Russia has announced its 2017 Eurovision entry, appearing to end speculation it might boycott the competition, being held in Ukraine, for political reasons.
Julia Samoilova will represent Russia in Kiev in May with the song Flame is Burning, state TV said on Sunday.
The two nations have been locked in political conflict since Russia annexed Crimea three years ago.

Ultra-conservative lawmaker Vitaly Milonov said that Russians would be "unwelcome guests in a country seized by fanatics".
Ukraine is hosting the competition after its singer Jamala caused an upset by winning in Sweden last year.
Her song, 1944, was about Joseph Stalin's mass deportation of the Crimean Tatars during World War Two.

In addition to the Crimea flashpoint, Ukraine accuses Moscow of arming separatist rebels in its eastern Donbas region, in a conflict that has claimed 10,000 lives since 2014.

However, there is already controversy surrounding the validity of Samoilova's participation, following reports she performed in Crimea in June 2015.
The Ukrainian security service (SBU) have previously blacklisted artists and performers deemed to have supported the Russian annexation.
Kremlin Spokesman Dmitry Peskov, speaking to Russian news agency TASS, denied that Samoilova's selection was Russian provocation.
He said: "Undoubtedly, we would like to avoid politicising the Eurovision contest.
"We believe it absolutely unacceptable as far as the development of this international contest is concerned."
