A weak dollar is not that simple, nor is a strong RMB. Our economy is more complex than the chinese economy, but even so the repercussions of a strong and or weak currency aren’t so easily discerned. For instance the US is still the worlds largest manufacturer, just not of clothes or electronics. So a weak dollar seems like it helps us sell our end products, but those end products are in turn made up of constituent parts made in other places. Any gain in end sales tends to be offset by a rise in cost for imports.

Conversely the Chinese make lots of stuff, but have to import most of the basic commodities to produce those things. Therefore the weak currency adds to the cost of production. For example if you think oil is expensive for us, trying being a chinese business. All of your commodities are artificially expensive. In essence the chinese govt is attempting to subsizdize exports with imports.
