For this to be possible, this HSR will have to travel across Vietnam to Thailand. 

It is obvious that it will continue to Malaysia and finally to Singapore.

Countries like Laos and Cambodia can extend their rail lines to join the main HSR. It is not only logical but necessary if they want to trade and earn $$$$$$$$$$$$$$$$$$$$$$$ and PROFIT, PROFIT, PROFIT AND MORE PROFIT for the well being of their respective people.
