On February 29, 12 Chinese warplanes crossed the Taiwan Strait median line, a de facto boundary that Beijing does not recognize. Taiwan responded by scrambling fighter jets, deploying naval vessels, and activating air defense missile systems.
In total, 19 Chinese military aircraft and seven naval vessels operated near the island during a 24-hour period. This event is part of an ongoing campaign of escalating pressure. During February alone, Taiwan recorded 253 Chinese military aircraft and 150 naval vessels within its air defense identification zone or adjacent waters.
Each incursion forces a response from Taiwan, consuming fuel, wearing down equipment, and straining personnel. The People’s Liberation Army is employing a strategy known as gray zone coercion.
This approach stops short of open warfare but extends beyond routine patrols, incorporating simulated attacks and sudden surges in military assets. The objective is to pressure Taiwan without provoking a full military response from the United States or its allies. Admiral Samuel Paparo, the U.S. nominee to lead Indo-Pacific Command, told Congress that the PLA has made significant advances in force levels and joint capabilities.
He warned that Beijing could disguise an invasion as a large-scale exercise, making early warning critical. The stakes extend beyond Taiwan’s immediate security.
The credibility of deterrence in the region is at risk. If the gray zone strategy succeeds in wearing down Taiwan’s defenses without direct conflict, the strategic balance shifts. Other nations observe whether Beijing can achieve its objectives without crossing the threshold that triggers international intervention.
The pattern of escalating pressure has been evident since 2020, and the February 29 incursion fits that pattern. Taiwan’s military activated missile systems and deployed jets and ships as it always does.
However, the cost of constant readiness is significant. Each incursion serves as a test, providing the PLA with data on Taiwan’s reaction times, defensive gaps, and capacity to sustain high alert. The median line, once a stable boundary, is now crossed at will by the PLA. Beijing claims Taiwan as part of its territory and has never renounced the use of force to achieve unification.
The 19 aircraft and seven ships observed on February 29 represent a single snapshot of a broader campaign of steady, grinding pressure. Taiwan’s defense posture remains reactive, responding to each incursion as it occurs.
The initiative lies with Beijing, which chooses when and where to surge forces. The PLA can mass quickly, simulate an attack one day, and pull back the next. Taiwan must maintain readiness every day.
Paparo’s congressional testimony highlighted the PLA’s capability to conduct a military operation disguised as an exercise. This ambiguity is central to the gray zone strategy, keeping both Taiwan and the United States uncertain while allowing Beijing to advance its position without triggering war.
The February 29 incursion represents another turn in this ongoing pressure campaign.
