I built a couple of older Chinese tanks and used the same green I'd used on Soviet tanks for the green and a sand/tan colour I matched from photos online. I don't have FS numbers for either of them. They look right enough. Sorry no photos, they're over on PhotoBucket right now so I can't link to them.
AK Interactive does make this set. I picked them up for some modern Chinese tanks I've done some work on if you need them to be accurate.
