Continuing CIGI's BRICSAM research, this paper questions whether the size (economic or population) of emerging economies alone is enough to warrant accommodation in the rules and structures of the international system. The global realignment of states following the power vacuum brought on by the end of the Cold War is finally materializing, as a new triangular formation has taken shape: the "first world" club of the OECD; the "second world" of emerging economies; and, a heterogeneous "third world" of the rest. The interplay between and mobility among these groups of states deserves in-depth analysis. The core of this paper observes the economic and social trends of countries in the second tier, and their upwards aspirations towards the top tier of the global architecture. Traced through a variety of indices, the growth of the BRICSAM group of countries (Brazil, Russia, India, China, South Africa, ASEAN-4 and Mexico) is demonstrated to be a powerful force in international economics and political economy. For the inclusion of these states, a change in the key aspects of global economic governance, the international architecture and geopolitics seems inevitable, and with it, new challenges arise for decision makers and scholars alike.
