Goetz considered the Tokharian origin of Lalitaditya's minister Chankuna (IAST: Caṇkuṇa) as an evidence of the Kashmiri hegemony over the Turkic kingdoms. According to Kalhana, Lalitaditya brought Chankuna to Kashmir from the Tuhkhara land (Tokharistan). "Chankuna" is believed to be a Sanskrit transcription of the Chinese title "jiangjun" ("military general"). Goetz speculated that Chankuna was a Tokharian general in Chinese army, and introduced the Chinese warfare techniques in Kashmir, which enhanced Lalitaditya's military campaigns. Sen criticizes this theory, pointing out that Kalhana's writings acclaim Chankuna for magical powers, not military expertise. Moreover, the Tokharian origin of Chankuna cannot be considered as concrete evidence of Kashmiri control over southern Hindukush region.
