Edward Sapir notably used evidence of contact and diffusion as a negative tool for genetic reconstruction, treating it as a subject in its own right only at the end of his career (e.g., for the influence of Tibetan on Tocharian).
During the Han–Xiongnu War, the Chinese established a military seat at Wulei, north east of present-day Bugur with an aim to protect the Indo-European Tocharian statelets of the region and kept them away from the Xiongnu's aggression in the northeastern steppe.
In 1998, Chinese linguist Ji Xianlin published a translation and analysis of fragments of a Tocharian Maitreyasamiti-Nataka discovered in 1974 in Yanqi.
The native name of the historical Tocharians of the 6th to 8th centuries was, according to J. P. Mallory, possibly kuśiññe "Kuchean" (Tocharian B), "of the kingdom of Kucha and Agni", and ārśi (Tocharian A); one of the Tocharian A texts has ārśi-käntwā, "In the tongue of Arsi" (ārśi is probably cognate to argenteus, i.e. "shining, brilliant").
