This fair is the outcome of signing of the trade treaty between the erstwhile Bushahr state and Tibet in the end of the 17th century (1679-1684).

The Lavi fair started after trading treaty between the Hindu Raja of Bushahr, Kehri Singh (1639-1696), and the government of (Tibet) Lhasa (dGa' ldan pho brang) headed by Bio bzang rgya mtsho, the Fifth Dalai Lama (1617-1682).

The result of their mutual cooperation during the war was a sworn agreement stipulating that no taxes be levied on Bushahri and Tibetan merchants when trading on each others' territories, an official delegation from Bushahr should be sent tri-annually to the towns of Tsaparang, Purang, Dawa, Ruthog and Gartok in western Tibet.

For the small Himalayan state of Bushahr, the Tibet-Bashahr treaty of 1679-1684 was undoubtedly of great economic importance.
