What you are looking at is my China Playthrough of the PRC that I.. had 'fun' with (used console commands, because I barely understand HOI4 that isn't LARPing as leftists and gaining super weapons lol) This is in The Fire Rises Mod right here, that features cool and weird paths and allows for these fun stuff to happen. What you see is just the beginning btw, because this: 
is what I ended off with before I went to bed. Took me like, 6 hours, honestly, and I need some.. break from HOI4 afterwards, because being this obssessive over moving units around does not make for good creative work, but if you want, I can like... add more screenshots of the Americas, or Europe if you're curious on how that went.
The only thing i hate about the china content in this mod is that you are locked out of the super ML focus path if you don't lose the taiwan war.
I hate how there's barely any interaction between China and Russia (especially the revived USSR) even in the cases where it would make sense to support each other in their respective wars.
True, I remember the timeline like this CPRF (Russia, for now) is elected The Taiwan War (China vs Japan, Taiwan and South Korea) The First European War (RSFSR + other soviet republics vs NATO) The Great Asian War ( EADI - China vs. PDTO - Japan) The Second European War (MTO - USSR vs. Pact of Steel - Germany)
So, there's definitely a lot of interactions that should happen, in both the USSR (if they don't use Chinese Model) and China (especially in my playthrough involving Xi because I didn't deliberately lose my own Taiwan War). When I played as China, there was no focus to help the USSR in any way, it was all my doing, sending lend lease, volunteers etc. As the USSR when I played them, I barely paid attention to China, I just volunteered when I could and since I went down the non-Chinese Model Path, I couldn't get the interactions associated with going 'Deng' (lol).
Yeah more or less my thoughts. To a lesser degree, there's also America's case, when it becomes the UAPCR.
Even though it is partly deindustrialized and wartorn initially, it can become an powerhouse isolated from any serious world threats and an invaluable ally. And there's nothing between it and China or the USSR, not even something BnR related?
Yeah! Though, in my game, the post-civil war tree had missing icons and generally was 'generic' to any APLA winner (i.e. UAPCR, SRA, USSA, and APAP), I think, it was likely unfinished as well, though they could do with a new alliance, it was pretty much unfinished along with the ADS (you know, the UN, communist version) and yeah, the whole BnR or BRICS stuff, I think that's also unfinished.
In general, TFR is a young mod (Just a year old! At Oct. 18, 2024 is their official release!), and if they keep up the good content, they can catch up to maybe Millenium Dawn-type content without it's bloat, especially with the more... chaotic and interesting scenario with the 2ACW, First European War and Taiwan/Great Asian War.
Bruh, I just wanna play like Japan Communism or UK Communism, or heck, give some love to Iran, Saudi Arabia, India & Pakistan, or even like the rest of non-Japan/PRC Asia, the entirety of Africa or the whole of Americas that aren't the US! But.. there are priorities, and as far as I know the Revanchist (PRC) Path was just added, and as far as the teased content are concerned, it's more of just updates to America, Russia and the Koreas.
Until then, I guess like, you can't play as Gaddafi ruling over North Africa just yet.. or any updates to like how certain focuses and events work.. IDK, maybe we can complain at their discord about that, hah.
Ah yeah that's true, but it makes sense because how would the leadership and ideology of the party shift if that same ideology won them the taiwan war? Though I really wished there was a way, maybe civil war? IDK.
