Airbus wont be opening the operation on their own; they will have a Chinese partner. The Chinese partner will do the inviting for a foreign pilot and depending on their experience with foreign pilots may be able to guide you through the licensing procedure.
There is, as far as I know a small operation in Chongqing but I cannot think of one that is big enough to cater for heavy maintenance.
The difficulty is going to be with the CPL(H) level. CAAC ALTP(H) is fairly straightforward once you learn how to get through the hoops. The company I worked for took on a CPL once but trying to get him through the Mandarin only exams proved too difficult.
I have a feeling that Citic Helicopters may be the one that would tie up with Airbus as they already do the heavy maintenance on the PLA's Harbin Z9s (Dauphin).
