A blockade rehearsed in plain sight

China’s pressure around Taiwan is becoming more coordinated, more geographically ambitious and harder to dismiss as routine intimidation. Taiwan’s Coast Guard Administration says Beijing is combining maritime militia vessels, coast guard ships and military assets in operations around Taiwan and the western Pacific—activity that officials describe as preparation for a possible blockade.[3]

The distinction matters. A blockade would be an act of war, but the preparations can take place below that threshold. Fishing boats, law-enforcement vessels and civilian-looking ships can test routes, observe reactions and create legal confusion without immediately inviting a military confrontation. China’s approach is designed to make coercion appear administrative rather than belligerent.

That ambiguity is the point. Beijing can claim that its vessels are conducting law-enforcement or maritime activity while imposing costs on Taiwan and challenging the operating space of neighbouring countries. The result is a gradual erosion of normality: Chinese state-linked vessels appear more frequently, patrol farther from the mainland and force others to decide whether each encounter deserves escalation.

Japan and the Philippines are part of the pressure map

The operation is not confined to Taiwan’s immediate waters. Taiwan’s coast guard has warned that Chinese activity is also placing pressure on Japan and the Philippines, both of which occupy critical positions along the first island chain.[3]

An incident near Penghu illustrated the wider reach of this strategy. Taiwan said five Chinese coast guard ships followed eight Japan Coast Guard vessels as the Japanese ships sought shelter from Typhoon Champi.[1] Taiwanese officials argued that the episode risked creating the false impression that the Taiwan Strait is an internal Chinese waterway rather than an international passage.[8]

The timing made the manoeuvre especially revealing. A typhoon should have been a moment for practical maritime safety, not strategic theatre. Yet the shadowing of Japanese vessels demonstrated how Beijing can use an ordinary operational setting to advance an extraordinary political claim.

Such encounters also test allied coordination. Japan must protect its ships without giving China an excuse to portray Tokyo as provocative. Taiwan must monitor the activity while avoiding unnecessary escalation. The Philippines and other regional states must calculate whether China’s maritime presence near Taiwan will eventually be replicated closer to their own shores.

Influence operations are becoming more selective

The pressure is not only at sea. Taiwan’s National Security Bureau says Beijing is targeting particular groups and audiences ahead of Taiwan’s elections, rather than relying solely on broad propaganda.[7]

That shift suggests a more sophisticated model of interference. Targeted pressure can include financial inducements, subsidised travel, political outreach and efforts to mobilise voters or influence selected candidates. A U.S. think-tank report has also cited alleged pressure on relatives of prominent Taiwanese figures whom Beijing labels “separatists.”[10]

The objective is not necessarily to persuade every Taiwanese voter that China is right. It may be enough to intimidate activists, divide political parties, discourage participation or make democratic institutions appear vulnerable to external manipulation.

This is coercion adapted to the information age: personalised, deniable and calibrated. It exploits family ties, economic dependence and social divisions while allowing Beijing to deny responsibility.

Public opinion is hardening

The campaign may be producing the opposite of its intended political effect. A Taiwan Mainland Affairs Council survey found that 52.3 per cent of respondents believed the Chinese Communist Party was undermining cross-strait peace, up from 47.4 per cent in May.[5]

That nearly five-point increase matters because it reflects how sustained pressure is shaping public judgement. Taiwanese citizens are not viewing coast guard patrols, maritime militia operations and election interference as separate incidents. They are increasingly seeing them as parts of a single strategy.

Beijing’s challenge is that coercion can strengthen the very identity and resistance it seeks to weaken. Every suspicious maritime encounter or targeted political operation gives Taiwan’s public another reason to distrust promises of peaceful integration.

Deterrence must match the method of coercion

Warnings from American and Taiwanese officials point to an uncomfortable conclusion: deterrence remains incomplete. The chair of the U.S.-China Economic and Security Review Commission has argued that Taiwan and the United States still lack the “hellscape” capabilities needed to complicate a Chinese invasion.[10]

Former U.S. defence official Randall Schriver has likewise described Chinese coast guard patrols east of Taiwan as an extension of legal, political and information warfare.[10] That assessment should change how deterrence is measured. It is not enough to prepare for missiles crossing the Taiwan Strait. Taiwan and its partners must also be ready for quarantine tactics, port disruption, cyber operations, disinformation and swarms of ostensibly civilian vessels.

China is exploiting the space between peace and war. The answer cannot be panic, but neither can it be complacency. Taiwan needs resilient maritime surveillance, rapid attribution, protected communications and a clear plan for responding to coercive operations without surrendering the initiative.

The wider region, meanwhile, must recognise that every “grey-zone” incident is a strategic signal. Beijing is learning how far it can go before others act. If the response remains fragmented, China’s incremental pressure will become established practice—and established practice can become the foundation of a crisis.
