ABSTRACT
Air Defense Identification Zone (ADIZ) is an identification zone of civil or military aircraft with attempt to fly from the outside of national flight zone of a state into the flight zone of the state that implements ADIZ. The legal basis of ADIZ determination is that a nation possesses the right to assign certain conditions for an aircraft that is about to enter the territory of a state. State practice is also a factor in the development of this zone.
People’s Republic of China (PRC) assigns Air Defense Identification Zone in East China Sea, of which the zone overlaps with the Japan’s ADIZ including the Diaoyu/Senkaku Island of which China is in a dispute with Japan.
PRC regulates that :
1. An aircraft entering ADIZ is supposed to report the flight information to the authority of PRC even when the aircraft is not headed to national air zone of PRC.
2. PRC will implement defensive emergency measure to respond uncooperative aircraft in identification.
The practice of states that has determined ADIZ shows difference with
the ADIZ of PRC, one of which can be seen in USA’s ADIZ regulation. USA
