China, an economic threat

[opebo]

I still don't see how they can buy more dollars than we can print.  I mean, even if they're just printing renminbi to buy our printed dollars, that's a tie - the creation takes place at the same rate.

Just type 'one trillion dollars' into an account on a computer at the Federal Reserve, and then send buy orders billed to that account out for renminbi.  Voila - cheaper dollar, more expensive renminbi.
