Among the many issues surrounding China’s ongoing military modernization, perhaps none has been more dramatic than its nuclear weapons program. For decades, the Chinese government was content to maintain a comparatively small nuclear force. As recently as 2020, China’s arsenal was little changed from previous decades and amounted to some 220 weapons, around five to six percent of either the U.S. or Russian stockpiles of deployed and reserve warheads.

| Spring 2023

Chinese strategists increasingly believe that U.S. nonnuclear strategic capabilities threaten China’s nuclear forces. Although there is limited evidence of a shift in its nuclear strategy, China is changing its strategic posture to ensure its second-strike capability, including by relying on advanced conventional weapons (e.g., counterspace capabilities, cyber weapons, and electronic warfare) that can target U.S. missile defense. The dynamics of a nuclear-conventional entangled security dilemma may weaken arms race stability.

Then What? Assessing the Military Implications of Chinese Control of Taiwan

| Summer 2022

An analysis of Taiwan’s military value concludes that its reunification with China would improve Chinese submarine warfare and ocean surveillance capabilities, tipping the military balance in China’s favor. These findings have important implications for U.S. operational planning, policy, and grand strategy.

Assessing China-U.S. Inadvertent Nuclear Escalation

| Winter 2021/22

Could a conventional war between China and the United States escalate to the nuclear level? An assessment of three mechanisms of China-U.S. inadvertent escalation—use-it-or-lose-it, unauthorized/accidental, and damage limitation—concludes that the risk of China-U.S. inadvertent nuclear escalation is extremely low.

'What About China?' and the Threat to US–Russian Nuclear Arms Control

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

Living with Uncertainty: Modeling China's Nuclear Survivability

| Spring 2020

A simplified nuclear exchange model demonstrates that China’s ability to launch a successful nuclear retaliatory strike in response to an adversary’s nuclear first strike has been and remains far from assured. This study suggests that China’s criterion for effective nuclear deterrence is very low.
