China Quietly Mobilizes Over 100 Warships And Patrol Vessels. Is Beijing Rehearsing a Taiwan Blockade?

China deployed more than 100 naval and coast guard vessels across the western Pacific and waters surrounding Taiwan in an unusually large military operation that went unannounced by Beijing, raising questions about whether its forces were rehearsing a blockade of the island and efforts to prevent American military intervention.

The exercises, conducted in early November, involved simulated attacks on opposing military forces and cities, including those in Taiwan, according to a senior Taiwanese security official who spoke to Reuters. The deployment exceeded the scale of China's last formally announced exercises targeting Taiwan, known as Justice Mission 2025.

What made the operation particularly unusual was Beijing's silence. Despite mobilizing forces from three military theater commands and deploying its Liaoning aircraft carrier group, China did not publicly announce a major exercise or give it an official name.

A Taiwanese security official described the operation as "silent intimidation," an apparent attempt to apply military pressure without provoking the diplomatic response that typically accompanies large-scale drills around the island.

The movements come days before U.S. President Donald Trump and Chinese President Xi Jinping are expected to meet at the Asia-Pacific Economic Cooperation summit in Shenzhen, with Taiwan once again emerging as a central issue in relations between Washington and Beijing.

The scale and geographic reach of the operation have also drawn attention from military analysts, particularly because Chinese vessels were operating well beyond the waters immediately surrounding Taiwan.

The South China Morning Post reported that the deployments had raised questions about whether the People's Liberation Army was practicing operations to keep U.S. and allied forces from intervening in a potential Taiwan conflict.

Unlike an invasion, which would involve sending troops and equipment onto the island, a blockade could attempt to isolate Taiwan by restricting access to its ports and surrounding waters.

Such an operation would present a different challenge for Washington, which maintains unofficial relations with Taipei and supplies weapons for its defense.

Analysts cited by the South China Morning Post pointed to the positioning of Chinese naval forces across the western Pacific and South China Sea as a possible indication that Beijing was rehearsing ways to prevent outside forces from reaching Taiwan.

An assessment by the Institute for the Study of War similarly suggested that Chinese forces could be conducting a major exercise simulating Taiwan's isolation, with warships positioned to complicate potential intervention by foreign militaries.

The assessments do not establish that China has decided to impose a blockade or launch military action against Taiwan.

However, the involvement of China's Eastern, Northern and Southern Theater Commands marks a significant departure from exercises focused primarily on the Taiwan Strait.

Taiwanese officials told Reuters that the joint deployment suggested Beijing was developing the ability to coordinate its regional fleets across a much larger operating area.

Taiwanese Defense Minister Wellington Koo said earlier this week that Chinese forces were conducting what he described as "area denial" exercises involving the Liaoning aircraft carrier and other naval formations.

Area denial operations are intended to prevent an opposing military from entering or operating freely within a particular region. In the western Pacific, such tactics could affect the ability of American and allied forces to approach Taiwan during a military confrontation.

A Chinese submarine also launched an intercontinental ballistic missile from the Yellow Sea into mainland China during the broader exercise period, according to the senior Taiwanese security official cited by Reuters.

The missile activity was not independently confirmed in the reporting and should not be taken as evidence that a nuclear attack was being rehearsed.

Beijing has not publicly acknowledged the broader operation as a coordinated exercise. China's Defense Ministry did not respond to Reuters' request for comment, while Chinese officials have described the Liaoning carrier group's activities as routine training not directed at any particular country.

The operation coincided with renewed remarks by Xi on Taiwan's political future. In a speech Thursday commemorating revolutionary leader Sun Yat-sen, Xi called for peaceful reunification with Taiwan, reiterating Beijing's longstanding position that the island is part of China.

Beijing has never renounced the use of force to bring Taiwan under its control. Taiwan's government rejects China's sovereignty claims and maintains that its future must be decided by its people.

The latest naval movements have not gone unnoticed in Taipei. Taiwan's National Security Council Secretary-General Joseph Wu said Thursday that Chinese naval formations from all three theater commands, along with the Liaoning carrier strike group, remained active in waters east of the Philippines.

Although the number of vessels had declined from more than 100 earlier this month to approximately 70 by Friday, Chinese air force activity near Taiwan remained elevated, according to Taiwanese security officials.

Taiwan's Defense Ministry reported detecting 30 Chinese military aircraft sorties, eight naval vessels and three other official vessels operating around the island during the 24 hours ending at 6 a.m. Friday.

Twenty-three of those aircraft sorties crossed the Taiwan Strait's median line or entered Taiwan's northern, central, southwestern and eastern air defense identification zone.

Those daily figures cover a smaller area immediately surrounding Taiwan and are separate from the wider western Pacific deployment.

The exercises also come as the United States strengthens military cooperation with regional partners, including Japan, Australia and the Philippines.

Washington and its allies have expanded joint military exercises and coordination in recent years, partly in response to China's growing naval presence and territorial claims in the region.

A separate Reuters analysis published Friday examined how Beijing's area denial capabilities could complicate any American effort to intervene in a Taiwan conflict. It also noted that regional governments are strengthening defense cooperation in response to China's military activities.

Taiwan's security has broader economic implications because the island is a major producer of advanced semiconductors used in smartphones, data centers and artificial intelligence systems.

A disruption to shipping or semiconductor manufacturing around Taiwan could affect businesses far beyond East Asia, making developments in the Taiwan Strait a concern for governments and multinational companies.

For now, neither Beijing nor Taipei has reported an imminent military confrontation.
