The global economic recovery has strengthened, with a revised GDP forecast of 4% for 2011 and 2012, though this indicates a slowdown from the previous year's growth of 4.7%. Key challenges include Japan's disaster, political instability in the Middle East, rising commodity prices, and a debt crisis in advanced economies, requiring careful economic policy management. Emerging markets are expected to remain growth drivers, but tighter fiscal policies in developed nations may hinder overall growth prospects.
