Visa for a non resident belgue

Hello
Good morning
I have a Belge guy who must get his Chinese visa in Brussels. He lives in Brazil, but was requested to go to Norway soon for a trainning course - which didin´t allow us to have time to get it here in Rio de Janeiro.
What are the documentation he need to start the application?
How long does it take to be stamped on his passport? Can we apply as a urgent?

Thanks for your attention.
