US Vice President Vance's South Caucasus Tour Signals Deepening Engagement, Nuclear Deal with Armenia

Historic Diplomatic Tour in the South Caucasus

US Vice President J.D. Vance undertook a landmark diplomatic visit to the South Caucasus this week, with stops in Armenia on February 9, 2026, and Azerbaijan on February 10, 2026. This marks the highest-level visit by a US official to the region in decades, underscoring a strategic pivot by the United States into an area traditionally considered within Russia's sphere of influence.

During his tour, Vice President Vance engaged in high-level discussions with Armenian Prime Minister Nikol Pashinyan in Yerevan and Azerbaijani President Ilham Aliyev in Baku. The visit aimed to strengthen bilateral ties, foster regional stability, and advance economic cooperation, building on a US-brokered peace framework between Armenia and Azerbaijan established in August 2025.

Landmark Nuclear Cooperation with Armenia

A central outcome of Vance's visit to Armenia was the signing of a significant nuclear cooperation agreement. The 'Agreement on Cooperation between the Government of the Republic of Armenia and the Government of the United States of America in the Field of Peaceful Use of Nuclear Energy,' also known as a 123 Agreement, was finalized with Prime Minister Pashinyan.

This accord is projected to facilitate substantial US investment in Armenia's energy sector, potentially involving up to $5 billion in initial US nuclear-related exports and an additional $4 billion in longer-term fuel and maintenance contracts, totaling $9 billion. The initiative aims to support Armenia in replacing its aging Soviet-era Metsamor nuclear power plant with advanced US small modular reactor technology, thereby enhancing Armenia's energy security and reducing its historical reliance on Russian energy supplies.

Strategic Partnership with Azerbaijan and Regional Connectivity

In Azerbaijan, Vice President Vance and President Aliyev signed a Strategic Partnership Charter. This agreement encompasses various areas, including regional connectivity, economic investment, and security and defense issues. The US also committed to providing 'new boats' to Azerbaijan to bolster the protection of its territorial waters.

Discussions in both capitals also focused on the 'Trump Route for International Peace and Prosperity' (TRIPP) project. This proposed transit corridor through Armenia is designed to connect Azerbaijan to its Nakhchivan exclave, aiming to create a new east-west trade artery that bypasses traditional routes through Russia and Iran.

Shifting Geopolitical Landscape

Analysts view Vice President Vance's extensive engagement in the South Caucasus as a clear indication of the United States' intent to increase its influence in a region where Russia has historically been the dominant external power. The timing of the visit, amid Russia's ongoing conflict in Ukraine, is seen by some as creating opportunities for the US to expand its diplomatic and economic footprint. The US approach emphasizes transactional diplomacy and economic partnerships to foster stability and reduce regional dependencies on other major powers.
