Some people may not think it is notable, but to give a local example drives home that Wikipedia is very diverse. If you are presenting in China, please don't forget to mention that we have places for people to build Wikipedias in Yi, Zhuang, Tibetan, Uyghur, and many other languages.
I don't disagree with this, but it's probably worth noting that languages are intimately connected to culture, nationalism, and politics, so when to mention what can sometimes be a sensitive issue. In China, in particular, promoting of regional languages is often connected to promoting regional political independence (i.e. secession from China, or at least increased autonomy), so needs to be done somewhat carefully so we don't become seen as a meddling US-based political organization that's trying to break apart China or something like that.
