The presidents of Armenia and Azerbaijan are traveling to Russia's Black Sea resort of Sochi on August 8 to meet individually with Russian President Vladimir Putin and possibly gather for a trilateral meeting.
The visits of Armenian President Serzh Sarkisian and Azerbaijani President Ilham Aliyev to Sochi come amid heightened tensions between the two Caucasus nations over the Nagorno-Karabakh region, where there has been sporadic fighting for days.
At least 20 people have been killed.
Azerbaijan claims Nagorno-Karabakh as part of its territory, but the region has been occupied and administered by pro-Armenian forces for some 20 years.
On his official Twitter feed, Aliyev on August 7 said "we will restore our territorial integrity either by peaceful or military means," adding that, "The war is not over. Only the first stage of it is. But the second stage may start too."
The Armenian side has expressed its readiness to hold a three-way meeting during Sarkisian and Aliyev's two-day visit to Sochi, but such a meeting has still not been confirmed.
