I wonder if you could sell them on some of the darker Cyberpunk stuff (darker theme-wise, rather that the metal monster gore shit that Japanese cyberpunk went with), where it's a shitty world and even the "good guys" are just a slightly lighter shade of grey?
Anyway, cyberpunk India and Korea (ignoring for a moment , who has an excellent point, in the China is both the future, and cyberpunk as fuck), well I've seen India done before:
River of Gods is set in mostly peaceful, if balkanised, India (though the companion Cyberabad Days has some short story with a war, including a fun take on "cool teenagers piloting giant robots" anime thing), and Netrunner has the Mumbad cycle, set in an Indian megacity stretching from Mumbai to Ahmedabad, pic related.
India has a long history of at least certain groups being very scholarly, and they have a China-like ability to rely on numbers for high end talent thanks to their enormous population.
Korea seems to be pretty ignored in general, especially after their bubble kinda burst, but they're still not small, and they're pretty cyberpunk - if anywhere fits the Gibson everyone-gets-surgery-for-fashion thing it'd be Korea, everyone knows how mad they are about e-sport, and at least one of their members of parliament is a Hyundai exec.
And speaking of Hyundai, it was a Chaebol (the Korean version of a Zaibatsu) and even after being split into mere allied companies on the death of its founder is still enormous. It is one of only 2 car companies (the other being Tata, which is Indian) to be vertically integrated - meaning it owns the whole process from making steel to selling to the man in the street. And they also sell mining equipment, even if they don't mine themselves.
While it's not especially cyberpunk, I feel it should be pointed out that in the 80s, the Indian Navy's Marine Commando Force were equipped with crossbows supplied with cyanide-tipped bolts. Because that's cool as fuck.
