In page Tungusic languages:

"

Tungusic is today considered a primary language family. Especially in the past, some linguists have linked Tungusic with Turkic and Mongolic languages in the Altaic language family. However, a genetic, as opposed to an areal, link remains unproven. Others have suggested that the Tungusic languages may be related (perhaps as a paraphyletic outgroup) to the Koreanic, Japonic, or Ainu languages as well (see Macro-Tungusic).
