YEREVAN.- The statement issued by Russian, U.S. and French leaders proves there are active processes around resolution of the Nagorno-Karabakh conflict, said spokesperson for the opposition Armenian National Congress (ANC) Arman Musinyan.

“We should be cautious as the Karabakh problem is among the most important political issues,” Musinyan said adding that the ANC will issue a statement in the near future.

Speaking of ANC’s future moves, spokesperson said the scenarios are not final as political processes are developing dynamically. He said the ANC will speak about its future steps during the May 31 rally.
