In 2026, Two Chinese Coast Guard Ships Patrol the East Coast of Taiwan, PLA's Gray Zone Pressure Extends to the Pacific Side

On November 1, Taiwan reported that two Chinese Coast Guard ships were operating in the eastern waters of Taiwan, one of which continuously broadcasted so-called law enforcement information, while the other approached the Dongsha Islands. With only two ships involved, the news impact is certainly not comparable to that of dozens of military aircraft or aircraft carrier formations, but this is precisely where such actions are worth analyzing: they do not rely on one-off large-scale displays but instead use low-cost, repeatable maritime presence to test the opponent's reactions.

What Are the Two Coast Guard Ships Testing?

According to publicly available information from Taiwan's Coast Guard and related reports from Reuters, this operation did not announce a blockade and was not accompanied by missile launches or large-scale naval exercises. The Taiwanese side stated that the Chinese vessels broadcasted under an unrecognized jurisdiction and caused disruptions to shipping; the Chinese narrative publicly framed the action within the context of "performing duties according to the law." While the descriptions from both sides differ, a confirmed fact is that the Chinese Coast Guard is incorporating the eastern side of Taiwan into a more sustained patrol radius.

The Dongsha Islands are over 400 kilometers from Taiwan's main island, and this year, Taiwan has repeatedly reported driving away or monitoring Chinese Coast Guard ships. This figure does not equate to a blockade being established, but it indicates that the eastern shipping lanes are becoming areas of repeated contact between both sides. The mission of the Coast Guard ships is not to sink targets but to approach, shout, escort, delay, and record, breaking down a military crisis into many seemingly limited law enforcement events.

Why Choose the East Coast of Taiwan?

The west coast of Taiwan faces the mainland, making it the most predictable direction of pressure; the east coast faces the Philippine Sea, which relates to wartime external supplies, intelligence support, and evacuation routes. If the PLA Navy intends to implement a high-intensity blockade, it would require ships, submarines, air forces, and long-range firepower; the Chinese Coast Guard can first enter this maritime area with a lower risk of escalation, observing the speed of Taiwan's Coast Guard deployments, radio procedures, and whether commercial vessels change their routes.

This is the engineering aspect of gray zone operations. Each patrol accumulates data on shipping lanes, tides, communications, and opponent reactions, and also familiarizes crew members with the maritime environment on the eastern side of Taiwan. In simple terms, the Coast Guard ships may not be completing a blockade today but are calibrating parameters for some more complex maritime control scheme in the future.

Coast Guard Cannot Replace the Navy

It is necessary to avoid exaggerating the two Coast Guard ships as a "successful blockade exercise." The sensors, protection, and firepower configurations of Chinese Coast Guard ships cannot be equated with those of the Type 055 destroyers or aircraft carrier formations; in cases of clear resistance from the opponent, intervention from allies, or escalation of air and naval combat, the Coast Guard forces must rely on the PLA for cover. Its advantage lies in the ambiguity brought by its legal status and numbers, rather than direct combat capability.

The author believes that the real change is that the Coast Guard has become a forward node in the PLA's pressure system across the Taiwan Strait. Military aircraft are responsible for creating aerial pressure, the navy is responsible for high-end deterrence, and the Coast Guard extends contact into commercial shipping and daily law enforcement. With these three elements combined, what Taiwan needs to respond to is no longer a clearly announced exercise but a continuously changing reaction chain.

Next Steps: Focus on Frequency Rather Than Tonnage

In the future, three indicators should be closely monitored: whether patrols expand from eastern Taiwan to the Dongsha Islands and the Bashi Channel, whether there are synchronized activities between the Coast Guard and maritime militia or naval vessels, and whether Taiwanese and foreign commercial ships begin to adjust their routes to avoid conflict. If there are only sporadic patrols, their political value is higher than their military value; if a fixed cycle and multi-point coordination are formed, the logistical security costs on the eastern side of Taiwan will substantially increase.

Reference sources include public reports from Taiwan's Coast Guard, publicly available information from the Chinese Coast Guard, related reports from Reuters, and publicly available satellite and shipping data on Taiwan's maritime situation. The most pressing question now is not whether two ships can block a shipping lane, but whether Beijing can turn this low-intensity presence into a set of normal mechanisms that can continuously change shipping expectations without the need for temporary mobilization.
