The report also noted a growth divergence between advanced and developing economies, adding it expects " a more gradual pickup than was forecast in the April 2015 WEO" among advanced economies, while growth in emerging markets is expected to slow down.  "The unexpected weakness in North America, which accounts for the lion's share of the growth forecast revision in advanced economies, is likely to prove a temporary setback."

Regarding the slower growth in emerging markets and developing economies, the IMF stated:  "The slowdown reflects the dampening impact of lower commodity prices and tighter external financial conditions—particularly in Latin America and oil exporters, the rebalancing in China, and structural bottlenecks, as well as economic distress related to geopolitical factors—particularly in the Commonwealth of Independent States and some countries in the Middle East and North Africa."  Olivier Blanchard, the IMF's chief economist, said in prepared remarks that, while the IMF left its 2015 forecast for China unchanged at 6.8 percent, it did with greater uncertainty.  "The puncture of what had clearly become a stock market bubble may have some limited effect on spending. But, for the moment, the slowdown in growth is primarily led by a slowdown in real estate investment, a development we see as basically desirable," he said, adding that the IMF expects China's growth to slow down to 6.3 percent next year and to 6 percent in 2017.

"As dramatic as the events in Greece are, Greece accounts for less than two percent of the euro zone GDP, and less than one half of one percent of world GDP," he said. "There is little question that Greece is suffering and may suffer even more under the scenario of a disorderly exit from the euro zone. But the effects on the rest of the world economy are likely to be limited."
The IMF trimmed down its global economic growth for 2015 from 3.5 percent to 3.3 percent on Thursday.
