I have been to Vietnam and actually had the opportunity to briefly check out a girl's breast implants up close. She didn't speak very good English, so I couldn't much information out of her. They looked nice, especially in clothes, but this girl in particular got her incisions through the areola. Not under the areola, like literally across the areola. Imagine circle with a line that goes almost exactly half way though the areola. When I first saw them all I could think was "man, the surgeon sure did a sloppy job, something like this would never happen in a more developed country". This is just my personal anecdote based on one experience, but I would recommend against getting a boob job in Vietnam. Going to Thailand would certainly be a better option if you need to get it done in an Asian country.
Edit:
Also, here is a slightly longer version of the video OP uploaded.
