Can I teach in UAE or Vietnam with a criminal record?

Good day all. My name is Bradley and  I am from South Africa. I am new to the site. This is my first post and I must say an embarrassing one.

I have a DUI on my criminal record. it is my only offence and it happened five years ago. Is it still possible to teach in the UAE or Vietnam with this blemish on my record?

I am really hoping for good news!
