If there were this would have come out by now, not just from the survivors but also the relatives and other associates of such foreign nationals. They would be on file somewhere, someone would remember seeing them etc and from the lack of evidence it is likely the answer will be no.
Hilfskreuzer Kormoran and Michel did employ Chinese taken from the crews of merchant ships they sank. However, as from 9th December 1941 Germany was officially at war with China. The employment of enemy civilians is unlikely by the KM, although of course forced labour was widespread in Nazi Germany, particulary by the SS. And what happened to the Chinese on Michel is not clear, presumably they had to be handed over to the Japanese at Singapore.
It may also be worth noting that Korean labourers were ''employed'' in cleaning out the oil bunkers of the Uckermark when she was in Yokohama. This was at the time of the fatal explosion on Uckermark that also burned out the hilfskreuzer Thor. There were suggestions that the explosion was a Soviet inspired sabotage....
