In this article the author evaluates the achievements of the Group of Three (G-3) in four distinct periods. The first period was characterized by a dynamic of political concertation that sought to reestablish political stability in Central America. Starting in 1990, a second stage of institutionalization was begun. The third period was characterized by thefailure of the G-3 to consolídate itself and the non-signing of previous commercial agreements. In consequence, the fourth stage, corresponding to 2000, has been characterized by efforts to reactívate the organization and to incorpórate policies of political concertation, international cooperation and economic exchange.
