回复：open a business company

your friend should consult with a business attorney. setting up a business is complicated. even small businesses here will take it very serious to consult with real professionals working in the realted fields. If your friend has a "very big company" and according to what your said, a multinatioanl, he should have known what is the right way to do it. he shouldnt have asked you to ask people here.

first thing your friend has to answer is the business he wants to set up here is of what legal structure?

here's a good website in plain English for you and your friend to get some very basic ideas about how to setting up a business here.
