By eliminating the U.S. dollar from transactions with third-party nations like Australia and Brazil, China is doing exactly what the U.S. has been asking them to do for several years now. One of the long-term criticisms of China among posters right here on this website has been China's policy of deliberately undervaluing its currency by pegging it to the U.S. dollar at a fixed (artificially low) rate.
Guess what, folks ... by eliminating the U.S. dollar from their third-party transactions, China effectively isn't pegging its currency to ours anymore.
I hope you are right.
