Seeking China-U.S. Strategic Nuclear Stability

“To destroy the other, you have to destroy part of yourself.

To deter the other, you have to deter yourself,” according to a Chinese nuclear strategy expert. During the week of February 9^th, I had the privilege to travel to China where I heard this statement during the Ninth China-U.S. Dialogue on Strategic Nuclear Dynamics in Beijing. The Dialogue was jointly convened by the China Foundation for International Strategic Studies (CFISS) and the Pacific Forum Center for Strategic and International Studies (CSIS). While the statements by participants were not-for-attribution, I can state that the person quoted is a senior official with extensive experience in China’s strategic nuclear planning.

The main reason for my research travel was to work with Bruce MacDonald, FAS Adjunct Senior Fellow for National Security Technology, on a project examining the security implications of a possible Chinese deployment of strategic ballistic missile defense. We had discussions with more than a dozen Chinese nuclear strategists in Beijing and Shanghai; we will publish a full report on our findings and analysis this summer. FAS plans to continue further work on projects concerning China-U.S. strategic relations as well as understanding how our two countries can cooperate on the challenges of providing adequate healthy food, near-zero emission energy sources, and unpolluted air and water.

During the discussions, I was struck by the gap between American and Chinese perspectives. As indicated by the quote, Chinese strategic thinkers appear reluctant to want to use nuclear weapons and underscore the moral and psychological dimensions of nuclear strategy. Nonetheless, China’s leaders clearly perceive the need for such weapons for deterrence purposes. Perhaps the biggest gap in perception is that American nuclear strategists tend to remain skeptical about China’s policy of no-first-use (NFU) of nuclear weapons. By the NFU policy, China would not launch nuclear weapons first against the United States or any other state. Thus, China needs assurances that it would have enough nuclear weapons available to launch in a second retaliatory strike in the unlikely event of a nuclear attack by another state.

American experts are doubtful about NFU statements because during the Cold War the Soviet Union repeatedly stated that it had a NFU policy, but once the Cold War ended and access was obtained to the Soviets’ plans, the United States found out that the Soviets had lied. They had plans to use nuclear weapons first under certain circumstances. Today, given Russia’s relative conventional military inferiority compared to the United States, Moscow has openly declared that it has a first-use policy to deter massive conventional attack.

Can NFU be demonstrated? Some analysts have argued that China in its practice of keeping warheads de-mated or unattached from the missile delivery systems has in effect placed itself in a second strike posture. But the worry from the American side is that such a posture could change quickly and that as China has been modernizing its missile force from slow firing liquid-fueled rockets to quick firing solid-fueled rockets, it will be capable of shifting to a first-use policy if the security conditions dictate such a change.

The more I talked with Chinese experts in Beijing and Shanghai the more I felt that they are sincere about China’s NFU policy. A clearer and fuller exposition came from a leading expert in Shanghai who said that China has a two-pillar strategy. First, China believes in realism in that it has to take appropriate steps in a semi-anarchic geopolitical system to defend itself. It cannot rely on others for outside assistance or deterrence. Indeed, one of the major differences between China and the United States is that China is not part of a formal defense alliance pact such as the North Atlantic Treaty Organization (NATO) or the alliance the United States has with Japan and South Korea. Although in the 1950s, Chairman Mao Zedong decried nuclear weapons as “paper tigers,” he decided that the People’s Republic of China must acquire them given the threats China faced when U.S. General Douglas MacArthur suggested possible use of nuclear weapons against China during the Korean War. In October 1964, China detonated its first nuclear explosive device and at the same time declared its NFU policy.

The second pillar is based on morality. Chinese strategists understand the moral dilemma of nuclear deterrence. On the one hand, a nuclear-armed state has to show a credible willingness to launch nuclear weapons to deter the other’s launch.  But on the other hand, if deterrence fails, actually carrying out the threat condemns millions to die.  According to the Chinese nuclear expert, China would not retaliate immediately and instead would offer a peace deal to avert further escalation to more massive destruction. As long as China has an assured second strike, which might consist of only a handful of nuclear weapons that could hit the nuclear attacker’s territory, Beijing could wait hours to days before retaliating or not striking back in order to give adequate time for cooling off and stopping of hostilities.

Because China has not promised to provide extended nuclear deterrence to other states, Chinese leaders would also not feel compelled to strike back quickly to defend such states. In contrast, because of U.S. deterrence commitments to NATO, Japan, South Korea, and Australia, Washington would feel pressure to respond quickly if it or its allies are under nuclear attack. Indeed, at the Dialogue, Chinese experts often brought up the U.S. alliances and especially pointed to Japan as a concern, as Japan could use its relatively large stockpile of about nine metric tons of reactor-grade plutonium (which is still weapons-usable) to make nuclear explosives. Moreover, last July, the administration of Japanese Prime Minister Shinzo Abe announced a “reinterpretation” of the Article 9 restriction in the Japanese Constitution, which prohibits Japan from having an offensive military. (The United States imposed this restriction after the Second World War.)  The reinterpretation allows Japanese Self-Defense Forces to serve alongside allies during military actions. Beijing is opposed because then Japan is just one step away from further changing to a more aggressive policy that could permit Japan to act alone in taking military actions. Before and during the Second World War, Japanese military forces committed numerous atrocities against Chinese civilians. Chinese strategists fear that Japan is seeking to further break out of its restraints.

Thus, Chinese strategists want clarity about Japan’s intentions and want to know how the evolving U.S.-Japan alliance could affect Chinese interests. Japan and the United States have strong concerns about China’s growing assertive actions near the disputed Diaoyu Islands (Chinese name) or Senkaku Islands (Japanese name) between China and Japan, and competing claims for territory in the South China Sea. Regarding nuclear forces, some Chinese experts speculate about the conditions that could lead to Japan’s development of nuclear weapons. The need is clear for continuing dialogue on the triangular relationship among China, Japan, and the United States.

Several Chinese strategists perceive a disparity in U.S. nuclear policy toward China. They want to know if the United States will treat China as a major nuclear power to be deterred or as a big “rogue” state with nuclear weapons. U.S. experts have tried to assure their Chinese counterparts that the strategic reality is the former. The Chinese experts also see that the United States has more than ten times the number of deliverable nuclear weapons than China. But they hear from some conservative American experts that the United States fears that China might “sprint for parity” to match the U.S. nuclear arsenal if the United States further reduces down to 1,000 or somewhat fewer weapons.¹ According to the FAS Nuclear Information Project, China is estimated to have about 250 warheads in its stockpile for delivery.²Chinese experts also hear from the Obama administration that it wants to someday achieve a nuclear-weapon-free world. The transition from where the world is today to that future is fraught with challenges: one of them being the mathematical fact that to get to zero or close to zero, nuclear-armed states will have to reach parity with each other eventually.
