China’s defense spending soars: A signal of global ambition or structural constraints?

Beijing's recent 7.2% increase in its defense budget, outpacing GDP growth, continues a long-standing trend in China’s strategic trajectory. While official narratives frame this expansion as vital for national security and technological modernization, the scale and scope of this spending suggest a broader ambition: building a military capable of projecting power beyond its traditional spheres of influence. The People’s Liberation Army (PLA) is no longer focused solely on Taiwan or border security but is evolving into a force with far-reaching operational capabilities, signaling China’s intent to shape the Indo-Pacific and beyond.

However, behind these headline figures lies a more complex reality—one that balances China’s external ambitions with internal vulnerabilities. Corruption scandals, political purges, and systemic inefficiencies within the PLA raise critical questions about whether China’s military modernization is truly sustainable. High-profile dismissals in the Rocket Force and defense procurement sectors expose deep-rooted issues, which could undermine Beijing’s military expansion, even as its budget grows.

Signals of Global Ambition

At the heart of China’s decades-long surge in defence spending has been its evolving strategic doctrine, which prioritizes both regional dominance and extra-regional military presence. Xi Jinping’s push to build a “world-class military” by 2049 is not merely aspirational rhetoric, but has served as an operational blueprint for China’s global military projection. The budget increase directly funds naval expansion, defence technology advancements, and an increasingly assertive military diplomacy, each reinforcing Beijing’s ability to exert influence well beyond the Taiwan Strait and the South China Sea.

A key aspect of this transformation has been the PLA Navy’s expanding blue-water capabilities. With the construction of new aircraft carriers, nuclear submarines, and a network of overseas logistical hubs, China is laying the foundation for sustained global military operations. Beijing’s approach also resembles historical great-power strategies, leveraging economic and military instruments to reinforce one another.

This ambition was particularly evident in China’s “dual-use” approach, where economic and civilian infrastructure projects serve in compliment to military functions. The Belt and Road Initiative (BRI) has also provided Beijing access to key logistics hubs, some of which now serve as potential military assets. Djibouti, the Solomon Islands, and Cambodia’s Ream Naval Base exemplify this shift, each allowing China to extend its operational reach.

China’s defence expansion also carries profound strategic consequences for regional security architectures. Countries such as India, Australia, and Japan—already wary of Beijing’s maritime assertiveness— now face the challenge of responding to a PLA will soon no longer remain geographically constrained. China’s recent naval drills near Australia and New Zealand further illustrate this shift; these exercises are not merely routine military manoeuvres but an attempt to normalize Beijing’s presence in previously uncontested waters.

Beyond Asia, China's expanding military capabilities has also reshaped the balance of power in global security affairs. Unlike the Soviet Union during the Cold War, China had been leveraging economic interdependence to temper direct military pushback while simultaneously expanding its military clout. This now complicates deterrence strategies for the United States and its allies, as economic considerations often continue to conflict with the imperatives of countering China’s military rise.

Beijing's growing defence budget is thus not solely a response to internal security needs but a broader declaration of intent. The challenge for other states is now one of recognizing that China’s military expansion is not just about Taiwan, border security, or regional hegemony, but is also about establishing a force capable of shaping global security dynamics on its own terms. The coming years will determine whether the international community can either adapt to this new strategic reality or remain reactive to China’s shifting military posture.

Internal Challenges Within the PLA: Corruption and Power Consolidation

While China’s rising defence budget signals an aggressive military expansion, internal developments within the PLA paint a more complicated picture. Recent high-profile corruption scandals exposing deep-rooted weaknesses within the military’s senior ranks, also raises serious concerns about the effectiveness of China’s military buildup.
The removal of senior officials from the Rocket Force, the unit responsible for China’s nuclear and missile capabilities, suggests that Xi Jinping’s military modernization drive has not just been about hardware and expansion but is as much about internal control and Party discipline. That said, despite a decade of anti-corruption campaigns, the persistence of graft and political favouritism has led to the presumption that these issues continue to remain systemic rather than isolated incidents.

Corruption within the PLA has been a longstanding issue, rooted in its history as a patronage-driven organization under China’s pre-reform command economy. The recent wave of dismissals, despite Xi Jinping’s relentless anti-graft efforts, also raises troubling questions about institutional accountability. 

This internal instability carries significant implications for China’s military readiness and strategic ambitions. First, it leads to questions about combat readiness, particularly in key strategic areas such as missile deterrence and naval operations. If procurement fraud, resource misallocation, and loyalty-based promotions continued to plague the PLA, its ability to execute complex military operations can potentially be compromised. Irrespective of growing financial investments, corruption will end up eroding unit cohesion, discipline and trust in command structures.

Second, it underscored the increasing centralization of power under Xi Jinping, who has prioritized political loyalty over professional military competence. This shift also risks creating a command culture that values ideological alignment over operational effectiveness, potentially weakening China’s ability to respond decisively.

Finally, a military plagued by internal purges and instability will struggle to sustain the level of global power projection that Beijing has envisioned so far. If China’s top military brass remains vulnerable to frequent reshuffling and political crackdowns, the PLA might find it difficult to cultivate the institutional stability required for long-term strategic execution.

A Military Expansion with Limits?

China’s rapidly increasing defence expenditures clearly signal an ambition to transform the PLA into a dominant global force. However, this ambition is not without serious structural constraints. The persistence of corruption, political interference and command instability diverts focus to the fact that China’s military rise might be less linear and more fragile than what budgetary figures imply.

While Beijing has sought to redefine global military balances, its internal military struggles could limit the effectiveness and sustainability of this expansion. Whether China could resolve these institutional challenges without compromising operational efficiency remains an open question. For the international community, this paradox presents both a challenge and an opportunity—one that requires focus on their ability to anticipate China’s growing military reach while also recognizing the constraints that will shape Beijing’s strategic trajectory in the years to come. Ratish Mehta (Research Associate at Organisation for Research on China and Asia (ORCA))
