Need some insight on common Business interactions in Vietnam!

Hi r/Vietnam! I'm in my first year at Uni doing Business, and am part of a group presentation team, and we need to it based on business in Vietnam. I have a few questions, if anyone has any answers I would be thoroughly grateful!

1. If I were to give a business presentation in Vietnam, would considerations would I have to make, as compared to doing one in England/The West?

2. How would a business meeting be run in Vietnam?

3. How a negotiation be carried out?

Any answers would be awesome, and links to relevant sites if possible! Cheers :)
