pay no attention to exchange rates
let differential national "growth " rates rebalance trade
the forex arbitrage must be maintained
"We find that a stronger renminbi would have a relatively small near-term impact
on the U.S. bilateral trade deficit with China and an even more modest impact on the overall U.S. deficit..
......we think that the gap will shrink.... primarily as a consequence of the high rate of economic growth in China"
