"Japan is not depended on Chinese economy too?"

No, Japan is NOT among the international-trade-dependent countries, especially whose portion of the amount of the export to China accounts for just less than 3 percent, while that of the investment into it a little more than 1 percent.

According to the statistics of the World Bank, the degree of dependence (the ratio of the total amount of export and import to GDP) of Japan is 28.58% (2011), which means that Japan is the 175th among 180 countries.

Its dependence on export is 14.02%, which means 148th among 185 countries.

Japan is not among the trade-dependent countries such as Hongkong 400% and Singapore 300%.

FYI, The average of the world countries is 52%.

"America is not depended on Chinese economic situation?"

No. America also is completely independent country economically. The degree of dependence of the US on the trade is 7.5-10.8%.

"In this world, in economic terms specifically, no countries can stand without another countries, but a delusional you can think that his country is the greatest and the center of everything, the center of Asia, and dont need the help of any other countries.............. not."

Stupid. I have never denied that no counties can stand without another countries and never said that my country is the greatest and the center of everything, the center of Asia, and does not need the help of any other countries.

Listen, you daydreamer, I say to you, "Every country including Japan needs another country, while Japan does not need China always in order to economically survive, because we have many other countries that can manufacture our goods at their plants. If China continues to be arrogant like today and take an anti-Japanese policy, we will move our plants to other countries such as SE Asian ones. That's it."
