Chinese is afraid America will start dumping war,so they have to lend money to Americ
If American and European don't have enough money to buy Chinese goods in the future,Chinese will be afraid Americans will export too many products that is the same as Chinese products to other countries,and then most of Chinese factories will go bankrupt.
Chinese don't have enough resouces and aren't able to create enough new products to win American and European dumpng wars.American and European dumping wars are more dangerous for Chinese economy now than American and European trade barrier.
They have read the history of Prussia,Japan,Britain,Spain,Russia,13.US.states and France,etc,so they know American and European dumping wars will cause every country's trade barrier.Because they have a too large of population who have to export goods to other countries to buy oil to grow enough foods,they start to think they have to arm themselves to become pirates or neocolonialists.
In their history,Chinese have ever colonized Southeast Asia,Japan,North Asia,Middle East,India,Africa and Middle Asia,so they are not good guys in the past or future.If America becomes weaker in the future,Russian will ally American to stop Chinese military adventure.We are still not sure which side the Indian,German and Japanese are.We know they have own war plans.They have the same problem as Chinese that is their population is too large for their resources,but they are competitors of these Chinese.They will unify each other against Chinese.
Some countries have the same problem as China that is they have too large population for their resources such as Britain,Germany,France,Italy,Israel,Korea,India,Ja pan,Indonesia,Bangladesh and Pakistan,etc.Japanese and Chinese population problem are more serious because they have strong armies and less farmlands.
If world economy,America economy and some other countries' economy become worse and worse,above countries will all be in a big mess.Some of them will have Civil wars,some of them will kill their civilians,some countries will start WW3.Terrible socialists will make a come-back.Also,I am worried if European jobless rate is too high,they will be controlled by socialists in the future.
