Though China remains a relatively weak nuclear power, it has in recent years become central to US strategic policymaking. What explains this shift? How is the US-China strategic nuclear relationship evolving? What role do other states play in shaping it? To address these questions, the authors of US-China Nuclear Relations examine a series of strategic triangles involving China, the US, and one or more key third actors (among them, Australia, India, Iran, Japan, North Korea, Pakistan, Russia, South Korea, and Taiwan). Their work also critically highlights the challenges and opportunities facing Washington and Beijing in this increasingly complex security arena.
