China's approach to nuclear deterrence has been broadly consistent since its first nuclear test in 1964. Key elements are its no-first-use policy and reliance on a small force of nuclear weapons capable of executing retaliatory strikes if China is attacked. China has recently accelerated nuclear force building and modernization, and both international and domestic factors are likely to drive faster modernization in the future. Chinese nuclear planners are concerned by strategic developments in the United States, especially the deployment of missile defenses. Within the region, Beijing is also an actor in complex multilateral security dynamics that now include several nuclear states, and the improving nuclear capabilities of China's neighbors, especially India, are a growing concern for Beijing. Constituencies for nuclear weapons have gained in bureaucratic standing within the People's Liberation Army (PLA). With few, if any, firewalls between China's conventional and nuclear missile forces, new technologies developed for the former are already being applied to the latter, a trend that will almost certainly continue. Given these changes, China is likely to increase emphasis on nuclear deterrence, accelerate nuclear force modernization, and make adjustments (although not wholesale changes) to policy.
