Long March 10 (the 5m one in the article) isn't a Starship/Super Heavy competitor, it's a Falcon Heavy competitor. I.e. it's only barely considered a super-heavy and depending on the reuse penalties, it might only be one if it's launched as expendable. I'm guessing most of the specs on Wikipedia are very out of date so it's hard to tell exactly.
They'll probably go through the same process of getting the core and boosters reusable but not bothering with the second stage and just push Long March 9 development instead. Obviously they have to walk before they can run but at this rate they're still about ~8-10 years behind.
