident stemmed from “aggressive behaviour and poor tactical coordination.” She warned that unsafe seamanship, when combined with China’s increasingly bold posturing, could have resulted in serious casualties.
Her assessment reflects a broader concern among defence experts: South China Sea naval tensions are sustained not just by political disputes but by unsafe practices at sea and in the air. Parker argued that the lack of large-scale casualties resulting from incidents is largely due to luck.

Wider Geopolitical Implications
The timing of the collision coincided with a significant naval deployment in the North Philippine Sea. The HMS Prince of Wales aircraft carrier joined forces with the USS Nimitz and Japan’s Kaga carrier, alongside ships from Australia, Norway, and Spain. The nine-day exercise was a clear show of allied resolve to deter China’s coercion.
Australia also conducted its largest-ever military exercise with the Philippines. Such deployments strengthen Manila’s position but also appear to provoke more aggressive Chinese responses. Graham suggested that Manila could further reinforce its stance by arranging joint patrols with US destroyers near Scarborough Shoal. This, he argued, would send an unmistakable message to Beijing.
Scarborough Shoal: The Flashpoint of Tensions
The Scarborough Shoal remains a hotspot in the dispute. Located well within the Philippines’ Exclusive Economic Zone (EEZ), it has been a symbol of South China Sea naval tensions since China seized de facto control in 2012. Beijing continues to deploy coast guard and militia fleets to block Filipino fishermen and government ships.
According to Parker, recent incidents at the shoal reflect Chinese irritation at the Philippines’ persistent presence, supported by partners like the US, UK, and India. However, Koh countered that the steady deployment of allied vessels has also prevented Beijing from escalating to armed confrontation. This external presence, he said, forces China to exercise caution while keeping its provocations below the threshold of kinetic conflict.

Transparency and International Support
A notable change in Manila’s approach is its assertive transparency strategy. The Philippine Coast Guard now routinely films encounters and releases footage online to highlight Chinese aggression. This has bolstered international support and framed Beijing as the aggressor in global opinion.
The use of rapid information campaigns demonstrates how smaller powers can harness transparency as a tool of strategic influence. By publicising China’s actions, Manila has successfully turned international attention to naval tensions in the South China Sea, reinforcing alliances and countering disinformation.
Conclusion: A Region on Edge
The collision between two Chinese vessels shows how fragile the maritime environment has become. With increasingly aggressive tactics, poor seamanship, and lack of coordination, the risk of miscalculation is rising. For the Philippines and its allies, maintaining visibility, cooperation, and transparency will be vital in preventing escalation.
South China Sea naval tensions are not simply about territorial disputes; they are about managing dangerous encounters that could trigger regional conflict. Unless China reins in its maritime forces and engages in safer practices, future collisions may prove far more costly.
