Over the last decade, cities have gained increasing prominence on the world stage. Simon Curtis and Michele Acuto show how and why cities are increasingly flexing their economic and political muscles, and discuss some of the constraints cities face in developing their own foreign policies, as well as the differences between city-based diplomatic activity and traditional state foreign policy. Finally, they discuss the significance of city diplomacy trends for thinking about the international system.
