... perfectly suited to link China's smaller cities, but not direct connections to it's major cities.

Maybe driven more by environmental reasons (arguably fewer emissions than plane travel) rather than economic reasons (besides job creation, etc).

For even half full inter-city trains I don't think there's any doubt about which is more energy efficient. Trains will tend to win by about an order of magnitude. Planes aren't any worse than cars containing a single person, though.
