G20 policymakers are agreed that it is too early to pull the plug on economic life-support packages as the global recovery is still fragile, said British finance minister Alistair Darling.

The crisis the world went through is just an appetizer for a future one because the weaknesses that created it have not been addressed, Marc Faber, author and publisher of the Gloom, Doom and Boom Report, told CNBC Friday.

The G8 nations will announce Friday that they will no longer meet separately without the entire G20.

U.S. Treasury Secretary Timothy Geithner says he is seeing encouraging signs of a global economic rebound, but the world still has a way to go to emerge from the severe recession.
