The global economic recovery continues to advance, but Europe's debt crisis has created new hurdles on the road to sustainable medium term growth, cautions the World Bank's latest Global Economic Prospects 2010 released on Wednesday. The World Bank projects global GDP to expand between 2.9% and 3.3% in 2010 and 2 011, strengthening to between 3.2% and 3.5% in 2012, reversing the 2.1% decline in 2009.
