First of all? The reason why Japan wants to seize the Diaoyu Islands? Because he saw the great military value of Diaoyu Island. Geopolitics? Diaoyu Island lies between Taiwan Province Province and Okinawa? On the first island chain in the western Pacific? It is a springboard for the distant sea to enter China, and also a barrier to prevent China's navy from entering and leaving the Pacific Ocean. What if Japan completely controls the sea area? China's navy was not only strangled. It is also an ideal frontier base for attacking China. Do we know what Japan means to China? It can be said that it is a tiny place. And it's distributed in bands? This is why Japan does not have the advantage of strategic depth that China is proud of (the importance of strategic depth can be seen from War of Resistance against Japanese Aggression and China). Once the war comes? Japan is vulnerable to attacks from all directions. By contrast? If Japan takes the Diaoyu Islands? Can expand its strategic depth? And China will reduce the corresponding strategic depth? This is obviously beneficial to Japan? Not good for China. Second? Diaoyu Island has great economic value. From 65438 to 0966, the United Nations Economic Commission for Asia and the Far East explored the seabed resources in eastern China, including Diaoyu Island. Draw a conclusion? The continental shelf of the East China Sea in China is probably one of the richest oil fields in the world? The waters near Diaoyu Island may become "the second Middle East". According to statistics? What are the developed petroleum resources in the world at present? Mainly from Cenozoic and Tertiary? Formed thousands of years ago. Found it in the rocks. Is the seabed of Diaoyu Island a Cenozoic and Tertiary sedimentary basin? It has ideal geological and structural conditions for generating and storing oil. According to the annual estimates of relevant scientists in China? What is the oil reserve in the waters around Diaoyu Island? Billions of tons. And the fishing resources in the waters around Diaoyu Island are also rich? Rich in flying fish and other fish. Besides? There are also rich and precious medicinal materials on Diaoyu Island. So what? The economic value of Diaoyu Island is very noticeable to Japan. Finally, politically, Japan cannot give up the Diaoyu Islands. The ownership of Diaoyu Island has always been controversial? Although we have every reason to prove that Diaoyu Island belongs to China, the Japanese changed their attitude after seeing its great value? Forcibly explain that Diaoyu Island belongs to Japan? And draw it on the domestic map in Japan. Once this behavior starts? He can't give up easily? Because this is no longer a problem that leaders can decide. He must also be responsible for his own people? Carefully consider the international influence. One more thing you can't deny? Does Japan want to transfer domestic contradictions? In fact, isn't China the same? . In recent years. Japanese Prime Minister took office less than a year ago? Without exception? Is regime change a sign of national instability? Japan still has ethnic problems? Many contradictions brought about by the economic crisis and so on. So in the case of unstable Japanese regime? It urgently needs to find something that can distract people? Therefore, Japan is more entangled in the Diaoyu Islands issue. These are the reasons why Japan will spare no effort to seize the Diaoyu Islands from geopolitical theory.
