Armenia's Prime Minister Nikol Pashinyan said on Monday that the Russian proposals on Nagorno-Karabakh had not been discussed with the US side.
"Within a month period, I had only five talks with representatives of the United States, three of which were with US National Security Advisor Robert O'Brien and the other two were with Secretary of State Mike Pompeo," Pashinyan added during a press conference on the Internet.
"They did not discuss the Russian proposals, but rather the American proposals for a ceasefire." he continued.
Pashinyan emphasized that he spoke with Russian President Vladimir Putin regularly, sometimes five or six times per day.
On November 9, Armenia and Azerbaijan signed a ceasefire agreement concerning Nagorno-Karabakh.
The Kremlin announced that Russian President and his Azerbaijani counterpart Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan signed a joint declaration on a ceasefire in Nagorno-Karabakh, which went into force on the tenth of November.
The ceasefire declaration stipulates that the Armenian and Azeri forces will remain at their current locations, and Russian peacekeepers will be deployed along the line of contact in Nagorno-Karabakh.
The agreement also includes lifting restrictions on movement, transit, and the exchange of prisoners between the two parties of the conflict, and the return of the displaced to Karabakh, under the auspices of the United Nations High Commissioner for Refugees.
The Nagorno-Karabakh conflict goes back to February 1988, when the Autonomous Karabakh District declared its secession from the Azerbaijan Soviet Socialist Republic.
Armed confrontations took place between 1992-1994, in which Azerbaijan lost its control of Nagorno-Karabakh and other neighboring areas.
