Three questions about our US Team's recent trip to China: 1)Have any other countries ever come to us in delegation form asking us to make material changes to our currency? 2)Why don't they call it "devaluing the US Dollar" rather than asking China to "raise the value of their currency" Means the same thing in the end. 3)Are the head of the Treasury and the Head of the Fed supposed to be traveling together? Isn't there any kind of Chinese (pardon the pun) Wall there?
