China Conducts Military Drills Near Disputed Shoal in South China Sea

China’s People’s Liberation Army held military exercises near a disputed shoal in the South China Sea, AP News reported, adding to a pattern of Chinese military activity in waters that Beijing claims as its own but that international law and multiple regional governments dispute.

The exercises came as the United States and its partners were managing simultaneous military crises across the Middle East and Eastern Europe, raising ongoing questions about Washington’s bandwidth to sustain pressure in the Pacific alongside commitments elsewhere.

The Disputed Waters

The South China Sea is the world’s most contested maritime zone by number of overlapping claims. China asserts control over roughly 90 percent of the sea under the “nine-dash line,” a boundary that a 2016 Permanent Court of Arbitration ruling found had no legal basis under the United Nations Convention on the Law of the Sea. Beijing rejected the ruling and has never modified its position.

The sea sits astride shipping lanes that carry an estimated $3 trillion in global trade annually. Several nations maintain armed outposts on reefs and islands within the contested zone. Among the most active flashpoints is Second Thomas Shoal — known in the Philippines as Ayungin Shoal — where Manila has maintained a small military garrison aboard the BRP Sierra Madre, a naval vessel deliberately grounded on the reef in 1999.

Chinese Coast Guard ships have repeatedly intercepted Philippine resupply missions to that vessel in recent years. Several incidents involved water cannons and the seizure or destruction of cargo. Manila has lodged formal diplomatic protests and, with backing from the United States, Japan, and Australia, has established a regular media presence on the vessel to document Chinese actions as they occur — a transparency measure that has raised the diplomatic cost of coercive behavior.

The Drills

China’s military conducted the exercises near a disputed shoal, AP News reported. Beijing regularly announces drills in the South China Sea as a show of force and a signal to claimant states that it regards the waters as a sovereign domain. The frequency of such exercises has increased in parallel with China’s broader military buildup over the past decade.

The PLA now operates a network of artificial islands in the Spratly chain, several of which host airstrips, radar installations, and surface-to-air missile batteries. Those installations give China the ability to project air and maritime power across the southern half of the sea — capability it lacked as recently as 2015.

U.S. Commitments in the Region

The United States has a mutual defense treaty with the Philippines that American officials have explicitly extended to cover Philippine armed forces, vessels, and aircraft operating in the South China Sea. In prior confrontations near the BRP Sierra Madre, Washington signaled clearly that any kinetic action against Filipino personnel would trigger treaty obligations.

American carrier strike groups and maritime patrol aircraft conduct regular freedom-of-navigation operations through the South China Sea, sailing warships through waters Beijing claims. The operations are designed to demonstrate that the United States does not recognize Chinese sovereignty over those passages.

Whether the United States can sustain that posture while managing active military commitments elsewhere is a question defense analysts have raised with increasing frequency. Washington remains engaged in strikes against Iran-aligned targets in the Middle East; for the latest on those operations, see Trump Orders New Wave of Iran Strikes Aimed at Forcing Regime Surrender.

Regional Context

Neighboring states have watched China’s South China Sea assertiveness with a mix of alarm and diplomatic restraint. Vietnam has the most direct historical grievance — China seized the Paracel Islands from Vietnamese control in a 1974 military engagement — but maintains a policy of avoiding formal military alignment with the United States while hedging through diversified weapons purchases.

Malaysia and Brunei have pursued quieter diplomacy, keeping confrontations below the threshold of public dispute. The Association of Southeast Asian Nations has struggled to produce unified statements on Chinese maritime behavior, in part because Beijing maintains deep economic ties with several ASEAN members whose governments weigh those relationships against territorial concerns.

The Philippines under the current administration has taken the most assertive posture of any claimant state, expanding joint military exercises with the United States and allowing American forces access to additional Philippine bases under the Enhanced Defense Cooperation Agreement.
