Tang–Tibet Treaty Inscription
The Tang - Tibetan Empire Treaty Inscription is a stone pillar standing outside the Jokhang Temple in Lhasa, Tibet Autonomous Region, China. The inscription is written in both Tibetan and Classical Chinese, concerning the Changqing Treaty between the Tibetan Empire and Tang Empire in A.D. 821/823. Amy Heller's book Tibetan Art describes it as one of the most important treaties between the Tang and Tibetan Empire. Inscription states the relationship of Tang and Tibetan Empire as uncle and nephew of same family.
