The International Monetary Fund says the global economic recovery is gathering strength, but faces risks particularly from high oil prices and unemployment.
Among the challenges it lists are rising oil prices, unrest in the Middle East, continued inflation in China and debt problems in Europe.
In a new forecast, the IMF says the global economy should grow by 4.4% in 2011, the same figure given in January.
It said the recovery has solidified, but unemployment remains high.
The IMF says developing countries are leading the recovery, though inflation is a big threat.
However, it says that the challenge for many emerging and some developing economies is to ensure that present boom-like conditions do not develop into overheating over the coming year.
If China were to suffer a slowdown, it would hurt the entire region, the IMF said.
