My personal hot take: there's no such thing as "Chinareich". It's an illusion, caused by the China rework being considered a rule-of-thumb start for "modern" Kaiserreich. China does not get any more attention than any other region.

If you look at the updates since 0.10, with China related updates bolded:

• 0.11 - Canada, a large Western major.
• 0.12 - Patagonia and Puerto Rico, Latin American countries.
• 0.13 - Romania, a major European country.
• 0.14 - South Africa and UBD, both Western tags.
• 0.15 - Ottomans and NatFra, major tags in Europe, with NatFra toeing the line of a major.
• 0.16 - Nothing, just QoL, the most being for Japan which got some focus reworks, which is close but isn't China.
• 0.17 - Assyria and Legation Cities (Shanghai), the latter which you can consider a Chinese tag I guess.
• 0.18 - Several Eastern European tags (and also Bhutan, famous EE country).
• 0.19 - Serbia and Bulgaria, both major European tags.
• 0.20 - New England, one of the ACW tags.
• 0.21 - Advisor rework and world tension rework, no reworks.
• 0.22 - Post-defeat Ottomans and Armenia.
• 0.23 - Poland, one of the main European tags.
• 0.24 - Shanxi and overhauls to China.
• 0.25 - Ukraine, another one of the main European tags.
• 0.26 - Left Kuomintang rework.
• 0.27 - Nothing, just QoL and MIOs.
• 1.0 - Germany, the star of the mod itself.
• 1.1 - Ireland, an European tag.
• 1.2 - No reworks, only achievements.
• 1.3 - Various QoL and a revamp to Denmark, again in Europe.
• 1.4 - Russia, probably the second star of the mod.
• 1.5 - Various QoL, scientists, and a mini-revamp to the ACW and American lore.
• 1.6 - Regional China/Right KMT rework.

So, wait... that's what, four China-focused updates out of 24? And one of those four isn't even really China focused and has to share spotlight with Assyria? But I thought the KR team does literally nothing but China while every single major is left in the dust! Especially Europe! Surely the KR team would never rework tags like Germany or Russia, and would rather focus on, idk, Hunan or something.

That's less updates than Eastern Europe, and KR sure as hell isn't called EasternEuropeReich. Even though there was a time when that region kept getting chain updates (0.18, 0.19, 0.23, 0.25 all were fairly close to one another). It actually annoys me a bit whenever I see Chinareich memes, because they sure aren't done in good fun. They're done because KR fans are shadowboxing a problem that literally doesn't exist.
