China’s campaign of pressure against Taiwan took another step forward this weekend when four Chinese government vessels entered restricted waters near Taiwan’s southern coast. This time, however, Taiwan did not simply monitor the intrusion. It responded forcefully, dispatching seven coast guard vessels and ultimately driving the Chinese ships out of the area. The incident highlights both the growing frequency of Chinese maritime harassment and the increasingly assertive response from Taiwan.

Chinese Ships Enter Restricted Waters

According to Taiwan’s Coast Guard Administration, four Chinese government ships, including three Chinese coast guard vessels, sailed into Taiwan’s restricted waters approximately 30 nautical miles southwest of the island’s southern tip on June 7. Chinese state media described the operation as a “special maritime traffic law-enforcement operation” conducted in waters east of Taiwan.

Taiwan immediately responded by sending seven coast guard vessels to intercept the Chinese formation. The two sides exchanged radio warnings as Taiwanese ships moved to challenge the intrusion. By late afternoon, Taiwan announced that all four Chinese government vessels had been expelled from the restricted area.

The radio exchange illustrated the sharply different views held by Beijing and Taipei.

A Chinese officer declared: “These are waters under Chinese jurisdiction. Our maritime law-enforcement formation is carrying out a special traffic law-enforcement mission in the waters of the Taiwan Strait. Do not interfere with our official duties.”

A Taiwanese officer rejected the claim outright, responding that China possesses no sovereign rights in the waters east of Taiwan. The Taiwanese officer further warned, “If conflict occurs, your side will face sanctions from the world. Only maritime stability can ensure your country’s development.”

Why China Claims the Right to Do This

The confrontation stems from Beijing’s longstanding position that Taiwan is not an independent nation but rather a province of China. The Communist government in Beijing continues to insist that all waters surrounding Taiwan ultimately fall under Chinese authority.

China’s latest operation appears connected to growing tensions over maritime boundaries in the region. Beijing has expressed anger over plans by Japan and the Philippines to begin formal discussions regarding maritime boundary delimitation. Chinese officials view those discussions as involving waters near Taiwan, which China claims as its own territory.

Taiwan rejects those claims entirely. Taiwan operates as a self-governing democracy with its own military, government, legal system, and elections. Beijing has never ruled Taiwan, yet it continues to maintain that reunification remains an official objective and has never renounced the use of force to achieve it.

A Pattern of Escalating Harassment

While this incident attracted attention because Chinese vessels entered restricted Taiwanese waters and had to be physically driven away, it is only the latest example in a much broader campaign of maritime and military pressure.

Taiwan has reported increased Chinese coast guard activity during the past several weeks, including confrontations around the Taiwan-controlled Pratas Islands in the northern South China Sea. Chinese military aircraft and naval vessels already operate around Taiwan almost daily.

The pattern has become increasingly aggressive over the past several years.

In July 2023, China deployed 37 military aircraft and seven naval vessels around Taiwan during a major demonstration of force. According to reports, 22 of those aircraft crossed the median line of the Taiwan Strait, an unofficial boundary that had long helped reduce tensions between the two sides. The deployment included J-10 and J-16 fighter aircraft as well as H-6 bombers.

That operation occurred shortly before Taiwan’s annual Han Kuang military exercises and was widely viewed as an attempt to intimidate the island and remind Taiwanese leaders that China possesses overwhelming military power.

The 90-Ship Show of Force

Perhaps the most dramatic example of China’s maritime pressure came in December 2024.

Taiwan’s Defense Ministry reported that approximately 90 Chinese vessels were operating around Taiwan, southern Japan, and nearby waters. Taiwanese officials stated that roughly two-thirds of those vessels belonged to China’s navy. The scale of the deployment was described as unprecedented.

At the same time, China established multiple restricted airspace zones off its coast and conducted activities extending across what military planners call the “first island chain,” stretching from Japan through Taiwan and the Philippines.

Taiwan characterized the operation as part of China’s growing “gray zone” campaign. These are activities designed to pressure an opponent without crossing the threshold into open warfare. Instead of launching an invasion, Beijing gradually increases military and coast guard activity in hopes of normalizing its presence and wearing down Taiwan’s defenses.

Pressure After Taiwan’s Elections

China has also repeatedly used ships and aircraft to express dissatisfaction with Taiwan’s democratic elections.

Following the election of President Lai Ching-te in January 2024, China dispatched warships toward Taiwan and increased military activity around the island. Beijing viewed Lai’s victory as a setback because he has historically been associated with support for Taiwanese sovereignty. Chinese officials quickly reiterated that Taiwan remained part of China regardless of election outcomes.

The deployment fit a familiar pattern. Whenever Taiwan strengthens ties with the United States, conducts military exercises, or elects leaders Beijing dislikes, China often responds with naval deployments, aircraft incursions, military drills, or economic pressure.

A New Stage in the Confrontation

What makes this week’s incident different is that Chinese government vessels moved directly into restricted Taiwanese waters and were confronted by a larger Taiwanese coast guard force. Rather than merely observing the intrusion, Taiwan took active steps to force the vessels out.

Taiwan National Security Council Secretary-General Joseph Wu summarized the island’s frustration with Beijing’s tactics, writing on social media: “The PRC is nothing but a big fat bully.”

Whether one agrees with that characterization or not, the broader trend is difficult to ignore. Chinese military aircraft, coast guard ships, naval vessels, and surveillance operations have steadily increased around Taiwan in recent years. Each operation pushes a little further than the last.

The concern for many observers is not necessarily any single incident. It is the cumulative effect. China appears to be testing limits, normalizing its presence, and gradually increasing pressure on Taiwan one step at a time. This week’s confrontation showed that Taiwan is increasingly willing to push back. It also demonstrated that the maritime struggle between Beijing and Taipei continues to intensify, raising the risk that one future encounter could become far more dangerous than a radio exchange and a forced withdrawal.
