I seriously doubt Thailand will ban foreign ownership of vehicles. That would be ridiculous.
I think Laos allows foreigners to own vehicles, but they have different colored license plates. You can tell what is local and foreign owned by looking at the color.
Black lettering on yellow = privately owned, Lao national
Light blue lettering on yellow = privately owned, foreign national
Black lettering on white = company owned, Lao ownership
Light blue lettering on white = company owned, foreign ownership
