“We want to see the ceasefire respected. The recent wave of violence, which began on July 31, was of great concern to us,” Warlick stated.

He noted that this kind of violence is a setback at the ability to reach a peaceful settlement.

“We need to work and re-double our efforts at the negotiating table to find solution. A starting point for that is respecting the ceasefire,” he said.

He noted that there is also an opportunity for the Armenian and the Azerbaijani presidents to come together either at the NATO summit that will be next week in Wales, and also on the margins of the UN General Assembly.

“[US] Secretary [of State John] Kerry as well, is prepared to be personally involved if his involvement is helpful and bringing about the settlement.

“The fact is that it is not enough for the presidents or the foreign ministers to meet on an occasional basis. We need a sustained process that lead to the conclusion of a peace agreement. And the way that we need to do that is through negotiation. So my message is ‘let’s get started,’” the American diplomat said.
