Yang Yujun quotes
On this, there is no need for other countries to gesticulate. Whether or not to or when to set up an air defense identification zone depends on whether there is an aerial threat or the level of aerial threat. It needs many considerations.
An Air Defence Identification Zone is neither territorial airspace, nor a no-fly zone. It's an airspace set up by a country outside its territorial airspace to allow time for early-warning and ensure national air defence. It does not mean an expansion of the territorial airspace.
It is not directed against any specific country or target. It does not affect the freedom of flights over the airspace concerned.
