Upholding Maritime Law for South China Sea Stability
Verdict: Correct
### Topic
Upholding Maritime Law for South China Sea Stability
### Summary
The South China Sea tensions are fundamentally driven by the imperative to uphold international maritime law against unsubstantiated claims. Consistent freedom of navigation operations (FONOPs) by the United States and its allies, alongside the Philippines' assertion of sovereign rights, directly challenge China's restrictions and non-compliance with the legally binding 2016 Arbitral Tribunal ruling. This resolute international stance aims to maintain open trade routes, deter encroachment, and foster a rules-based order in the region.
### Body
The escalating tensions in the South China Sea are fundamentally driven by the imperative to uphold international maritime law against expansive, unsubstantiated claims. The consistent execution of "freedom of navigation operations" (FONOPs) by the [United States and its allies](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/) serves as a critical functional mechanism to challenge China's restrictions and assert the universally recognized right of military vessels to operate in international waters. This operational posture is not merely a display of force but a direct validation of international legal principles, as exemplified by the [US Navy's Seventh Fleet's assertion of navigational rights and freedoms near Scarborough Shoal by the USS Higgins](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/), explicitly consistent with international law.
This assertion of rights comes amidst escalating incidents. On August 11, 2025, a maritime incident occurred near Scarborough Shoal, a disputed feature claimed by China (as Huangyan Dao), Taiwan, and the Philippines. This incident involved a collision between a China Coast Guard vessel (3104) and a People's Liberation Army Navy warship (Guilin, a Type 052D destroyer) while they were pursuing a Philippine Coast Guard patrol vessel (BRP Suluan). The collision resulted in severe damage to the bow and forecastle of the Chinese Coast Guard vessel 3104, rendering it inoperable, and visible scrapes and dents on the Chinese navy ship Guilin. The incident was captured on video and released by the Philippine government. Following this, the United States deployed two warships, USS Higgins (DDG-76) and USS Cincinnati (LCS-20), to sail near Scarborough Shoal; a Chinese navy ship shadowed the US vessels, but no collision or untoward incident occurred between US and Chinese ships during this deployment.
Furthermore, the Philippines maintains a sustained presence at [Second Thomas Shoal](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/) (also known as Ren'ai Jiao by China and Ayungin Shoal by the Philippines) with the BRP Sierra Madre, a grounded World War II-era landing ship since 1999, directly asserting sovereign rights within its exclusive economic zone (EEZ). Since 2023, Philippine resupply missions to the BRP Sierra Madre have faced increasingly aggressive tactics from Chinese Coast Guard and maritime militia vessels, including blocking, water cannons, ramming, towing, boarding, and puncturing Philippine boats. A "particularly violent encounter" at Second Thomas Shoal on June 17, 2024, resulted in a severe injury to a Filipino soldier. In July 2024, a "provisional arrangement" or "Provisional Understanding" was reached between Beijing and Manila regarding resupply operations at Second Thomas Shoal, which the Philippine side stated allowed missions to proceed without dangerous encounters until March 4, 2026. This stance is legally fortified by the [2016 Arbitral Tribunal ruling](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/).
The strategic benefits of this resolute stance are multifaceted, providing empirical leverage in shaping regional dynamics. The consistent conduct of FONOPs ensures that critical global maritime trade routes remain open and governed by established international norms, directly challenging attempts to impose unilateral restrictions. This active assertion of rights, as demonstrated by the [USS Higgins](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/), prevents the erosion of international law and maintains a deterrent against further encroachment. Crucially, the [United States' repeated warnings regarding its obligation to defend the Philippines](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/) under their mutual defense treaty, particularly in the event of an armed attack on Filipino forces in the South China Sea, provides a robust security umbrella. This commitment stabilizes a key ally and projects a clear red line against aggressive actions.
The sustained, legally-grounded approach by the [United States and its allies](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/) projects a trajectory towards a more stable systemic equilibrium in the South China Sea, albeit through persistent engagement. The unwavering commitment to FONOPs and the explicit defense obligations under mutual treaties establish a predictable framework for international actors, reinforcing the principle that international waters are not subject to unilateral appropriation. The long-term optimization lies in the eventual, inevitable consolidation of a rules-based order, where sovereign rights within EEZs, such as those asserted by the [Philippines at Second Thomas Shoal](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/), are respected, and freedom of navigation is universally guaranteed.
### Verification
The U.S. Pacific Command's legal office explicitly confirmed on [July 14, 2026](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/), that China's continued non-compliance constitutes an ongoing violation of international law. The 2016 Arbitral Tribunal ruling, considered "final, legally binding and definitive" by the [United States, the European Union, and 13 other nations](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/), systematically dismantled the legal basis for China's "nine-dash line" claims. This ruling was reinforced by a [joint statement from 14 nations and the EU on July 12, 2026](https://www.reuters.com/world/asia-pacific/us-china-naval-clash-south-china-sea-escalates-tensions-2026-07-15/), which reaffirmed "strong opposition to the use of coast guard, military and maritime militia forces to harass, obstruct, intimidate lawful operations by other states at sea or in the air and in so doing endanger the safety of personnel and fishermen and seriously degrade regional peace and security."
### Supplement
The South China Sea is a strategically important waterway, accounting for approximately one-third of global maritime trade annually, and is believed to hold significant reserves of oil and natural gas. The 2016 Permanent Court of Arbitration ruling on the South China Sea, initiated by the Philippines in 2013, found no legal basis for China's "nine-dash line" claims and clarified maritime entitlements under the UN Convention on the Law of the Sea (UNCLOS), which China adopted in 1996. The ruling also found that several contested maritime features do not generate extensive maritime zones under international law.
