Abstract: At the turn of the twenty-first century, several scholars characterized China as the “forgotten nuclear power.” This label derived from the oopacity surrounding China’s nuclear force and the assumed innocuousness of China’s force developments. Over the past decade, however, the tone of the conversation has changed as China has increased its transparency and capabilities. China is now the fourth-largest nuclear weapon state, and if it continues on its present trajectory, it will surpass France to become the third. It also has recently developed a credible nuclear triad. Many scholars argue that the increasing size and sophistication of China’s nuclear force should draw the attention of other nuclear weapon states and evoke calls for China’s participation in the disarmament conversation. This article explores what such cooperation might look like by highlighting the conditions likely to elicit Chinese participation.
