2009 witnessed negative growth of world real output for the first time since the Second World War. Now the global financial crisis is under controlled，and the world economy has shown some signs of bottoming out. But it is still too early to assert that the world economy has entered the stage of solid and sustainable recovery，for the major economic indicators give very different signals about the current situation and the future trend of the global economy，while many deep-rooted problems will not be fully resolved in the short or medium term. The world economy will probably grow at a low speed in 2010，though there may lie some risks of another downturn.
