Hours before the arrival of US vice-president, Joe Biden in Beijing, China lashed out at Japan, alleging that Tokyo was continuously causing provocation and affecting peace and stability in the region.
In a late night statement, the defence ministry said Japan had established an Air Defence Identification Zone (AIDZ) as early as 1969 and later expanded and extended its scope to some 130 km from the Chinese coastline, covering most of the air space over the East China Sea.
"Since September 2012, Japan has been making trouble over territorial disputes, staging a farce by announcing that it would 'purchase' the Diaoyu Islands, frequently sending vessels and planes to disturb Chinese ships and planes in normal exercises or training, openly making provocative remarks such as shooting down Chinese drones…," the statement said.
It said that Japan was attempting to play the "so-called China threat" to escalate regional tension, adding that it was an excuse to revise its current Constitution and expand its military.
The ministry indicated that the establishment of Chinese ADIZ was to counter Japan's intentions to trigger instability in east China.
"China has to take necessary reactions. A very few countries must earnestly reflect on their actions and correct their wrong remarks and wrongdoings…
Other parties should not be incited, or send wrong signals to make a very few countries go further on the wrong track, which will follow the same old disastrous road and undermine regional and world peace," the statement said.
An ADIZ, the ministry said, was essentially different from territorial airspace or no-fly zones.
"It is not a country's territorial airspace but an international airspace demarcated outside the territorial airspace for the purpose of identification and early warning; it is not a no-fly zone, and will not affect the freedom of over flight, based on international laws, of other countries' aircraft," the defence ministry said.
