I'm trying to grasp the concept of why China is keeping their Yuan devalued while buying a ton of Treasuries. It seems that by keeping the Yuan devalued, China keeps the momentum on its export industry going. But, doesn't this negatively affect China's purchasing power? I'm sure some of the members here can enlighten me on this subject. Also, are there two sides to this (as far as debating how this affects the U.S.)????? Thanks in advance!
