No, China imposes rather large tariffs on external goods to force internal consumption. That's beyond a bunch of other measures that prevent foreigners from starting businesses or owning property.

Of course as other comments in the thread have pointed out: a much smarter way to roll out tariffs to encourage domestic manufacturing is by slowing ramping them up to give industry time to react.

My lathe was $3400. A week later the price is now $4000 thanks to tariffs. There are no domestic manufacturers left and banks/Wall Street aren't going to finance someone spinning up a machine tools company. The difference in price isn't enough to erase China's excessive subsidies to their industry combined with their lower labor pay rates so even if someone did try to compete they still couldn't match $4000. My best guess is more like $6-7k. In the end all the tariffs are doing is making it more difficult to get into machining.

If idiots and sycophants weren't steering the ship the US would have a state-run investment bank that partnered with private capital to offer investments to anyone who wanted to start a business. Frankly I think there is lots of opportunity in various spaces like machine tools to make innovative products at all scales from the small hobbyist to big industrial shops. It won't be a 1000x return though so no one cares.
