Amid escalating tensions along regional borders, Azerbaijan's State Border Service reported on July 25 that Armenia had planned a provocation at the troubled Lachin border crossing. The alleged plan involved the assembly of a number of vehicles.

This development took place on July 26, when a large convoy with 360 tons of humanitarian aid left Yerevan for Nagorno-Karabakh. However, the Azerbaijani border guards and Russian peacekeepers stationed at the "Lachin" checkpoint denied the convoy entry into the region.

This demonstrates Azerbaijan's decision to enforce its demand that the Agdam-Stepanakert/Khankendi road become the primary route for cargo deliveries, rather than the controversial Lachin corridor. According to President Ilham Aliyev's aide Hikmet Hajiyev, this stipulation resulted from an agreement reached during the recent trilateral meeting between Ilham Aliyev, Nikol Pashinyan and Charles Michel in Brussels.

However, the press secretary of the Armenian Prime Minister Nikol Pashinyan denies the existence of such an agreement in Brussels on the proposed route change.

Throughout the evening of July 26, Armenia's attempt to negotiate with the Russian peacekeepers and Azerbaijani officials proved ineffective.

The conflict underscores one aspect of the tense situation on the Azerbaijani-Armenian border, where both countries closely monitor border crossings and activities. The Lachin Corridor, originally controlled by the non-recognized Nagorno-Karabakh Republic, became a geopolitical flashpoint after the Second Nagorno-Karabakh War. 

The denial of passage to the large aid convoy served to highlight the disputed status of the Lachin Corridor. These tensions underscore the difficult relationship between the two nations and Russia, which serves as a regional peacekeeping force.
Recall that on April 23, 2023, Baku established a checkpoint at the entrance to the Lachin corridor, justifying it by the need to "prevent the illegal transportation of manpower, weapons and mines."

Armenia regards Azerbaijan's policy of restricting movement along the Lachin corridor as an attempt at ethnic cleansing in Nagorno-Karabakh.  Baku, in turn, suggests that Nagorno-Karabakh Armenians use the Agdam road to obtain necessary products. At the same time, Azerbaijan insists on the need to "reintegrate" the Karabakh Armenians, but they firmly reject this demand of Baku.
