Chinese and Arabic are both there, within the admittedly long and difficult to navigate language selector! They are both in "beta" and hence further down the list. The reason Chinese is in beta is because it doesn't have word boundary detection, pinyin transliteration, or word frequency lists. Arabic is in "beta" because there were some issues with "right to left" text. I think this is working pretty well now though, haven't had complaints in a while, so I can think about bringing that out of beta soon.
