"We are now living in a G-Zero world, one in which no single country or bloc of countries has the political and economic leverage - or the will - to drive a truly international agenda. The result will be intensified conflict on the international stage over vitally important issue, such international macroeconomic coordination, financial regulatory reform, trade policy, and climate change.This new order has far-reaching implications... waiting for the current era of political end economic uncertain to pass. Many of them can expect an extended wait."
