Russia says President Vladimir Putin is due to host talks in St. Petersburg on June 20 between the leaders of Azerbaijan and Armenia about the conflict over the breakaway region of Nagorno-Karabakh.
Kremlin aide Yury Ushakov said on June 14 that by organizing the meeting between Azerbaijani President Ilham Aliyev and his Armenian counterpart, Serzh Sarkisian, Russia was "continuing its mission as a mediator" in the conflict.
Sarkisian and Aliyev last met in Vienna in May, after a truce in early April halted four days of fierce fighting in and around Nagorno-Karabakh between Armenia-backed separatists and Azerbaijan's military.
Baku and Yerevan have been locked in a conflict over Azerbaijan's breakaway region of Nagorno-Karabakh for years.
Armenian-backed separatists seized the mainly Armenian-populated region from Azerbaijan during a war in the early 1990s that killed some 30,000 people.
Diplomatic efforts to settle the conflict have brought little progress.
