“The additional pressure of our international partners on Baku is very important. We have heard statements from our various colleagues, but we don’t think this is enough,” Vahan Kostanyan said, AP reported.
Kostanyan previously also accused Azerbaijan of ignoring a ruling by the International Court of Justice ordering Azerbaijan authorities to ensure unimpeded movement in the Lachin Corridor, the only road from Armenia into Nagorno-Karabakh.
According to Armenian media, trucks and foreign diplomats are currently in the village of Kornidzor on Armenia’s border with Nagorno-Karabakh, which is at one end of the Lachin Corridor.
Azerbaijan’s Foreign Ministry said that it viewed Armenia’s attempt to send a convoy to Nagorno-Karabakh “under the guise of ‘humanitarian aid’” as a violation of Azerbaijan’s “territorial integrity and sovereignty.” 
The latest flare-up comes weeks following talks in Brussels and Washington aimed at calming tensions between the two countries after Azerbaijan opened a checkpoint on the Lachin Corridor in April.
At that point, the road had already been blocked for four months by demonstrators who were protesting what they claimed to be illegal mining and other ecological abuses by Armenians in the area.
