As global attention concentrates on the Middle East and Ukraine, China is steadily increasing military pressure on Taiwan — a slow-motion crisis with profound global consequences
The Crisis That Moves Too Slowly for Headlines
Gradual escalation consistently loses to acute crisis in the competition for international attention. The sudden strike, the announced invasion, the dramatic collapse — these events mobilise news cycles and diplomatic responses. The slow, incremental expansion of military pressure, conducted deliberately below the threshold that would trigger coordinated international reaction, is harder to cover and harder to respond to — and potentially more consequential precisely because it lacks the dramatic clarity that acute crises possess.
The Taiwan Strait is currently the site of exactly this kind of gradual escalation. Since 2020, the frequency, scale, and geographic scope of Chinese People’s Liberation Army military operations around Taiwan have increased across every measurable dimension — aircraft incursions into Taiwan’s Air Defense Identification Zone, naval exercises simulating a blockade, the development of military infrastructure on China’s southeastern coast, and the pace of PLA modernisation oriented toward a Taiwan contingency operation. None of these individually crosses the threshold of an acute crisis. Cumulatively, they represent a sustained reshaping of the strategic environment surrounding the most economically significant contested territory on earth.
China’s Calibrated Pressure Strategy
The Normalisation Objective
China’s military pressure on Taiwan does not appear designed, in its current phase, to achieve rapid coercion. A cross-strait invasion would be extraordinarily complex militarily, with very high costs even in a successful scenario and potentially catastrophic consequences if it failed or produced prolonged resistance. What the pressure campaign appears designed to achieve is normalisation — the gradual habituation of Taiwan’s population, regional observers, and the international community to Chinese military presence as a permanent strategic reality rather than an exceptional event.
Each exercise, repeated with sufficient frequency, becomes unremarkable. Each record for aircraft incursions, broken regularly enough, becomes the new baseline. With normalisation comes the slow erosion of the shock value that genuine escalation would produce — and the reshaping of the psychological and political environment in which decisions about resistance and accommodation are ultimately made. This long-term erosion of strategic confidence, rather than rapid military coercion, may be the primary near-term objective of China’s sustained pressure campaign.
| 1,700+ PLA aircraft incursions into Taiwan’s Air Defense Identification Zone in 2023 Each incursion requires Taiwan’s air force to scramble interceptors, consuming pilot flight hours, aircraft airframe life, fuel, and maintenance resources. Over hundreds of scrambles annually, the cumulative operational burden on a force that is significantly smaller than the PLAAF it faces is strategically meaningful. |
| “Grey zone strategies exploit the gap between what is happening militarily and what political and diplomatic systems are calibrated to respond to. By the time the cumulative effect of sustained grey zone pressure becomes undeniable, the strategic situation has already shifted substantially.” — Dr. Oriana Skylar Mastro Center Fellow, Freeman Spogli Institute for International Studies, Stanford University |
The Airspace and Naval Dimensions
The Air Defense Identification Zone is not sovereign airspace — it is a unilaterally declared zone within which states require incoming aircraft to identify themselves for early warning purposes. Incursions into Taiwan’s ADIZ do not, by themselves, constitute violations of international law. But the scale and character of Chinese ADIZ operations have evolved well beyond routine military activity. H-6K strategic bombers, J-20 fifth-generation fighters, Y-8 anti-submarine aircraft, and electronic intelligence platforms regularly participate in coordinated multi-aircraft formations that traverse portions of the ADIZ closest to Taiwan’s main island.
Naval exercises have grown in parallel. Large-scale PLA Navy exercises surrounding Taiwan have simulated blockade operations, amphibious assault preparation, and the suppression of defending air forces. The geographic scope of these exercises has expanded progressively, with some encompassing areas well east of Taiwan that would be relevant to operations designed to prevent US naval intervention. The cumulative effect has been the normalisation of large-scale PLA military activity in Taiwan’s immediate strategic environment in ways that would have been considered extraordinarily provocative a decade ago.
The Semiconductor Dimension
Taiwan’s strategic significance extends well beyond its geopolitical position or the symbolic importance of its democratic system. Taiwan produces approximately 90 percent of the world’s most advanced semiconductor chips through TSMC and its manufacturing ecosystem — chips embedded in every advanced technology product, from consumer electronics to military systems to the AI computing infrastructure driving the next industrial revolution. Any conflict degrading Taiwan’s chip manufacturing capacity would trigger a global technology supply chain crisis of a scale and duration dwarfing the COVID-era semiconductor shortage.
| ~90% of the world’s most advanced semiconductor chips are manufactured in Taiwan TSMC alone produces the chips at the leading edge of global computing technology. Economic research estimates the GDP impact of a year-long disruption to Taiwan’s chip manufacturing at approximately $1 trillion globally — a figure that understates the compounding effects across technology-dependent industries. |
| “TSMC’s fabs represent an irreplaceable concentration of the world’s most advanced manufacturing capability. The global economy does not have a contingency plan for their sustained disruption. That is not a comfortable strategic position for anyone with an interest in technological continuity.” — Chris Miller Associate Professor of International History, Tufts University; Author, Chip War: The Fight for the World’s Most Critical Technology |
The Alliance Response
The United States has moved progressively away from studied strategic ambiguity, increasing arms sales to Taiwan, strengthening military consultation, and allowing senior officials to make statements suggesting a willingness to defend Taiwan militarily — departures from previous policy formulations that have been subsequently qualified but not retracted. Japan has explicitly stated in defence policy documents that a Taiwan contingency would directly affect Japanese national security, a significant statement given Japan’s geographic proximity. Australia’s AUKUS partnership and its associated submarine capability programme is primarily oriented toward the Indo-Pacific strategic environment.
The Quad — the informal security dialogue among the US, Japan, Australia, and India — has elevated Taiwan-adjacent security concerns while maintaining diplomatic ambiguity about formal commitments. The cumulative effect of these alliance responses has been to strengthen deterrence credibility, while the challenge of managing the tension between deterrence and avoiding actions that Beijing interprets as sufficient provocation to accelerate rather than delay aggressive action remains the central challenge of alliance management in the Taiwan Strait context.
Conclusion: The Slow Crisis and Its Global Implications
The intersection of sustained grey zone pressure with Taiwan’s irreplaceable role in global semiconductor manufacturing is what makes the Taiwan Strait one of the most consequential geopolitical situations of our time. The world’s technological and economic future runs through a small island’s manufacturing ecosystem that sits at the centre of the most significant unresolved territorial dispute in the Indo-Pacific. Managing that reality — maintaining deterrence, supporting Taiwan’s resilience, preserving the semiconductor supply chain on which global technological progress depends, and doing all of this without triggering the escalation that deterrence is designed to prevent — is among the most complex strategic challenges of the current era.
