Peace_treaty_between_China_and_Tibet_(822)
The Changqing Treaty (Chinese: 長慶會盟) is a peace treaty signed between Ralpacan of the Tibetan Empire and Emperor Emperor Muzong of the Tang dynasty in 822.
It follows an earlier peace agreement signed by the Emperor Dezong of Tang with the Tibetan Empire in 783, which will then be overridden by the Tibetan Empire.
The treaty would serve as a basis for Tang–Tibet relations.
