Actually China might be potential market, after all girls play house while boys play war, and from what I can tell that is true no matter what culture they are in.
I know that Korea has always viewed China as a very warlike nation and the martial arts are one of the main pillars of Chinese culture, plus they have that whole "All united under Heaven" thing, so while they may have a saying against war they certainly don't practice it. Even if they did, it shouldn't be real road block, after all one of the most significant growth periods in our little hobby here in the US happened just after the "sex not war" people where in full force back in the 60's and 70's, that's when good old Gygax got inspired to do D&D by playing his fantasy war games with friends....
Back on track, the real question for a Chinese market isn't cultural acceptance (if China's national pride is even half as strong as Korea's than yes there will be interest in dynastic minis made in their own country), as it is of disposable income, that may be a real problem.... or not, I have seen second hand GW stuff being sold by Chinese dealers, but I would want to check that thoroughly first, maybe see if there is a built up war gaming community. I know that Japan has a small but thriving tabletop gaming community, Russia had a cheap answer to WH40K in the form of Robo gear and back on the old forum we had some guys from Korea, so a direct from factory approach might not be a bad idea for that part of the world regardless, but I wouldn't know (what is needed is someone with real market research skills and who is knowledgeable about tariffs for that one).
On to a slightly different topic, I have heard of a new mass combat game for 16th century Japan called [url]Daisho[/url], it might have rules for Koreans and Ming, but Chinese, Korean and South East Asian history should have its own game rules, my recommendation on that front is that Watchful I Studio is cooking something up for the miniatures they got kickstarted.
If I where to pick two periods that would be awesome war games it would be Three Kingdoms Korea and post 14-16th century south east Asia (I could even have some rules for Japanese, believe it or not).
As to figures, to my knowledge if you want historic plastic sets of Chinese and Koreans the only scale they are available in currently is 1/72 (I was actually looking at them before I started to buy 28mms), that is also the only scale you will find Ming troops that are sold as Ming to my knowledge. However Perry's Koreans are dressed the same as their counter parts in Ming China, the only big difference will be the color scheme (I think
Besides Watchful I Studio's soon to be released stuff and Perry there are some other metal manufactures that have stuff for Asia:
Curteys miniatures has a wide array Chinese figures from many different time periods (no Ming though), but they are labeled as being 25mm which means I have no idea how they match up to WGF figures size wise. Cuteys also sells Burmese and Thai labeled as 28mm, 13th century mongol and samurai labeled as 25mm, Chinese pirates, and are the only people I know of to be selling Tibetans.
Renegade miniatures has warring state figures in 28mm.
Black hat has a bunch of non Japanese fantasy Asian miniatures for 28mm.
I know Wargames Foundry has stuff for the boxer rebellion, I think they may have some other things as well.
Pulp minis has figures for the boxer rebellion.
I think there are others but those I are the ones I know of for sure.
