.....You do realize that the cultures that Raya is inspired by aren't East Asian, right? It's inspired by Southeast Asia which is a completely different region from China, Japan, Korea, etc. and SE Asians (both those who live in America and especially those born and raised in the region) will get pissed if you try to imply otherwise. Southeast Asia is comprised of nations like Vietnam, Cambodia, Thailand, Malaysia, Indonesia, Bali, the Philippines, you get the picture.
For as stupid and half-assed as Disney's been in the costuming department (and doubtlessly in many other departments, knowing them) there are some pretty dead giveaways to the fact that the movie takes inspiration from Southeast Asia. This is primarily in the architecture of different structures seen in the trailers, the forms of martial arts used by the characters, the landscape of the setting, and the fact that her weird little armadillo steed thing is literally named Tuk Tuk, which is a pretty widely used term down there that means "rickshaw," a very common vehicle in the region.
Just because something is Asian doesn't automatically make it Chinese. That's ironically a mentality that would make China extremely happy, and I wish people would break out of it more.
Frankly, I was basing my assumption of this being yet another attempt to appeal to the chinese market mainly on how much Disney has been sucking chinese microdick more and more in the past decade.
What I said still stands, though: They don't use legitimate, real clothes from irl nation's histories to avoid pissing off the political beehive that is Asia as a whole. They don't go out too blatantly with "Tribe x is our version of nation y" cause that could piss off people a whole lot... And it doesn't really matter whether these tribes are stand-ins for Korea/Japan/etc. or Indonesia/Vietnam/etc. If anything, it feeds into what I am saying even more:
The South China Sea is a hotly contested region with many nations laying claim to the same stretch of ocean, with china becoming increasingly aggressive with their demands and their hostile activity. All these nations used to be vassal states in the periphery of the former chinese empire to some degree, paying homage (and taxes/tribute) to the chinese emperor. Now china very aggressively wants to reclaim ever growing parts of that region for their nation and become the centre of political and economic power, with all other nations following their demands and orders (like in the good old times).
The basic plot of this movie seems to be:
Dragons protected the unified lands from evil and some blue crystal ball was somehow tied into this.
Something happened, the multiple tribes started to argue and broke the ball, almost all dragons turned to stone and the tribes split up, the crystal got scattered.
The tribes now hate/distrust each other and squabble amongst themselves, while a growing threat from the outside looms.
MC (Raya?) goes out to find
the Dragonballs and to summon Shenlong a Dragon to summon the Dragonball.
Presumed end: The multiple tribes find common ground and overwhelm the threat together under the leadership of the MC's tribe.
All this can be tied very easily into pandering to china by making it about all other tribes (ie: nations) become united under one tribe's wings. If they want to be super blatant with it, the Dragonball/Dragons could just be a metaphor for the chinese empire and their vassal states and how everything went to shit, once the chinese empire broke down... and lo and behold, the chinese empire broke down when european nations started throwing their weight around in Asia.
It's also just very telling that the MC's tribe is called the Heart of the Dragon - heart being synonymous with "something in the middle" but also with "essence" and "soul". I doubt I have to go into detail how that ties into chinese self-perception. There's also the thing that the azure dragon used to be a symbol of china itself.
I still fully expect the BBEG in this movie to be a metaphor for foreigners/europeans and I expect there being more or less subtle hints at the blue dragonball being a metaphor for chinese influence or identity.
Maybe I'm just way too cynical and all this is reaching, but with the Disney "Thanks for allowing us to film here, Xinjiang Bureau of Administration and Concentration Camp Management" Company, you never know. They desperately crave Yuan bills and there is not a single chinaman knob unslobered by Disney execs in an attempt to get to them.
I'm actually going to salute Disney if at some point they compare the united tribes in this movie with the words "brotherhood", "siblings" or something along those lines.
It would be a rather subtle way to get an implied hierarchy past Western audiences' perception.
