Isn't there an ancient Swedish/Asian connection, or am I dreaming that?
I have no idea. If true, it would be very interesting.
I think you are probably referring to a Finnish/Asian connection. It is theorized that the Finns are related, racially and linguistically, to the Hungarians, who in turn are related to the Koreans. Interestingly, the Korean word for their own nation and language is Han-gul or Han-guk. Think also of the "Huns."
Knowing Swedish, I can tell you that the Finnish language is nothing like the Scandinavian languages of Swedish/Norwegian/Danish. And based on the Korean I used to know, and having seen Finnish, I could believe they are related.
