This is the first global crisis that doesn't start in poor countries and it was caused by the rich countries. So it's necessary to take advantage of this crisis - the financial system has to be regulated. It's necessary that the central banks in the world should control a little bit the banks' financing, because they cannot bypass a certain range of leverage. And I believe that there's no other - more any reason for a G-8 group or any other "G." I believe that we should guarantee that the G-20 should be now an important forum to discuss the major economic issues of the world.
