Hen dee nun der. That good idea, if with Burma or Combudia i agree with you 100%, but not with Thailand. I hate them so much. This is my opinion.
You hate them because you are uneducated and jealous. You know there are hundreds of thousands of Lao people who go to work in Thailand and send millions of dollars back to Laos each year. In addition, there are almost two millions Thai tourists visiting Laos each year who spend millions of dollars to Lao economy and development. What have the Cambodian and Burmese done to contribute to Lao economy and development? Not much. They both are as poor as Laos and hundreds of thousands of their countrymen and women have to go to work in Thailand.
Whether you like it or not, exchanges between Laos and Thailand keep increasing each year and more and more bridges over the Mekong are being built.
