Vice President JD Vance visited Armenia on Monday, becoming the first sitting U.S. vice president or president to do so, as the Trump administration promotes economic opportunities and a U.S.-brokered peace deal with Azerbaijan.

In Yerevan, Vance and Prime Minister Nikol Pashinyan signed an agreement advancing negotiations on a civil nuclear energy deal, while the U.S. offered investments in infrastructure, computer chips, and surveillance drones.

The visit follows an August agreement between Armenia and Azerbaijan to finalize a peace treaty and create a transit corridor connecting Azerbaijan and its Nakhchivan exclave, a key point in resolving the decades-long Karabakh conflict.

Vance emphasized a forward-looking approach to peace and planned to travel to Azerbaijan on Tuesday to continue negotiations, the AP has reported.

Pashinyan hailed the visit as historic, underscoring the strategic partnership between Armenia and the United States.
