This paper focuses on the clean energy and climate change component of U.S.-China relations. It reviews why the cooperation was so minimal before 2009 and the changes since then. It then analyzes the politics of forging U.S.-China cooperation in the coming months and makes policy recommendations on how best to structure a presidential level bilateral agreement on clean energy cooperation. Finally, it examines the need to re-focus the goals at Copenhagen and articulates how Washington and Beijing can play a critical role in teeing up that meeting for success. -- Intro. (p.1)
