The Baton at Ayungin: Reading China’s Coercion at Second Thomas Shoal Through the First Island Chain

A reported baton attack on a Philippine sailor near Ayungin Shoal has renewed focus on China’s actions in the South China Sea. The incident may form part of Beijing’s wider plan to weaken regional resistance and improve naval access beyond the First Island Chain.

On 20 July 2026, personnel of the China Coast Guard (CCG) struck a Philippine Navy sailor on the head with a wooden baton near the BRP Sierra Madre, the warship deliberately grounded at Ayungin (Second Thomas) Shoal in 1999 to sustain Manila’s claim in the Spratly Islands. The Armed Forces of the Philippines described the assault as part of a “clear pattern of provocative and hostile behaviour“. Read in isolation, the encounter appears as one further episode of maritime harassment. Read in context, it is the tactical expression of a settled strategy.

This article argues that Beijing’s coercion in the South China Sea (SCS) is instrumental to a strategic objective: dominance over the SCS is the necessary condition for the People’s Liberation Army Navy (PLAN) to break out from the First Island Chain, and such a breakout is judged in Beijing as necessary to offset the vulnerabilities imposed on the People’s Republic of China (PRC) by the American treaty alliance system. The analysis proceeds in four parts: the pattern of coercion at Ayungin; the First Island Chain as strategic cage; the SCS as the operational seam; and the implications of the tenth anniversary of the arbitral award.

The Pattern of Coercion at Ayungin

The 20 July assault is the latest in an escalating series. In February 2023, CCG vessel 5205 directed a military-grade laser at the Philippine Coast Guard’s BRP Malapascua during a resupply mission. In........
