“Speculation has gathered speed over the last year, since the tumbling dollar has threatened to weaken China’s buying power”
China will do it’s buying in the US.
Or, you might say, China will do it’s buying “of” the US.
China wants to INCREASE it's wealth but not through the dollar. They will invest in what they see as SAFER INVESTMENTS. The U.S. under Obama is less and less appealing to them so they are diversifying. It's truly hard to believe that China, a supposedly “communist” country is more capitalistic than we are.
