Taiwan Conducts Major Military Drills as China Invasion Threat Looms
Taiwan ran annual war games simulating a Chinese assault, extended exercises to the Penghu islands, and throttled mobile internet for the first time during the drills.
Taiwan launched its annual military exercises this week with a clear framing: rehearsal for a Chinese invasion. The war games extended to the strategically critical Penghu island chain and included an unprecedented step — Taiwan throttled civilian mobile internet access for the first time during the exercises, according to Reuters, reporting on the exercises covered by Al Jazeera and Fox Business.
The network throttling — a first for Taiwan’s annual war games — signals a sharpened focus on wartime communications resilience. Military planners have long assumed a Chinese operation would target civilian infrastructure in the opening hours of any assault, using electronic warfare, cyberattacks, or physical strikes on undersea cables and cell towers. By deliberately degrading mobile connectivity during live exercises, Taiwan’s forces tested whether command networks, emergency services, and civilian agencies can operate under those conditions.
Penghu: Forward Defense in the Strait
The extension of this year’s exercises to the Penghu archipelago reflects the operational logic driving Taiwan’s defense planning. The roughly 90 islands of Penghu sit midway between Taiwan’s main island and China’s Fujian coast, directly athwart the shipping lanes and invasion corridors the People’s Liberation Army would need to traverse in any large-scale amphibious operation.
Securing or contesting Penghu would be a prerequisite for either side in a Taiwan Strait conflict. For the PLA, the islands represent a potential forward staging area; for Taiwan’s defenders, holding them delays and complicates any assault on the main island. Running exercises there tests the logistics, communications, and reinforcement chains that a real defense would demand.
Layered Preparations
The drills arrive as Taiwan has been methodically building out its defense posture on multiple fronts. Defense spending has climbed to record levels this year, as this publication reported earlier this week, with procurement focused on asymmetric capabilities — missiles, drones, and hardened command infrastructure — rather than large-platform conventional forces.
Taiwan’s strategic planners have been open about their interest in the so-called hellscape concept: flooding the Taiwan Strait with autonomous systems in the opening hours of a conflict to deny the PLA the operational window it would need to establish a beachhead. A detailed look at that drone strategy published last week outlined how U.S. and Taiwanese defense thinkers have developed those contingency plans.
The war in Ukraine has provided a live field test of many of the same principles. Ukraine’s military has used drone saturation, dispersed logistics, and layered air defense to blunt a larger conventional force — and its long-range strike campaign against Russian infrastructure has demonstrated how relatively cheap autonomous systems can impose costs deep inside an adversary’s territory. Taiwan’s defense establishment has been watching closely.
Beijing’s Position
China’s government has not issued a formal statement specifically addressing this year’s exercises. Beijing routinely characterizes Taiwan’s military activities as provocative, and the PLA has historically shadowed Taiwan’s annual war games with naval movements and air incursions near the island’s air defense identification zone.
Xi Jinping has made the question of Taiwan’s reunification with China a defining political objective, describing it as a historical inevitability. Chinese defense spending and PLA modernization have accelerated sharply over the past decade, with particular investment in amphibious lift capacity, ballistic and cruise missile arsenals, and carrier-based aviation — all capabilities relevant to a Taiwan scenario.
Taiwan’s defense ministry has consistently assessed that the risk window is narrowing, though analysts disagree on timelines. The island’s military has framed these exercises not as deterrence theater but as genuine operational preparation.
Reading the Signals
Annual military exercises serve multiple audiences simultaneously. For Beijing, they are a signal that Taiwan’s forces remain capable and that any military operation would carry real costs. For Washington, they demonstrate that Taiwan is investing in its own defense rather than relying entirely on U.S. intervention. For Taiwan’s own population, they are a reminder that the threat across the strait is not abstract.
The decision to throttle mobile internet during this year’s games adds a layer beyond the usual. It suggests Taiwan’s planners have moved past optimistic assumptions about infrastructure availability in a conflict scenario and are building muscle memory for degraded conditions. Ukraine’s experience — where Russian strikes on power grids, communications nodes, and refinery infrastructure have been a sustained feature of the war — has made that kind of planning harder to defer.
Whether the exercises shift Beijing’s calculus is an open question. They are unlikely to deter a Chinese decision driven by political or strategic imperatives. What they do is reduce the probability that Taiwan’s forces would be caught unprepared, and narrow the window in which a rapid fait accompli might succeed before outside intervention could arrive.
