When Turkish soldiers got to Korea to fight in the Korean war as part of the UN contingent, they and the Koreans could speak, if haltingly.
Turks, Koreans, Finns, and some Baltics have linguistic similarities and if you look at Finns and Baltics, like my wife’s uncle’s wife and in laws, the physical similarities are evident.
Well, the Turks did originate around Mongolia and the steppes, just west of Korea, many centuries ago.
