Institute Professor FANG Ming said in an interview with Financial Times on April 16 that the quantitative easing policy of the United States would accelerate the recovery of the global economy to some extent, but it was tricky for the world economy to return to the normal track under the pressure of the huge debts of various countries and the quantitative easing monetary policy of developed countries. The recovery of developed countries and emerging markets does not always go together, which might trigger local or even global systemic crises.
