Müller's identification became a minority position among scholars when it turned out that the people of Tokharistan (Bactria) spoke Bactrian, an Eastern Iranian language, which is quite distinct from the Tocharian languages.

A few scholars argue that the Yuezhi were originally speakers of Tocharian who later adopted the Bactrian language.
