“Armenian and Azerbaijani officials said Thursday that they had agreed on the text of a peace agreement to end nearly four decades of conflict between the South Caucasus countries, a sudden breakthrough in a fitful and often bitter peace process…

However, the timeline for signing the deal is uncertain as Azerbaijan has said a prerequisite for its signature is a change to Armenia’s constitution, which it says makes implicit claims to its territory.

Armenia denies such claims, but Prime Minister Nikol Pashinyan has repeatedly said in recent months that the country’s founding document needs to be replaced and has called for a referendum to do so. No date has been set.”
