The United States and Armenia have signed a major framework agreement to develop the “Trump Route for International Peace and Prosperity” (TRIPP), a flagship project in President Donald Trump’s economic diplomacy playbook, while Yerevan continues its strategic pivot away from Moscow.

U.S. Secretary of State Marco Rubio, visiting Yerevan, joined Armenian Foreign Minister Ararat Mirzoyan in signing the deal, which advances a 43-kilometer road and rail corridor through southern Armenia linking Azerbaijan proper with its Nakhchivan exclave. Rubio called it “the most important step to date” toward a route designed to deliver peace and prosperity through economic connectivity. Additional agreements on restoring broad strategic partnership and cooperation in critical minerals were also signed.

The TRIPP project stems from a landmark August 2025 White House agreement between Azerbaijani President Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan, witnessed by Trump. Armenian officials, including Mirzoyan, have welcomed the initiative as “truly beneficial” for the country, with construction expected to begin in 2026.

Armenia’s geopolitical realignment

The TRIPP corridor and deepened U.S. partnership underscore Armenia’s accelerating drift from Russia. Long dependent on Moscow for security via the Collective Security Treaty Organization (CSTO) and economic ties through the Eurasian Economic Union, Yerevan grew disillusioned after Russia’s limited support during the 2020 and 2023 Nagorno-Karabakh wars and its focus on Ukraine.

Pashinyan’s government has frozen CSTO participation, bought Western arms (especially from France), strengthened EU and NATO-adjacent ties, and now positioned the United States as a key player in the strategically vital transit route – sidelining earlier Russian proposals that would have given Moscow greater control.

Moscow’s warnings

Russia has reacted with sharp warnings. Senior officials, including Dmitry Medvedev, have accused Pashinyan of leading Armenia down a “sorrowful path” akin to Ukraine’s. Moscow has threatened economic retaliation – higher gas prices, restricted market access, and complications for the large Armenian diaspora in Russia – while labeling the moves a “huge mistake” that makes Armenia a “hostage to Western geopolitical games.”

Despite retaining a military base in Gyumri and significant energy leverage, Russia’s influence in Armenia is visibly declining. The TRIPP agreement effectively replaces previous Russian-centric corridor plans, further weakening Moscow’s foothold in the South Caucasus.

Strategic implications

For Armenia, TRIPP offers infrastructure investment, transit revenue, jobs, and a chance to reduce reliance on Russia while normalising relations with Azerbaijan. For Washington, it represents a success in transactional diplomacy that diversifies regional connectivity away from Russian and Iranian influence.

Challenges remain significant: Armenia must carefully manage sovereignty concerns, border security, and potential Russian backlash. Domestic opposition and regional tensions with Azerbaijan and Turkey add complexity.

If successful, the Trump Route could become a model of turning historical conflict into shared economic interest. However, the speed of Armenia’s westward shift and Moscow’s growing irritation suggest the project will test whether economic incentives can truly outweigh traditional security dependencies in the volatile South Caucasus.
