Finance ministers from the Group of 20 industrialized and developing economies are meeting near London on Saturday to discuss a common approach on how to tackle the global economic crisis. The London G-20 summit on April 2 was initially going to focus on financial markets and regulation, but the deepening crisis around the world has highlighted the need for a broader economic package. This plan includes everything from stimulus packages to uneven interest rates, said Mark Malloch-Brown, British Prime Minister Gordon Brown’s envoy to the summit.
