A month ago, China's coast guard escalated beyond shoving resupply convoys—it blasted water cannons at small Philippine fishing boats near Sabina (Escoda) Shoal, damaged two vessels, and left three fishermen injured, while Chinese craft allegedly cut anchor lines and boxed out rescuers. Manila filed a diplomatic protest calling the actions "dangerous" and "inhumane." But the pressure hasn't stopped: in early January 2026, Chinese naval and coast guard vessels appeared during a search-and-rescue operation off Zambales—closer to the Philippine mainland than the usual reef flashpoints.

Sabina has become a test of who gets to police the Philippines' own waters. If China can normalize "control measures" here, it tightens a choke point near other Philippine-held features—and pushes Manila toward tougher escorts, louder allies, and a hair-trigger definition of what counts as an attack. The Philippines now chairs ASEAN for 2026 and is pushing to finalize a South China Sea Code of Conduct by July, even as analysts doubt Beijing will accept binding constraints while it holds tactical momentum at sea.

Scenarios
1
Manila Starts Escorting Fishermen Like Resupply Convoys
If civilian targeting persists, Manila is likely to treat fishing activity as protected presence—more PCG ships, tighter formations, quicker medical response assets, and nonstop documentation. That reduces China’s freedom to intimidate quietly, but it also increases ship density in tight waters, making collisions and escalation-by-accident more probable.
2
China Builds a Soft Blockade Around Sabina—And Tests How Long the Philippines Can Hold
Discussed by: Analysts quoted by The Guardian (SeaLight’s Ray Powell; CSIS AMTI’s Harrison Prétat); reporting on 2024 vessel surges
A sustained Chinese cordon—constant rotations of CCG and militia craft, harassment of fuel and provisions, and aggressive maneuvering—would aim to exhaust Philippine ships and crews without firing a shot. The trigger would be Manila increasing presence again at Sabina or linking it operationally to Second Thomas missions. The endgame is simple: make Philippine presence episodic, then call that “proof” of Chinese jurisdiction.

A Quiet “Rules of the Road” Deal Emerges for Sabina
Discussed by: Diplomacy parallels drawn from the 2024 Second Thomas ‘provisional arrangement’ coverage (Reuters)
A backchannel understanding—distance buffers, no cutting across bows, limits on water cannon use—could appear if both sides fear a fatal incident and want to stabilize the theater. It would likely be informal, deniable, and narrow, because neither wants to concede sovereignty. It requires Beijing to believe restraint serves its interests more than pressure does, which is a high bar.
4
A Death at Sea Triggers a Treaty Crisis and Emergency Joint Operations
Discussed by: Philippine presidential warnings quoted by The Guardian; repeated U.S. statements tying the treaty to maritime forces in disputed waters
A fatality—especially if Manila frames it as a deliberate act—could force rapid escalation: emergency allied statements, expanded joint patrols, and potentially U.S. operational support around Philippine missions. Beijing would likely respond with more ships, not fewer, betting that fear of war limits U.S. and Philippine moves. This is the nightmare scenario: everyone insists they’re de-escalating while accelerating.
5
The Code of Conduct Becomes a Showdown Over What 'Binding' Actually Means
Discussed by: Analysts at Chatham House, CSIS, and The Diplomat covering 2026 ASEAN chairmanship; Philippine Foreign Secretary Theresa Lazaro statements
Manila is pushing for a legally binding Code of Conduct by July 2026, proposing weekly negotiation meetings to meet ASEAN-China's self-imposed deadline. But 'binding' is where consensus collapses: the Philippines wants enforceable rules with dispute mechanisms, while China historically resists anything that limits its operational freedom or subjects sovereignty claims to external review. If negotiations stall publicly during the Philippine chairmanship, it would expose ASEAN's limits and potentially push Manila to rely even more heavily on bilateral defense partnerships with the US, Japan, and Australia—making the diplomatic track look like theater while the military track hardens.
Historical Context
Scarborough Shoal Standoff
2012
What Happened
A confrontation over arrests and access spiraled into a prolonged face-off. After a U.S.-brokered pullback, China effectively held the ground—controlling access and normalizing its presence.
Outcome
Short Term
Philippine access became harder and more conditional.
Long Term
It became Manila’s cautionary tale: a ‘temporary’ standoff can become permanent loss.
Why It's Relevant Today
Sabina scares Manila because it looks like the same slow squeeze, just closer to other critical features.
Haiyang Shiyou 981 Oil Rig Crisis (China–Vietnam)
2014-05 to 2014-07
What Happened
China moved a major oil rig into disputed waters and guarded it with a large flotilla. Vietnam’s ships challenged it; collisions and water cannon use became part of the contest.
Outcome
Short Term
China withdrew the rig after months, but tensions and distrust deepened.
Long Term
It showed how ‘non-war’ tools—ramming, spraying, swarming—can still reshape reality.
Why It's Relevant Today
It’s a blueprint for how China can press claims hard without crossing into open combat.
BRP Sierra Madre Grounding at Second Thomas Shoal
1999 to present
What Happened
The Philippines deliberately grounded an old naval ship to anchor its claim. China couldn’t remove it without escalating, so it tried to strangle it—blockades, water cannons, and interference with resupply.
Outcome
Short Term
A rusting ship became a live military outpost and a recurring trigger for crises.
Long Term
It turned logistics into strategy: whoever controls access controls the outpost.
Why It's Relevant Today
Sabina matters partly because it can become a staging ground—or choke point—for Second Thomas.
