Solar and Nuclear energy are different energy products. China is also bringing on an insane amount of nuclear energy.
China is building a tiny amount of nuclear in comparison to their wind, solar, storage, and HVDC builds. Only something like 50-100GW over thw coming decades. The quantity being built only makes sense as a strategic hedge, not as a primary strategy.
Renewables crash the money making potential of nuclear power. Why should someone buy ~18-24 cents/kWh new built nuclear power excluding backup, transmission costs, taxes, final waste deposit etc. when cheap renewables deliver?

China is barely building nuclear power, in terms of their grid size. It peaked at 4.6% in 2021, now down to 4.3%.
Compared to their renewable buildout the nuclear scheme is a token gesture to keep a nuclear industry alive if it would somehow end up delivering cheap electricity.
In absolute terms, China installs about as much nuclear as the US does solar. So I can only assume you agree with the statement "the US is bringing on an insane amount of solar energy"? Because, once again in absolute terms, the US's solar buildout is trounced by China's. The US is losing the energy race, and nuclear isn't going to save it. The US will run out of fissile material before China runs out of sunlight.
