Were these other zones set-up unilaterally with minimal notice and overlapping other countries equivalent zones?
If the zones had been set-up in a diplomatically sensible way then perhaps there would not be such a reaction and they may have been taken seriously rather than ignored.

The actions of the CCP do not seem to take into account the responsibilities that should go along with being a burgeoning super-power.
