VIENNA (Reuters) - China's central bank is cautious about the ultra-low interest rates adopted in much of the developed world to stimulate economies, Yi Gang, a Chinese central bank vice governor, said on Tuesday.

"We’re still very cautious on this (zero-interest rate) monetary policy," Yi Gang told a central banking conference in Vienna.

"We have to be very careful and look at the limitations and uncertainty of a zero-interest rate policy, because in China we still have a decent growth rate."
