In defense policy circles and grand strategy discussions across Washington, Tokyo, New Delhi, and Brussels, an uncomfortable historical analogy has surfaced with increasing frequency: China is executing the fastest, most comprehensive peacetime military buildup seen in the international system since the rearmament of the major powers in the 1930s. Under General Secretary Xi Jinping, the People’s Liberation Army (PLA) has evolved from a bloated, continental infantry force into a technologically advanced, multi-domain juggernaut capable of projecting power well beyond the First Island Chain.
The scale of this rearmament is staggering. China operates the world’s largest navy by total hull count, commands an arsenal of precision anti-ship and hypersonic ballistic missiles with no Western equivalent, fields hundreds of fifth-generation stealth fighters, and is accelerating the expansion of its nuclear triad toward an estimated 1,500 warheads over the coming decade. Yet understanding this phenomenon requires looking past hardware figures. Why is Beijing pursuing rearmament on such an unprecedented scale, and what strategic imperatives drive Xi Jinping’s military machine?
The Ideological Mandate: “Great Rejuvenation” and Century-Old Grievances
At the philosophical core of China’s military surge is Xi Jinping’s ideological vision: the “Chinese Dream of National Rejuvenation” (中华民族伟大复兴). In the narrative curated by the Chinese Communist Party (CCP), modern China’s mission is to overcome the legacy of the “Century of Humiliation”—a period spanning from the first Opium War in 1839 to the founding of the PRC in 1949, during which Western empires and Imperial Japan repeatedly defeated, partitioned, and exploited China.
Xi has repeatedly stated that national rejuvenation cannot be accomplished without a military equal to China’s economic stature. In Party doctrine, economic power without hard military deterrence creates vulnerability. To ensure that China never again submits to foreign pressure, Xi set explicit benchmarks: achieve basic military modernization, complete comprehensive modernization to field a “world-class military” by the centenary of the PRC, and build operational readiness around near-term strategic objectives.
The Taiwan Question: Securing Core Geopolitical Ambitions
While ideology provides the rhetorical foundation, Taiwan is the operational anchor of China’s military transformation. Beijing regards Taiwan as an inalienable province that must eventually be reunited with the mainland, by negotiation if possible, but by brute force if necessary.
For decades, the United States maintained decisive deterrence across the Taiwan Strait because the PLA lacked the lift capacity, amphibious armor, air superiority, and command-and-control systems to execute a cross-strait assault against an American intervention. Under Xi, Beijing restructured the entire military to overturn this dynamic:
- Anti-Access/Area-Denial (A2/AD): Through the PLA Rocket Force, China deployed long-range anti-ship ballistic missiles (such as the DF-21D and DF-26 “carrier killers”) designed to keep American carrier strike groups beyond combat range.
- Naval Preponderance: The PLA Navy (PLAN) underwent a shipbuilding frenzy, launching guided-missile cruisers (Type 055), amphibious assault carriers (Type 075/076), and electromagnetic catapult-equipped aircraft carriers to dominate the surrounding waters.
- Joint Operational Command: In the 2015–2016 structural reforms, Xi dissolved antiquated military regions and created unified Theater Commands, ensuring ground, air, naval, and missile assets could coordinate combined-arms operations under a single command.
The goal of this buildup is coercive leverage: establishing a conventional balance of power so lopsided that Taipei capitulates and Washington concludes that the operational cost of intervening is prohibitive.
Dismantling the Pax Americana: Reshaping the Global Order
Beyond the immediate theater of Taiwan and the South China Sea, Xi Jinping views international relations through the lens of structural great-power competition. Beijing’s grand strategy seeks to transition the world away from a unipolar order dominated by the United States and its alliance networks toward a multipolar system where China commands its own sphere of influence.
Xi believes that the international architecture established post-World War II disproportionately favors Western norms, values, and security interests. To counter U.S. freedom-of-navigation patrols, forward-deployed bases in Japan and South Korea, and emerging regional partnerships (like the Quad and AUKUS), China needs an expeditionary force capable of protecting its trade routes, securing foreign ports under the Belt and Road Initiative, and sustaining blue-water operations across the Indian Ocean and Middle East.
A massive military signals to nations across the Global South that the international balance of power has shifted, offering an authoritarian superpower capable of backing diplomatic and economic partnerships with raw strategic mass.
The “Peak China” Theory and the Window of Vulnerability
An alternative analysis popular among strategic scholars focuses on the concept of “Peak China.” Rather than expanding from a position of boundless confidence, Xi Jinping may be accelerating military capacity because he recognizes that China’s window of strategic opportunity is narrowing.
China faces deep structural challenges at home:
- Demographic Contraction: Decades of the One-Child Policy have produced a rapidly aging society, shrinking the workforce and intensifying long-term strain on state finances.
- Economic Deceleration: The property sector crisis, mounting local government debt, and slowing productivity have ended the era of double-digit GDP expansion.
- Technological Containment: Advanced semiconductor export controls and western “de-risking” efforts threaten to constrain China’s next-generation industrial advancements.
Recognizing that Beijing may never again possess as much relative economic and industrial capacity vis-à-vis the West as it does right now, Xi’s administration has frontloaded military procurement to cement China’s strategic position before demographic and structural economic headwinds fully bite.
Domestic Consolidation and Regime Security
Finally, the military expansion serves an essential domestic purpose. In Leninist party-states, the military is not an apolitical national defense force; the PLA is the armed wing of the Chinese Communist Party.
When Xi took power in 2012, he found a military riddled with corruption, with generals selling commissions and skimming from defense logistics. Through aggressive anti-corruption purges and sweeping structural realignments, Xi removed potential political rivals, restructured the Central Military Commission (CMC), and reaffirmed the foundational principle that “the Party commands the gun”.
By investing hundreds of billions of dollars into high-tech weaponry, modern living quarters, and prestigious naval fleets, Xi elevated the status of the military while securing its complete institutional loyalty to his personal leadership. The buildup reinforces nationalist legitimacy at home, presenting a strong leader capable of defending the motherland against external containment.
The Strategic Dilemma
Xi Jinping’s military buildup is driven by historical grievances, geopolitical revisionism, regime survival, and an acute calculation of shifting global power dynamics. By constructing a military machine of historic proportions, Beijing has dramatically altered the security calculus of the Indo-Pacific. Whether this buildup ultimately deters major conflict through unmatched conventional strength or accelerates a catastrophic clash among nuclear powers remains the central geopolitical question of our time.
