The advisory they give is the help you are getting from them. It's not like they can send the FBI Hostage Rescue Team or Delta Force to China anyway, even if they wanted to. They might try to get you out in special situations, for example if a friendly country had terrorists taking hostages confined to a small area or if a small and/or weak country tried something and there was no or only a weak travel advisory before the incident, but even then I would not count on it.
