What do you think are the most common culture challenges for Vietnamese and foreigners working together?

After receiving so many feedback on difficult professional relationships between foreigners and Vietamese, Some of these feedback come from top management foreigners with mid management Vietnamese reporting to them. Some from my time at an international bank from foreigners reporting to a Vietnamese manager. Some are from professional Vietnamese who have a lot of frustration trying to communicate and develop a positive professional relationship with foreign colleagues.

I'm hopeful in designing a workshop to bridge this cultural gap for both foreigners and locals that will be very practical, bridge the gap and bring cultural understanding and acceptance. If you have any personal experiences to share, let us know the situation and what you would advise others to do. Thanks!
