A Little History (and Geography)
Before you read the explanation below, take a look at the map. The blue area is Japan’s ADIZ. Japan enlarged it again in May of this year, taking up more of the sea that China has controlled since the 3rd. century AD…
The Japanese seized the Senkakus from China in its defeat of the Chinese military in the first Sino-Japanese war of 1894-5.
The Potsdam Declaration (Declaration Defining Terms for Japanese Surrender) of 1945 set the terms of Japan’s unconditional surrender. It was issued jointly by the Allied powers – the US, Britain, and China (the Nationalist or Kuomintang government); and the Soviet Union later “adhered to” the declaration. The Japanese government explicitly accepted it.
The declaration said that Japan should retain no overseas territories.
China was excluded from a later conference issued the Treaty of San Francisco in 1951, and hundreds of islands south of Japan were ceded to Japan, comprising the whole of Okinawa prefecture, including the Senkaku.
Ten years ago, Japan extended its “ID Zone” to within 130 km of China’s coast, and recently has taken administrative control of the Senkakus.
Last May (2013), Japan again extended its ADIZ further into Chinese waters.
It is clear from the image at right that Japan’s ADIZ is vastly larger than China’s, and that it – probably deliberately – extends into waters that have been China’s for millennia. Japan is dooming any hope of an economic recovery with this silly reaction. Their exports to China are already down 10% since they started the Diaoyu squabble, and this will make patriotic Chinese even less enthusiastic about trading with a country that is making itself an enemy.
