Azerbaijan on Monday criticized Armenia for its attempts to avoid commitments to open the Zangezur corridor and for proposing alternatives deemed "unrealistic" by Baku.

"Armenia should put an end to false excuses to evade its commitments to link the Zangezur corridor and roads/railways, according to the tripartite declaration signed in November 2020," the Azerbaijani Foreign Ministry said in a statement.

It also noted that ignoring previous negotiations between the two countries and proposing three "unrealistic" checkpoint options to connect Azerbaijan to its western exclave Nakhchivan is "not a good policy."

Zangezur was part of Azerbaijan, but in the 1920s, the Soviets gave the region to Armenia. After this move, Azerbaijan lost its link with Nakhchivan and some parts of the railway between the two countries were destroyed.

Azerbaijan has focused on projects in the Zangezur corridor, which will include highways and rail lines stretching across territories in Armenia's Syunik region.

Once those parts are repaired, Azerbaijan will be able to reach Iran, Armenia and Nakhchivan uninterruptedly by train.

The statement came in response to a post shared by Armenian Prime Minister Nikol Pashinian on Twitter on the opening of three checkpoints on the Azerbaijan-Armenia border.

"A draft decision of the Government of Armenia on opening of 3 checkpoints on the Armenian-Azerbaijani border to provide connection between eastern Azerbaijan and Nakhchivan is being formally circulated for several months. Government of Armenia is waiting for positive reaction from Azerbaijan," Pashinian wrote.

Relations between the former Soviet republics of Armenia and Azerbaijan have been tense since 1991 when the Armenian military illegally occupied Karabakh, a territory internationally recognized as part of Azerbaijan, and seven adjacent regions.

Clashes erupted on Sept. 27, 2020, with the Armenian Army attacking civilians and Azerbaijani forces, violating several humanitarian cease-fire agreements.

During the 44-day conflict, Azerbaijan liberated several cities and around 300 settlements and villages that had been occupied by Armenia for almost 30 years.

The fighting ended with a Russian-brokered agreement on Nov. 10, 2020, which was seen as a victory for Azerbaijan and a defeat for Armenia.

However, the cease-fire has been broken several times since then.

After the conflict ended, Azerbaijan launched a massive reconstruction initiative in the liberated Karabakh region.
