Then why is China building 30 new reactors on top of the 60 they already have, if it's not competitive?

The answer is usually more about how China can actually build things, not that nuclear isn't economically feasible.
China can build ten reactors for the cost of Germany running the appeals, environmental studies and neighborhood consultations for one
And yet, even with their buildout the nuclear share of electricity is projected to decline y/y. Because renewables are cheaper.
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.
The way China building new reactor is not typical.
Most of the countries builds _one_ type of reactor, or a group of similar type of reactor. This help reduce the cost of training and certification.
China, otoh, tries to _diversify_ their reactor type.
If you look closely on how China treat techs, they have been doing the same for all tech for past 15+ years. They are strategically growing their tech profile.
