I find it rather interesting to play, you can't really trade with anyone to get sorely needed steel, you can't faction with anyone besides your puppets, although you get a lot of nice benefits with the fifth empire spirit, and a cool flag and name.
Anyhow, you get a focus that let's you declare war against all existing chinas, guangxhi has steel and a lot of factories, but is a bitch to invade even as republic of china, and you're portugal and you only got a single tile port that needs to be upgraded to be of any use. I guess you could naval invade from it but even then logistics will be an issue. I guess hainan would be useful to annex as a big fortified port for further invasions of asia, but puppet the rest of guangxhi. Then there's yunnan to your left, not much resources, hard to invade since it's like one tile gap between em. To the north is china which actually can be invaded if you have done the colonial manpower focuses and if you got enough factories, or you could help Japan and carve out your own little fiefdom there, but i'd rather have the whole thing puppet aside from a few concession cities like hong kong, that strip japan owns and taiwan for further dominance of the sea there.
You could also grab galicia from spain and gibraltar and puppet the rest and make a morocco puppet when you take over france.
