Vice President JD Vance landed in Armenia on Monday — a country that no sitting U.S. vice president or president has visited before — as the Trump administration offered economic opportunities while it works to advance a U.S.-brokered deal aimed at ending a decades-long conflict with Azerbaijan. Vance and Armenian Prime Minister Nikol Pashinyan signed an agreement to push forward negotiations on a civil nuclear energy deal, and Vance said the U.S. was ready to export advanced computer chips and surveillance drones to Armenia, and invest in the country's infrastructure.
