Russian and Azerbaijani foreign ministers discussed preparation for an Armenian-Azerbaijani peace treaty in a telephone call Saturday.

Sergey Lavrov and Jeyhun Bayramov confirmed the need to step up efforts to normalize relations between Azerbaijan and Armenia, the Russian Foreign Ministry said in a statement.

They also spoke about unblocking transport communications and delimitation of the Armenian-Azerbaijani border.

The Azerbaijani army initiated an anti-terrorism operation last month in Karabakh to establish constitutional order in the region, after which illegal separatist forces in the region surrendered.

Azerbaijan, having now established full sovereignty in the region, has reiterated its request to the Armenian population in Karabakh to become part of Azerbaijani society.
