As explained, the price level or the cost of manufacture in China, the exporting country, is completely irrelevant as their local price/cost of manufacturer is artificially propped up by illegal state subsidies or other anti-market tactics to cripple foreign competition past 15 years. Again, China is a non-market-economy.

In those cases, trade regulators can use "undistorted" prices without gov't interference or use a market price in a similarly situated 3rd country as benchmark.
