The Pentagon assesses that China’s production of nuclear warheads has slowed after a rapid buildup since 2020, with fewer new weapons added to its arsenal over the last year. However, Beijing’s program continues to expand in other critical areas, focusing on lower-yield nuclear weapons and early counterstrike capabilities, and remains on track to field 1,000 warheads by the end of the decade.
Why it matters
The China Military Power Report — an annual unclassified Pentagon assessment of Beijing’s capabilities delivered to Congress — departs significantly from the language of recent editions. While previous reports emphasized the looming challenge of China’s military buildup, this year’s document highlights President Donald Trump’s efforts to stabilize ties with the world’s fastest-growing military power.
The report strikes an overall more conciliatory tone regarding Beijing’s military ambitions. Where last year’s assessment described Beijing as the “pacing challenge” for the U.S. military, this year’s report describes China’s rapidly expanding military as a “logical” result of the country growing more wealthy and powerful.
“President Trump seeks a stable peace, fair trade, and respectful relations with China, and the Department of War will ensure that he is able to achieve these objectives,” the report reads.
What to know
According to the assessment, Beijing’s total nuclear warhead arsenal likely remained in the low 600s, a figure similar to last year. This reflects a “slower rate of production,” down from the estimated 100 additional warheads a year observed since 2020. Despite this slowdown, the report notes that the People’s Liberation Army (PLA) is continuing “its massive nuclear expansion” and showing “no appetite” for arms control discussions.
The report details that while raw numbers have stabilized, China’s broader nuclear program has expanded in sophistication. This includes the development of more versatile low-yield weapons and upgrades to counterstrike systems. The Pentagon notes that China has likely loaded more than 100 intercontinental ballistic missiles into desert silos, advancing capabilities for long-range strikes closer to U.S. territories.
At over 600 nuclear warheads, China’s arsenal remains far smaller than the U.S. stockpile of about 3,700. However, the report indicates that upgrades in China’s program likely have enhanced its ability to rapidly retaliate. “This reliance on the strategic level of deterrence — likely nuclear weapons, but also cyber and space capabilities — indicates the growing confidence and comfort the PLA has with conventional escalation,” the report states.
Despite the shift in diplomatic tone, the document lays out mounting challenges posed by Beijing’s ambitions to assert control over Taiwan and expand a conventional missile force that is increasingly approaching U.S. capabilities. The Pentagon report notes that Beijing is ramping up efforts to “coerce” Taiwan to unify with China through a campaign of military patrols — including a twofold increase in incursions into Taiwan’s air defense identification zone between 2023 and 2025.
What people are saying
Analysts suggest the report highlights the difficulties facing the Trump administration as it attempts to balance prioritizing U.S. trade interests while projecting military dominance in the Indo-Pacific.
“There’s an inherent contradiction running through the report: it lays bare the scale of China’s military expansion and Taiwan ambitions while simultaneously suggesting the relationship is stabilizing,” said Craig Singleton, senior China fellow at the Foundation for Defense of Democracies. “Those two stories can’t be reconciled — no matter how hard the administration tries to preserve the trade truce.”
Others point to internal factors within China as a reason for the production shift. “Beijing may currently perceive a reduced existential threat from the United States and, accordingly, less urgency to pursue nuclear expansion at maximum speed than during the peak of U.S.-China hostility around 2021,” said Tong Zhao, a nuclear specialist and senior fellow at the Carnegie Endowment for International Peace.
Zhao added that China’s 2023 overhaul of the PLA Rocket Force following a corruption scandal could mean the country is working to “prioritize internal reform and more sustainable, effective long-term growth.”
Regarding technology transfers, Singleton criticized recent policy shifts. “The Pentagon is warning that China already treats advanced accelerators as a strategic asset — using intermediaries and shell networks to evade controls — so the White House’s desire to reopen the export spigot is strategically backward,” he said. “It turns an enforcement problem into a policy choice that strengthens exactly the capability the report flags as a growing threat.”
What happens next
The annual military assessment arrives as President Trump prepares to travel to Beijing next year. This follows a trade détente reached with Chinese leader Xi Jinping in South Korea that eased tensions over Trump’s aggressive tariff program and Beijing’s weaponization of its rare-earth monopoly.
However, national security frictions continue to flare. Beijing recently reacted angrily to the U.S. seizure of a Venezuelan oil tanker en route to China and strongly condemned the approval of a record $11 billion U.S. weapons package for Taiwan.
Furthermore, the Arms Control Association notes that the significance of China’s expanding arsenal is being viewed through the lens of rising global tensions. Russia has stepped up nuclear intimidation since its invasion of Ukraine, while Trump has ordered the United States to resume nuclear testing “immediately,” accusing Moscow and Beijing of skirting a three-decade moratorium.
The White House is signaling shifting priorities through its recently released National Security Strategy, which frames the China challenge more in economic terms while pivoting the U.S. focus toward threats in the Western Hemisphere. The Pentagon report warns, however, that illicit smuggling networks have likely allowed companies such as Deepseek and Huawei to obtain U.S. semiconductors for projects with potential military significance in AI and quantum technology.
