Not in my school anyway. The languages taught here in Austria vary by school AFAIK, in my school everyone had to learn English, then depending on which branch we selected we could learn French, Italian, Spanish and/or Latin (but there was no path to combine French with Italian).

I looked it up and while it is possible for schools to choose other languages than these, Chinese doesn’t seem to be among them, so that could not be made a mandatory subject, probably could be taught as a non-graded elective though.
