vietnam - blue sky prospect

Im not sure if this has been mentioned, I came across it today by chance. But it is a few months old.

This company called Keppel Investments brought a 20% share in Kris energy (Nens Vietnam partner). The significance is Keppel is the largest builder of offshore rigs in the world and made this statement:

 
"As an investor, we believe that KrisEnergy's portfolio has long-term growth potential and could offer sustainable returns over the long run," said Keppel's CEO Choo Chiau Beng in a statement.  

Now while Kris enegy have other prospects, I can't help but think Vietnam is the key growth potential prospect they saw. Maybe someone who knows of their other prospects may clarify this.

Any thoughts ?
