U.S. Secretary of State Antony Blinken on June 29 said hard work remains to be done to reach an agreement between Armenia and Azerbaijan after the conclusion of three days of talks in Washington between the two Caucasus countries' foreign ministers. Armenian Foreign Minister Ararat Mirzoyan and counterpart Ceyhun Bayramov were meeting in an attempt to settle decades-long disputes and to seek a permanent solution to the crisis over the breakaway region of Nagorno-Karabakh, which is populated by ethnic Armenians but lies within Azerbaijani territory. Blinken cited agreement on some matters but didn't provide details. The ministers didn't comment.
