In a traditional briefing on September 11, Matthew Miller, the Press Secretary of the US State Department, said that the US is deeply concerned about the rapid deterioration of the humanitarian situation in Nagorno-Karabakh.

"We reiterate our call for the immediate and simultaneous opening of the Lachin and Aghdam routes to enable the passage of much-needed humanitarian supplies to the men, women, and children of Nagorno-Karabakh, as the Secretary of State said in his statement over the weekend. We urge leaders not to take any action that escalates tensions or detracts from this goal, as the Secretary of State has done in his calls. I should also say that, in addition, we have consistently emphasized the need to open routes in Nagorno-Karabakh and conduct dialogue between the parties. Although it is important for Nagorno-Karabakh to have reliable representatives for this process, as we said earlier, we do not recognize Nagorno-Karabakh as an independent and sovereign state, and therefore, we do not recognize the results of the so-called presidential elections announced in the last few days," he said.

Miller said that the United States will continue to strongly support efforts to resolve the outstanding issues of Armenia and Azerbaijan through direct dialogue. "Secretary of State Blinken and Senior Adviser on Caucasus Negotiations Bono have consistently dealt with this, and we will continue to deal with the issue continuously," the press secretary noted.

In response to the question that the first US-Armenia military exercise in Armenia was intended to prevent a potential attack by Azerbaijan, Miller said: "No, not at all. We regularly train, operate, and improve interoperability between our armed forces to maintain our readiness. Armenia is a long-standing partner of the United States and has had an ongoing relationship with the Kansas National Guard since 2003 as part of the Department of Defense's State Partnership Program. No, this is just a regular training that is not related to other events in any way."

Miller answered the question about Russia's attitude towards the Armenian-US exercise. "I think that considering that Russia has occupied two of its neighbors in recent years, it should refrain from lecturing the countries of the region about security measures," the press secretary noted.
