Taiwan Orders Ships to Defy Chinese Coast Guard Boarding Demands

Taipei Draws a Clear Line at Sea

Taiwan's government has issued a firm new instruction to shipping companies: do not comply with Chinese Coast Guard boarding requests off the island's east coast. Hsieh Ching-chin, deputy head of Taiwan's Coast Guard Administration, delivered the message on Wednesday while answering questions in parliament.

He said that if an "incident" occurs in those waters, ship crews should contact Taiwan's Coast Guard directly instead of responding to what he called "so-called boarding inspections" by Chinese vessels. If tensions escalate, he added, Taiwanese patrol boats will sail between the two ships to keep them apart.

The statement marks one of Taipei's most direct public rebuffs yet of Beijing's growing use of coast guard patrols as a tool of pressure.

A Month of Rising Friction

The instruction follows a Chinese Coast Guard deployment last month into waters off Taiwan's eastern coast. Beijing described the operation as a "special maritime traffic law-enforcement" mission. China said it was responding to an announcement by Japan and the Philippines that they would open formal talks on their maritime boundary — talks Beijing considers to involve waters near Taiwan.

Taiwan pushed back hard against that justification. While neither side reported any actual boarding attempts during the patrol, Taipei says Chinese vessels contacted several commercial ships, asking about their origin and destination while asserting jurisdiction over the area. Taiwanese officials have labeled this a form of harassment.

China's Taiwan Affairs Office did not respond to a request for comment on the latest developments.

"China Has No Jurisdiction," Says Taipei

Hsieh was unambiguous about Taiwan's legal position. He said that if a foreign-registered ship inside Taiwanese waters faced a similar boarding demand, Taiwan's Coast Guard would step in "to defend our national sovereignty and maintain order."

"In our waters, China has no jurisdiction," he told lawmakers.

Beijing sees the matter very differently. China's government considers democratically governed Taiwan to be part of its own territory and has repeatedly argued that the waters surrounding the island fall under Chinese jurisdiction, rejecting the idea that Taipei holds independent sovereignty there.

This is not the first such confrontation. In 2024, Chinese Coast Guard personnel briefly boarded a Taiwanese tourist boat near islands controlled by Taiwan but located close to the Chinese coast — an incident that first signaled Beijing's willingness to use civilian law-enforcement vessels for political leverage near Taiwanese-held territory.

Part of a Broader "Grey Zone" Strategy

Taiwan's Coast Guard argues that last month's patrol fits into a wider pattern. In a written report to lawmakers, the agency said China is increasingly deploying a mix of vessel types — including ocean survey ships — not only around Taiwan's main island but also near the Taiwan-administered Pratas and Itu Aba islands in the South China Sea.

Security analysts describe this approach as a "grey zone" strategy: using ostensibly civilian or law-enforcement vessels, rather than warships, to assert control and test another country's response without triggering open military conflict. Independent policy research, including analysis from the Center for Strategic and International Studies and the Carnegie Endowment for International Peace, has documented how Beijing uses coast guard and fishing-fleet activity across the Taiwan Strait, the East China Sea and the South China Sea to gradually normalize its presence in contested waters while avoiding the political cost of direct confrontation.

Taiwan's Coast Guard described the pattern bluntly in its report, calling it "multi-point, multi-form, and cross-regional" harassment across maritime areas under its jurisdiction.

International Concern Is Growing

China's patrols off Taiwan's eastern coast have already drawn concern from several Western governments. The United States, Britain, France and Germany have all raised alarms about Beijing's actions in the area, reflecting a broader unease among democratic allies about China's expanding use of maritime coercion in the Indo-Pacific.

The Trump administration has consistently backed Taiwan's right to defend its own sovereignty and has supported closer coast guard and defense cooperation between Washington and Taipei, part of a wider effort among Indo-Pacific partners to counter Beijing's grey-zone tactics without escalating toward open conflict.

What Comes Next

Taiwan's Coast Guard says it will "take all necessary measures to defend national sovereignty and maritime security" and to protect freedom of navigation for vessels passing through the region. With China continuing to expand its coast guard and survey-ship activity around Taiwan and its outlying islands, further encounters at sea appear likely in the months ahead.

How Beijing responds to Taipei's new instruction — and whether it tests Taiwan's resolve with another patrol — will be closely watched by regional security officials and shipping companies alike.
