YEREVAN (Combined Sources)-Armenian President Serzh Sargsyan is set to travel to Russia on January 18 for talks with Russian President Dmitri Medvedev, the Armenian president's spokesman Samvel Farmanyan said Thursday at a press briefing.

According to Farmanyan, the two leaders will discuss strategic relations and cooperation between the two countries as well as the possibility of a tri-lateral meeting between Sargsyan, Medvedev and Azeri President Ilham Aliyev.

"It's natural that the Presidents of Armenia and Azerbaijan can meet both separately and in other formats unless the Karabakh conflict is solved. There is nothing extraordinary here. On the contrary, it would be strange if such meetings did not take place," Farmanyan said.

"As a Minsk Group Co-Chair country, Russia makes serious efforts to solve the Karabakh issue and Armenia highly appreciates these endeavors," Farmanyan said. "Thanks to the efforts of the President of the Russian Federation, there have been two meetings in the trilateral Armenia-Russia-Azerbaijan format."

The news of Sargsyan's scheduled visit came as Turkish Prime Minister Recep Tayyip Erdogan wrapped up a high-level visit to Moscow Wednesday where he met with counterpart Vladimir Putin for talks on energy cooperation and the Nagorno-Karabakh conflict.

Sargsyan's Defense Minister was also in Moscow Wednesday on a working visit aimed at reviewing Armenia's close military ties with Russia and their future.

Ohanian's talks in Moscow coincided with the start of a two-day visit to Armenia by Russian Foreign Minister Sergey Lavrov. The latter met with President Sargsyan and Foreign Minister Eduard Nalbandian.

According to the Armenian presidential press office, both the Karabakh negotiating process and the Turkish-Armenian rapprochement were on the meeting's agenda along with bilateral issues.
