That is what I thought last summer when I noticed the Hangul lettering cha-dong–mun or main entrance written on the door of the bus that On and I took from Savannakhet to Mukdahan, Thailand.
The only thing that I could think of at the time is that some bus company sold these buses to a bus company in Laos.
It’s the only thing that makes sense with the Korean lettering still visible on the bus door.
Well, I noticed the same Korean lettering for “main entrance” on the bus On and I took from Vientiane to Paksong this time. Obviously some company in Korea sold a lot of used buses to a bus company in Laos.
And then, I noticed more Korean lettering on the bus we took from Luang Prabang back to Vientiane as well as other buses at the Nanluang Bus Terminal (in fact, one bus still had the name of the bus company in Hangul written on the outside of the bus).
I am surprised that a lot of the Korean lettering and signs have not been removed inside of the buses or for the lettering on the sides of the buses painted over.
