I've mentioned this to the team before. Real lack of good quality business Chinese learning materials out there, and I for one would pay a fair bit of change for some quantity and quality content on these topics.

One of the "decent" ones out there is http://www.learnoutloud.com/Catalog/Languages/Chinese/Business-Companion-Chinese/15886 thought it suffers from what most other similar learning materials out there suffer from, which is slow / unnatural pace of discussion and lack of modern expressions and concepts.

One good thing it does have is the topics it covers such as typical business meetings, negotiations, presentations, etc.

I think Helen's suggestion for legal content is good, but could probably only touch on the major stuff, since this is a highly technical field, even in English. Still, there is merit there.
