China is the world's largest electricity producer and installs a lot of generating capacity of all types. For example, China has 29 nuclear reactors with 31 GW of capacity currently under construction:

It shows that strategic investment matters and people are looking at more than a single cost metric. Nuclear is behind today, but that doesn't hold a promise it will remain true into the future unless you stop investing now.
One armed bandit says explore as well as exploit. This delta you cited indicates the pendulum currently is more exploit than explore, but its not a static equation.
chinese nuclear is extremely cost competitive at 2.5bn/unit. They have other reasons, one being the ban on inland expansion fearing of messing up with 2 major rivers that feed the country. Current chinese units are basically borrowed and improved western designs, cap is basically vogtle's ap1000, hualong is a frankenstein of several western designs.
>borrowed and improved western designs
TBH this part seems key, even PRC couldn't operate full western designs reliant on western industrial capacity economically, part of it was simple incompetence of western supply chains (business closures / regulatory drama / sanctions). Nuclear seems viable once you strip out a lot of the politics that makes them uneconomical, hence PRC had to indigenize the designs since once western supply chains enter picture, the schedule goes out the window.
Which leads to a shrinking nuclear share in their grid. 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. And of course to enable their military ambitions.
