The International Monetary Fund says worldwide economic growth is expected to recover to 2.5% in 2010.
An earlier estimate by the agency was for almost 2% growth next year, with the increase expected to be led by India and China.
But the IMF still expects the global economy to contract 1.4% this year.
While the global economy is beginning to pull out of a recession, it says stabilisation is uneven and the recovery is expected to be sluggish.
The forecast came as a G8 summit began on Wednesday in Italy.
A draft declaration circulating at the summit said: "While there are signs of stabilisation, including recovery in stock markets ... the situation remains uncertain and significant risks remain to economic and financial stability."
