Having said the above, it is advisable not to paint a group portrait with too broad a brush. Oversimplification or overgeneralization only leads to distortion of the resulting picture. Without further details about your particular encounter with one Chinese hiring manager's no-show at the appointed time, it is hard to say whether any mitigating circumstances existed that would have lessened the deplorableness of his seemingly unprofessional behavior as you described.
