Defence — China · Synthesis
The world's second-largest military budget, undergoing rapid modernization, with the largest navy in the world by number of vessels and a rapidly expanding nuclear arsenal — the primary military dynamic on the planet.
Citoyen synthesis for the Defence category in China. Grounded in available quantitative data (official budget, SIPRI and IISS estimates). ⚠️ Warning: the official defence budget is considered to understate actual spending (SIPRI publishes higher estimates), and opacity is high. All values are the latest realized observation available. Data last updated: June 2026.
1. State of play — where China's defence stands
The world's second-largest military budget. Chinese military spending amounts to approximately 300 to 340 billion dollars (SIPRI estimates, ≈ 1.5% of GDP), the second-largest budget in the world after the United States. ⚠️ The announced official budget is lower than SIPRI estimates, which incorporate spending outside the stated budget.
Rapid modernization. The People's Liberation Army (PLA) is undergoing rapid modernization: navy, air force, missiles, space, cyber. China now has the world's largest navy by number of vessels — a build-up that is reshaping the military balance in the Indo-Pacific.
A rapidly expanding nuclear arsenal. Long possessed of a modest nuclear arsenal, China is now undergoing the world's fastest nuclear expansion (Federation of American Scientists, SIPRI), with the construction of new silos and an increase in the number of warheads — a major strategic shift.
Taiwan, the focal point. Military pressure on Taiwan (exercises, incursions) and tensions in the South China Sea are at the heart of China's posture and of tensions with the United States and their allies (see the Defence notes for the United States and Japan).
A rising defence industry. China's defence industry is growing in strength and becoming an exporter, even though it remains behind the major Western suppliers and Russia on certain segments.
“The world's second-largest military budget, China is modernizing its armed forces at a pace that worries its neighbours and the United States.”
2. Outlook — where defence is heading
Competition with the United States. Military rivalry with the United States, particularly in the Indo-Pacific, structures the Chinese trajectory (modernization, navy, missiles, disruptive technologies).
Nuclear expansion. The continued expansion of the nuclear arsenal is being closely monitored by the international community, altering the global deterrence balance.
Taiwan. The evolution of pressure on Taiwan is the primary regional and global geopolitical risk factor.
Opacity. The opacity of the budget and actual capabilities makes assessment difficult; estimates rely largely on external sources (SIPRI, IISS).
The open questions. Three points will structure the reading: (1) competition with the United States; (2) nuclear expansion; (3) pressure on Taiwan.
“Its nuclear arsenal, long modest, is now undergoing the fastest expansion in the world.”
3. International comparison — China among the military powers
Placed in its environment, China is the world's second military power and the fastest-growing dynamic, narrowing the gap with the United States in its region.
Three takeaways. (1) Second budget, far behind the United States. At ≈ 300-340 bn$, China spends roughly three times less than the United States (≈ 900-970 bn$), but far more than Russia, India or the European powers.
(2) A nuclear build-up. Unlike the stable arsenals of the other powers, China is rapidly expanding its own — a major shift in the strategic balance.
(3) Opaque data. Unlike the budgets of democracies, China's actual spending is estimated and under-declared — comparisons subject to reservation.

Methodological note — the synthesis keeps sourced facts distinct from assessments, stays neutral, dates each figure, and does not extrapolate beyond the sources. ⚠️ Specific warning: the official Chinese budget is considered to understate actual spending (higher SIPRI estimates used); high opacity. All values are the latest realized observation available (no forecast). Note generated by AI, human review required. Same safeguards as the rest of the observatory.
