In a real world, no economy is perfect.
The problem of Vietnam is that it is a small country with ambitions, or we can say it is too greed. Right now, I think Vietnam is the key card the western used to fuck up the Asia financial market, just as the Bosnia for European in 1990s. When this combined with Iran crisis, the nuclear effect will be generated, and there will be a new world order.
Time is key, and determination of the rest of world is also a key.
