The difference is that they're not doing it at the expense of hollowing out their domestic industry. They're supplementing their own industry by building additional industry around the world.

Why do you assume the West? China often expands to other Asian countries. Or pretend to. E.g. after tariffs are applied to China you'll often see a huge increase in intra Asia trade. Followed by different Asian countries heavily increasing their exports. Usually by hiding the true origin (tariffs are applied to the origin, not some transhipment place).

This is what happens with production revolutions. We did the same thing, as did England.

Woulda been funny. Not just for the obvious benefit of having an uprising and potential revolution in Europe, but also to see how genuine those "red millionaires" are about socialism with Chinese characteristics

Free market propaganda has never been applied under equal circumstances. It is rhetoric used by capital to reduce or destroy regulations, labor, national sovereignty, etc. Western industrialized capitalist coubtries built their industry and infrastructure using tariffs to protect it, then turned around and demanded the opposite from other countries so that they would have to buy their products and sell whatever those colonizer countries wanted (at the time, usualky raw materials).

Now that other countries are ascendant, US-based "free market" capital is gladly re-embracing protectionist logic. It has only ever been about maximizing their profits. The "theory" of free markets tails capital, it isn't a science or even a valid line of thought.
