Chinese emissions are primarily because of a choice to exploit its thermal coal reserves for power generation instead of going nuclear. Probably was cheaper and faster to go that way - but it was definitely a choice.
As far as I can tell from an American perspective, the US has always done what was cheapest and fastest, and we still do. I sure wouldn’t expect China to do anything different.
China only recently has a 3G reactor design that is 100% Chinese IP. The state-owned enterprise that handles nuclear reactor construction is on the U.S. entity list.
