China’s People’s Liberation Army (PLA) has commenced a significant series of military exercises around Taiwan, under the codename Justice Mission 2025. These large-scale drills include live-fire exercises, naval deployments, fighter jet sorties, and artillery strikes, simulating blockade operations and joint attacks. The move has sharply escalated tensions across the Taiwan Strait.
Details of the Drills
On December 29, 2025, the PLA Eastern Theater Command activated combined forces from the army, navy, air force, and rocket units to conduct extensive joint military maneuvers encircling Taiwan. Highlights of the drills include:
- Live-fire exercises planned for December 30 in designated restricted maritime and airspace zones.
- Simulations of blockading major ports such as Keelung and Kaohsiung, alongside efforts to seize control of sea and air domains.
- Coordinated strikes against both maritime and land targets to demonstrate integrated combat capabilities.
- Release of propaganda materials titled “Shields of Justice: Smashing Illusions” and “Arrows of Justice: Control and Denial,” emphasizing deterrence against foreign interference and separatist forces.
The PLA characterized these drills as a “stern warning” to what it describes as “Taiwan independence separatists” and foreign powers interfering in China’s sovereignty. Beijing insists such exercises are vital to protect national unity.
Taiwan’s Reaction
In response, Taiwan’s Ministry of National Defense swiftly mobilized its forces, raising alert levels and conducting rapid response drills. Taiwan also publicly showcased advanced U.S.-supplied weaponry, including HIMARS rocket systems, to signal its preparedness for any potential aggression.
Taiwan condemned the exercises as “irresponsible provocations” that threaten regional stability. Government officials reaffirmed that Taiwan’s future is solely a matter for its people to decide, firmly rejecting Beijing’s claims over the island.
Context and Triggers
This marks the sixth major PLA military drill encircling Taiwan since 2022. Analysts point to several key triggers behind the timing:
- The recent approval of a substantial $11 billion U.S. arms sale to Taiwan earlier this month.
- Rising tensions with Japan following remarks hinting at possible Japanese involvement in any Taiwan conflict.
Beijing perceives these developments as direct interference in its internal affairs, maintaining that Taiwan is an inseparable part of China.
Wider Implications
The drills underline China’s growing ability to impose a military blockade and isolate Taiwan strategically, blurring the lines between training exercises and real combat scenarios. While an invasion is not immediately expected, the frequency and scale of these drills heighten the risk of miscalculation in an already sensitive region.
Regional stability remains fragile as the United States and its allies closely monitor the evolving situation. Meanwhile, Taiwan continues to bolster its defenses amid mounting pressure from Beijing.
