What is currency manipulation, anyhow?

Currency manipulation could be the next international skirmish, if the G-20 cannot resolve the issue. China has long been known as the emperors of devalued currencies. This gives them a substantial advantage in the trade market, as their goods will be cheaper internationally. The main problem is that many developed countries believe that China's current 10.5% growth will fade maybe too quickly for the balance of the world economy. Yet, some people the United States in particular is being hypocritical. The FED's recent investment in the U.S. economy totaling $600 billion is a direct method of decreasing the dollar. China and Britain are responding to China's tactics by devaluing their respective currency as well. There will be trouble afoot at the G-20 meetings.
