Goldman Sachs Chairman and CEO Lloyd Blankfein said Thursday that "this could very well be the Chinese century" and that the Asian giant's economy will eventually overtake the U.S., CNBC reported. Blankfein made the comments at the DealBook Conference in New York City, which focuses on issues emerging in an interconnected, global economy. He said the big question is whether the U.S. will grow 2.75 percent or 3.75 percent. In China, the range is 4 percent to 9 percent.
