I never connected Korea and Thailand in that way, but those NEMA/round pin combos were even lurking around here at some time, so I assumed they migh be used in Korea as well. However, the Kropla list shows Schuko plugs as well, so it's probably just an idea of them using 4.8 mm pins. Doesn't make much of a difference, although they can't get their plugs into female Euro cord caps. There are weird things around, I even have an old ungrounded plug with 4.8mm pins, no idea where it comes from. Seems my guess was wrong. Anyway, it was just a guess.
I think PAL/SECAM sets were sold in the GDR. Even some Panasonic video recorders for PAL/SECAM east found their way there. I have one of those (although sold in Vienna) with a sticker on top proudly presenting: SECAM (DDR) reception!
