I am going to answer that question by highlighting the progress that has been made in development, in the context of various statements of principle, including the Paris Declaration on Aid Effectiveness. That highlights your exact question about coordination between donors specifically in the area of development.
But I feel that the lesson is much wider, as you explained. There is an even more fundamental request for, and need for, coordination. I feel that progress has been made in this area, but, as you said, it remains very difficult because of the number of parties involved. This is still a work in progress.
