MiG-29s are designed in Russia, and used by many nations worldwide
Russia has signed a contract to deliver 20 MiG-29 fighter planes to Burma, Russian media reports say.
The contract is worth 400m euros (£356m; $570m), sources close to the Russian arms firm Rosoboronexport say.
Many countries in the West have imposed sanctions against Burma, in response to its poor human rights record.
But the country’s military rulers still receive many goods, including arms, from its neighbours China and India, as well as Russia.
The Kommersant newspaper said Russia had already given 12 MiGs to Burma in 2001.
In the 1990s, Burma bought Chinese military aircraft to the value of about $2bn, a source at Rosoboronexport told the Vedomosti business daily.
