At the close of the last millennium, prominent thinkers projected that the political systems of leading economies would converge during the coming years. Yet, research has shown that China and the United States have developed distinctive institutionalized governance processes (IGPs) to address environmental issues. Can these distinctive processes persist in turbulent times? In reality, the two countries seem to be decoupling in their economic ties and diverging in political pursuit. Under the current circumstances, what can we say about the ability of the two systems to meet emerging environmental challenges of the 21st century? We argue that neither system is likely to experience fundamental change during the foreseeable future. Current developments are highlighting differences between goal‐based governance strategies prominent in China and the rule‐based strategies of the United States. As the urgency of solving transcendent problems like climate change rises and political tensions grow, it is essential to work with divergent systems to address common problems.
