It seems they only package, finish and distribute film under the Sunny brand. It seems to be Ferrania.
Not sure if they actually produce film. On this page: http://www.chinacsky.com/co/35150/ t lists Colour film and digital paper as some of their products with the place of origin for film being in China.
