I don't believe China's going to "save" film, but I think not for a lot of the reasons people think.
I've been living in Beijing for two years now and keeping up shooting film even in the capitol is a hit and miss affair. C41 & E6 processing service is commonly available via sendout at Kodak Express outlets which are everywhere, and there are some pro labs as well that offer traditional B&W. The Wukesong Camera Market will sell you some version of anything related to photography you can imagine from digital P&S's to field cameras to studio lighting to traditional darkroom gear. The film selection isn't as broad as what you get stateside, but they stock C41, E6 and B&W in rolls and sheets. Kodak, Fuji, Ilford and Lucky were all represented. Some segment of the population is clearly still shooting film.
That said though, film is vanishingly rare in standard retail channels. The Kodak Express outlet near my school had a few rolls that I suspect had been in the display case a very long time. I have never seen a single roll or disposable camera in say, grocery stores.
The sense I get about film in Beijing is that it's the purview of a limited number of pros and well-to-do hobbyists, some casual older hold-outs who haven't taken to digital and possibly a segment of the working class for whom even a cheap digital camera is expensive. So, my impression is that film manufacturing carries on in China not because the population has special interest in it, but rather because it still fulfills a niche that digital isn't yet able to realistically fill. It's not a place that's ripe for a second analog coming.
