Taiwan stations 100-tonne patrol boat at Pratas as China increases South China Sea patrols

Overview

Updated 1 hour ago

A 100-tonne patrol boat is now permanently based at Pratas Island, a Taiwan-controlled atoll in the South China Sea more than 400 kilometers from Taiwan's main island. Taiwan's Coast Guard Administration announced the move on September 23 as part of a "comprehensive" upgrade of patrol capacity around the disputed outpost.

The upgrade responds to a surge in China Coast Guard patrols near Pratas, which rose from occasional transits in 2023 to 60 observed activity days in 2025. Taiwan previously kept only small coastal boats at the island and relied on periodic visits by larger ships, leaving it stretched when Chinese vessels appeared.

Why it matters

Pratas tests whether Taiwan can hold its outlying islands as China turns gray-zone patrols into routine presence.

Scenarios

CCG patrols intensify but no armed clash erupts

Likely Resolves by Q1 2027

Discussed by: CSIS's Asia Maritime Transparency Initiative and Taiwan's Coast Guard Administration

Chinese coast guard and fisheries vessels keep pressing toward Pratas, with 2026 activity on track to exceed 2025's 60 patrol days. Taiwan's 100-tonne boat and rotating larger vessels respond, expelling fishing boats and shadowing Chinese ships. The standoff persists without direct military force, as both sides keep escalation below the threshold of an armed clash.

China attempts to blockade or seize Pratas

Unlikely Resolves by Q2 2027

Discussed by: ORF analysts and security experts quoted by Reuters

China escalates its gray-zone campaign by tightening a de facto blockade around Pratas, cutting supply to the island, or attempting an amphibious landing. Taiwan's navy would likely respond with convoy escorts, risking direct confrontation. Security analysts note Pratas's distance from Taiwan and proximity to mainland China make it one of the most vulnerable Taiwan-controlled outposts.

Vessel-level clash near Pratas

Possible Resolves by Q2 2027

Discussed by: Taiwan's Coast Guard Administration warnings and AMTI patrol tracking

Taiwanese and Chinese vessels collide or exchange fire during an expulsion or shadowing operation. Taiwan has already expelled Chinese fishing boats this year, and the CGA says Chinese ships deliberately maneuver at the edge of restricted waters to tie up Taiwan's enforcement resources. A miscalculation or aggressive maneuver could escalate to damage or casualties.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

February 1995

Mischief Reef (1995)

In February 1995, the Philippines discovered China had built four concrete structures on Mischief Reef, a submerged atoll in the Spratly Islands. Beijing called them shelters for fishermen; Manila called it occupation.

Then

China rejected Philippine protests and kept the structures, eventually expanding them into a military outpost with an airstrip.

Now

Mischief Reef became the template for China's South China Sea island building, showing that a gradual foothold on a distant outpost is hard to reverse without direct confrontation.

Why this matters now

Like Pratas, Mischief Reef sits far from the claimant's main territory. China's incremental approach there may be repeating near Taiwan.

April-June 2012

Scarborough Shoal (2012)

In April 2012, Philippine warships tried to detain Chinese fishermen at Scarborough Shoal. Chinese vessels blocked them, triggering a two-month standoff. China agreed to a withdrawal deal but its ships never left.

Then

China gained de facto control of the shoal and has maintained a coast guard presence since, effectively excluding Philippine fishermen.

Now

Scarborough showed Beijing's preference for using law-enforcement vessels rather than the navy to achieve enduring control of contested features.

Why this matters now

China's coast guard patrols near Pratas follow the same logic: build routine presence with paramilitary ships, avoid a decisive fight, and let control congeal.
