Acting Deputy Prime Minister Mher Grigoryan said Tuesday, June 1 that contacts on the unblocking of transport communications in the region have recently been suspended.

Grigoryan and the Russian and Azerbaijani Deputy PMs co-chair a working group on the development of economic ties and infrastructure projects in Nagorno-Karabakh and the South Caucasus region.

"These works will be efficient if the situation is at least stable," Grigoryan said on Tuesday, Aysor.am reports.

"In this situation and given the tensions on the border, I don't think the work on that platform is constructive, contacts have been interrupted recently."

Grigoryan also noted that no secret document exists and that the Armenian side has not and is not going to discuss any "corridor" through the territory of Armenia.
