"We must strengthen cooperation among the world's financial authorities," he added, and "move forward with other significant reforms to make the IMF (International Monetary Fund) and World Bank more transparent, accountable, and effective."

Moreover, the president attached much attention to the importance of free market capitalism by saying that "the long-term solution to today's problems is sustained economic growth. And the surest path to that growth is free markets."

The G-20 Summit is to be convened for the global economic crisis. Leaders from Group 8, the European Union and major developing countries will be present at the meeting.
