Reluctant Restraint examines one of the most important changes in Chinese foreign policy since the country opened to the world: China's gradual move to support the nonproliferation of nuclear weapons, missiles, and their related goods and technologies. Once a critic of the global nonproliferation regime, China is now a supporter of it, although with some reservations. Medeiros analyzes how and why Chinese nonproliferation policies have evolved so substantially since the early 1980s. He argues that U.S. diplomacy has played a significant and enduring role in shaping China's gradual recognition of the dangers of proliferation, and in its subsequent altered behavior.
