Visas - married couple with different nationalities

I am British and my wife is Indonesian. We currently live in Indonesia. We are considering a job prospect for me in China, but don't know how our different nationalities would affect our situation when applying for entry permits. I understand I would have to stay in the UK for 3 months while my Z1 type is processed, but could my wife go with me or would she have to do the same in Indonesia for her S type?
