Nuclear Issues

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.

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.

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.

Whether they regard it as competitive, cooperative, or confrontational, virtually all observers agree that the U.S.-China relationship is consequential. From cyber norms and AI to military tensions in the Taiwan Strait and the global struggle to turn the tide on climate change, how Washington and Beijing manage their shared future will shape the globe for decades to come. Through research and relationship-building, the Center is dedicated to helping the U.S. and China collaborate and compete without conflict.

Soviet and American leaders learned during the Cuban Missile Crisis of October 1962 that inadequate communication raised perilous risks and dangers in the nuclear age. The US–Soviet Hotline was created soon thereafter, in 1963, and has operated continuously ever since. It was intended to provide a quick, reliable, confidential, ever-ready communications between heads of state in the event of crisis or war.  Hotlines remain a prudent, low-cost preparation that could prove essential in the event of a crisis that seems to be slipping out of 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.

Since 1983, China has had the objective of developing breeder reactors to run on recycled plutonium. Since 2004, it has been progressing through three stages of its plutonium recycling strategy: from pilot to demonstration to commercial facilities. At the first stage, in 2010, China began testing a pilot civilian reprocessing plant and running a small experimental fast reactor. Although those pilot facilities did not perform well, since 2015 China has moved forward to the second stage, which includes a demonstration reprocessing plant, a mixed-oxide fuel facility, and two demonstration liquid-sodium-cooled fast-neutron reactors. Recent satellite images and other information show construction of those demonstration facilities is actively underway. Meanwhile, the China National Nuclear Corporation is pushing toward the third stage by negotiating with France’s nuclear fuel cycle company Orano (formerly Areva) over the purchase of a large commercial reprocessing plant, and has proposed construction of large commercial fast-neutron reactors by 2028.

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.

Julius Weitzdörfer’s earliest childhood memories are the major global events of 1986—the Space Shuttle Challenger explosion and the Chernobyl disaster. Looking back, he realizes that these events must have contributed to shaping his later research interests in managing technological risks. 

China is developing new bombs, new missiles and new ways of launching them.
