Armenian President Serzh Sargsyan will on Tuesday start a two-day working visit to Moscow, the presidential press service reported.
On Wednesday, Sargsyan will meet with President Dmitry Medvedev and take part in the fourth congress of the Union of Russian Armenians dedicated to its 10th anniversary.
The union was set up in 2000 as a Russian public organization and is led by entrepreneur Ara Abramyan, a Unesco goodwill ambassador.
Russia is a mediator in Armenia's conflict with Azerbaijan over the mountainous region of Nagorny Karabakh, a predominantly ethnic Armenian region.
The conflict first erupted in 1988, when the area claimed independence from Azerbaijan and sought support from Armenia. Karabakh has been de facto independent since a 1991-94 war that claimed more than 30,000 lives on both sides.
