After all, in a world comprising nation states, there is no natural constituency for the global economy. There are bound to be differences when the agenda is so broad and country level compulsions are seen to be clashing with global interests.
What is important is that we are able to resolve these differences with the realization that in a globalizing world, no country can be an “island”. What happens anywhere affects economies everywhere. Global financial stability is a global public good, and there can be no more an effective forum than the G 20 to steer the world towards globally optimal solutions.
