Amursana fled west to Siberia and sought asylum from the Russians at their fortress in Semipalatinsk (modern Semey, Kazakhstan).
He was then taken to Tobolsk where he died of smallpox on 21 September 1757, aged 35.

The Chinese demanded the return of the fugitive and his followers under the terms of Article X to the Treaty of Kiakhta, but the Russians hid the facts behind his flight and death hoping to gain leverage through the possession of his body.
After Qing envoys were told that Amursana had died crossing the Irtysh River, they spent the next month dredging it but found nothing.
After a long period of wrangling, the Russians finally agreed to ship Amursana's frozen body from Tobolsk to Kiakhta for viewing but refused a request that it be handed over for "posthumous punishment"; they instead buried it.
Repeated Qing requests to St. Petersburg for the return of Amursana's corpse were rebutted by the Russians on the grounds that their amicable relations should not be upset by "a few rotten bones".
Qianlong piled on the pressure: he placed Russian Orthodox monks in Beijing under house arrest and threatened to cut off trade altogether.
In the end, Amursana's body was not returned.
 Qianlong's insistence that "The state only needs to capture Amursana.
When he has died, and his body is retrieved, the entire [D]zungar affair can be called a success", failed to convince the Russians to return the body.

Qianlong's obsession with the matter appears to have been influenced by his grandfather Kangxi's treatment of the body of his arch-enemy Galdan Boshugtu Khan, whose head was placed on public display and his ashes crushed on the military parade ground in the Chinese capital.

On 18 October 1768, both parties signed an amendment to Article X of the Treaty of Kiakhta in the Russian, Manchu and Mongol languages prescribing punishments that would apply to future criminals, including defectors.
However, as the border with Dzungaria had not been defined at the time of the original 1727 treaty, Amursana and his compatriots did not qualify.
