Meanwhile, IMF Managing Director Christine Lagarde warned that the pace of the global economic recovery remained a concern.
"Certainly the global economy has stabilised since the onset of the financial crisis, but the recovery is too weak for comfort," Lagarde said in Washington. "Moreover, unless countries come together to take the right kind of policy measures, we could be facing years of slow and sub-par growth-well below the solid, sustainable growth that is needed to create enough jobs and improve living standards into the future."
"Recovery is taking hold but is too slow and it faces several obstacles along the road," Lagarde said. "Bold policy steps can overcome these obstacles and take the global economy to the next level of more rapid and sustainable growth."
Among key obstacles are geopolitical tensions, notably the Ukraine crisis, she said.
"The situation in Ukraine is one which, if not well managed, could have broader spillover implications," according to Lagarde.
