Now is 21 century, I think Lao people need to learn the good lessons from other countries in terms of race.
No matter of people races, as long as they can do good jobs for Laos or Lao people, I think, it would be fine.
Take USA, Australia or even Singapore as example, foreigners can be their PR or citizens easily, if the foreigners are met their requirements. That's why their economies are prosperous. They got talented people that can help them.
