Blue Spot
"They are our brothers," said Tsogtsaikhan Gombo, a former adviser to the Mongolian Prime Minister and head of a local think tank. Koreans and Mongolians are very close ethnically, he said, noting that children of both nations are born with an unusual blue spot at the base of their spine, which later fades. As the nearest Soviet satellite, Mongolia also adopted orphans from the North during the Korean War in the early 1950s. (Link)
Interesting ! The last I was in Ulaan Bator two years back I was surprised to see so much Korean influences on Mongolian youth culture - music, fashion, tv, etc. And it seems that many Mongolian youth also head to South Korea for further education. One of our Mongolian friends has been there for two years already in fact.
