. Would be interesting for those who choose to fly back to Thailand instead of a land border. Are they going to get the same response? I can't see how Laos can stop you from leaving without a legal reason (eg a wanted fugitive )but Any country can stop you from entering for any reason they see fit.
My opinion is it's a Thai influenced decision in that respect that also benefits Laos 2nd hand.
Wether this affects actual visa holders is another interesting question.
