Experts say if there were to be a war to happen, it would first begin based on exchange rates. Dominic Strauss-Kahn, head of IMF said, "“There is clearly the idea beginning to circulate that currencies can be used as a policy weapon. Translated into action, such an idea would represent a very serious risk to the global recovery. Any such approach would have a negative and very damaging impact in the long run.”
China also has the most possession of dollars in the world. If China were too fall, than USA and the world would have to face another world economic crisis. When Lehman Brothers were bankrupt, Asian powers played a big part in recovering the world economy back to where it should be. This is because of the different system Western and Eastern powers have. The economy of most Western powers are based on financial business while the economy of most Eastern powers are based on export business. As soon as Lehman brothers got bankrupt, major banks of the USA fell apart, but because of Asia, slowly Eastern powers are recovering to their normal state. Both countries need each other. Through fixed exchange rates china has been able to maintain a prosperous economy.
"Both countries need each other economically. Through this I think we can see that exchange rates through the free market has some major flaws, we couldn't have seen before. If China were to change their policy, than USA and the world will have to change their policies equal to the sacrifice China would make in changing their policy. The economic system needs reform. The gains of the free market aren't perfectly equal to all countries. Countries like Korea face a hard time when it comes to fighting exchange rates."
