Armenia and Azerbaijan will hold a new round of talks in Washington tomorrow Sunday in an effort to normalize their relations, the spokeswoman for the Armenian Foreign Ministry said today.

Tensions between the two countries are rising again over the disputed Nagorno-Karabakh region, where Russian peacekeepers were deployed in 2020 to end the war — the second between the two countries over the enclave since the 1991 collapse of Soviet Union.

This mountainous region is internationally recognized as part of Azerbaijan, but is inhabited mainly by Armenians.

“From April 30, the Minister of Foreign Affairs of Armenia, Ararat Mirzoyan, will be in Washington for a working visit. A new round of talks on the agreement on the normalization of relations between Armenia and Azerbaijan is scheduled,” spokeswoman Ani Badalyan wrote on her official Facebook page.

There was no official confirmation of the meeting from Azerbaijan.

Despite years of attempts, Armenia and Azerbaijan have not concluded a peace agreement, which would settle issues such as border demarcation and the return of prisoners.

Azerbaijan installed a new checkpoint last Sunday on the road to Karabakh — the Lachin Corridor — a move Armenia called a flagrant violation of a 2020 ceasefire.
