And yes it does show china can build things, but it also highlights the different calculus of a single party state. They can force people & the state to buy uncompetitive nuclear power (under the banner of energy stability) and not worry about being voted out.
You actually have to build out intermittent renewables much faster than nuclear even for comparable generating capacity due to the much shorter lifetime of the equipment. See Little's Law

China recently signed up to the COP28 pledge to triple nuclear generation. In the same time period, worldwide electricity generation is predicted to rise by 50-100%, so the nuclear share will grow by 50% - 100%.

But chinese nuclear is built faster and cheaper vs our units even during messmer in france. So their price guarantee is lower too. Probably similar to what distributed solar got there of 0.4y/kwh in the past. Albeit subsidies for solar were cut last year to stimulate a healthier growth
China doesn't have free market in the way we have it anyway. It wasn't valid even for solar
Anyway it doesn’t matter, we’re quibbling minor semantics, when I think we agree on the main point - what happens in state run china is in no way representative of what’s possible in a free market economy.
