Aren't these the same Chinese cars whose engine life is several times shorter than that of German cars, and whose prices are only 1.5 times lower? Aren't these the same ones where the bodies are made of foil, not durable metal, and the suspension sucks? And where do these bodies, like the wiring, start to rot after 2-3 years? It was about the same with Japanese cars 25-30 years ago - they were significantly inferior in quality to German ones. As soon as the quality levels out, the prices become the same, unless someone gives them subsidies. Guess in 3 tries who gives subsidies to Chinese manufacturers? Taxpayers at the instigation of the CPC... And this is not a market economy. And therefore, increased duties on their products are justified. After all, this is not fair market competition, where they will lose miserably even with a much cheaper labor force, because their products are of lower quality.
The situation is roughly the same with the IT sector now - where there was advanced Western equipment and merciless exploitation of cheap Asian workers, the Chinese temporarily won in "market" conditions. As soon as they were blocked from accessing Western technologies, they immediately deflated like a punctured balloon. After all, the balloon has no strong shell, i.e. a wide layer of talented people capable of making local equipment using the most advanced, global, technologies.
If there are no subsidies (but this is now a sad feature and the US - a slippery slope to socialism), then those who were ahead and did not forget about supporting and developing advanced human capital - the main resource of any country - win. Without it - there is nothing.
