Vietnam doesn't have the population to be the next China. I wish them the best, but their time will not last nearly as long as China. (or more likely it lasts as long but it is shared with a bunch of other countries in Asia, Africa, and/or South America)
Nowadays, with so much automation going around, Vietnam can afford to become the next China even without a comparable population. Not that I think it will, but see the story of the Four Asian Tigers to realize how smaller countries can suddenly have a much bigger importance to the world economy.
