Is G-20 economic summit helpful to global economy?

Tweet

Last weekend's financial summit included leaders of G-8 club and fast-rising nations such as China, Brazil and India, but they did not give any anticipated remedies for downturn, such as interest rate cuts. After that, Oil price slides towards $56. In my opinion, G-20 meeting fails to encourage us. We can not expect the global financial crisis will end soon. What is your opinion?
