I've cut strings in China, in Beijing--I used the huge studios at the television network, CCTV, but I'm not sure how available they are. Oasis is a nice room--Google it for a contact number.
I don't know about ISDN lines, or even the practicality of trying to produce something remotely. He'll need a contractor, copyist, Mandarin speaking conductor, translator, etc. I've done all this, and know how to produce something over there, but it rests on my own personal relationships that enable me to put together a team that will take care of everything. He should consider going there himself. If I can be of assistance they can IM me.
At CCTV they have 2 large rooms, one with a Neve 88 and the other with an Oxford (16 bit). They have PT HD and Sony 48 track digital, and engineers who know how to handle PT transfers, and know how to mix to stems, etc.
