Economic growth led by the United States and China is accelerating, amplifying the risks of an uneven global recovery, the head of the IMF said Tuesday. IMF Chief Kristalina Georgieva said the body sees faster growth in 2021 compared with earlier projections, but warned of increasing signs of a "multi-speed recovery" in an address ahead of the body's annual spring meeting co-hosted with the World Bank. One concern is that an unsynchronized global recovery could lead to higher interest rates in richer economies, sparking capital flight from poorer nations, she said. Dt-jmb/wat
