Impediments to China's economic edge

Former US treasury secretary Hank Paulson thinks some Americans are naïve to assume that the Chinese government can do whatever it wants to grow its economy.

He believes there's more danger in exaggerating China's strength than in underestimating it, but he also concedes that America's economic prowess took a real hit in the eyes of the Chinese at the time of the 2008 crash - when Mr Paulson was running the US Treasury.

He tells the story of how one Chinese official told him at the time that America had been seen as China's teacher but now the teacher didn't look so smart.
