US President Barack Obama has fulfilled one key promise of his election campaign - affordable healthcare for the uninsured.

Healthcare issues have long troubled the superpower - even today 46 million of its citizens, or more than one eighths of its population, are out of its health insurance ambit.

China too is beset by some of the problems faced by the US healthcare system, such as high costs, low efficiency, and lack of justice in implementation.
