The US (who declared to the world that its B52 bombers were unarmed), Australia, South Korea do not matter, according to the editorial in the English language paper Global Times by China's People's Daily.

Japan prime target of ADIZ tussle
Japan has been giving fierce reaction to China's demarcation of the East China Sea Air Defense Identification Zone (ADIZ).
Japanese Minister of Defense Itsunori Onodera has made malicious remarks almost daily since last Saturday when the zone was set up. Perhaps that just proves a folk saying: The more guilty one feels, the more unscrupulous he will be.
Apart from Japan, the US and Australia have also rebuked Beijing for its new air defense rules with provocative remarks or actions, and even South Korea's foreign ministry expressed formal regrets over the ADIZ.
Nonetheless, all the criticism and provocation will not pose a real challenge for the newly created ADIZ. It is a fact that China has already established its ADIZ over the East China Sea.
Maybe an imminent conflict will be waged between China and Japan. As a staunch supporter of Tokyo, Washington is expected to refrain from confronting Beijing directly in the East China Sea, at least for now. Canberra and Seoul just chimed in.
The Chinese government is supposed to remain resolute in its strategies while taking flexible and resilient measures to cope with unexpected accidents.
If the US does not go too far, we will not target it in safeguarding our air defense zone. What we should do at present is to firmly counter provocative actions from Japan. Australia, having no real conflict with China now, can be ignored at the moment.
Seoul understands it is not the target of China's ADIZ, plus it has tensions with Japan right now, therefore, China has no need to change its actions toward South Korea.
We should carry out timely countermeasures without hesitation against Japan when it challenges China's newly-declared ADIZ. If Tokyo flies its aircraft over the zone, we will be bound to send our plane to its ADIZ.
If the trend continues, there will likely be frictions and confrontations and even tension in the air like in the Cold War era between the US and the Soviet Union. It is therefore an urgent task for China to further train its air force to make full preparation for potential conflicts.
We are willing to engage in a protracted confrontation with Japan. Our ultimate goal is to beat its willpower and ambition to instigate strategic confrontation against China.
Though Beijing has encountered difficulties in the nascent stage of the ADIZ, Chinese authorities appear calm in the wake of all the provocations.
The Chinese nation is heading towards peace and prosperity with peace-loving people.
Turbulence over the Diaoyu Islands and the East China Sea Air Defense Identification Zone will in no way alter China's overall architecture.
Fierce reaction? The US, staunch supporter of Tokyo, is to refrain from confronting Beijing?
What they are saying doesn't make much sense, but I suppose it is a good match for the equally incomprehensible Abe administration.
BBC reports (11/29/2013) that China scrambled fighter jets to monitor Japanese fighter jets and the US surveillance planes entering, as far as Japan and the US know, their ADIZ over Senkaku Islands.
