Sure but there's all the US tariffs which artificially increased the prices in the first place. Furthermore there's the inflationary effect of the currency devaluation. China imports lots of raw materials for manufacturing as well as food and energy. So your costs to making that plate are increasing and the wages you pay your workers isn't worth as much as it used to be. Yuan devaluation effectively takes wealth from all Chinese and puts it into the hands of Chinese exporters.
