PM Nikol Pashinyan, who deepened ties with US, faces challenge from pro-Russia parties in upcoming parliamentary polls.

Armenia has signed a strategic partnership agreement bolstering ties with the United States, as Prime Minister Nikol Pashinyan faces a challenge from pro-Russia parties in the country’s upcoming election in June.

US Secretary of State Marco Rubio and Armenian Foreign Minister Ararat Mirzoyan also signed a framework on critical minerals and cooperation on a transit corridor in the Armenian capital of Yerevan on Tuesday.

“This agreement marks the biggest step to date on making this historic route a reality, on advancing peace, and on increasing prosperity in Armenia and frankly in the region,” Rubio said at a signing ceremony at the Yerevan airport.

The 43-km (27-mile) corridor, dubbed the Trump Route for International Peace and Prosperity (TRIPP), would traverse southern Armenia and provide Azerbaijan with a direct route to the exclave of Nakhchivan and into Turkiye, a close ally of Baku.

Pashinyan has sought closer ties with the US and Europe, drawing the ire of longtime ally Russia. Moscow has said that it could raise the price of gas Armenia receives from Russia if it continues to pursue greater integration with Western countries.

Armenia had historically been a close security and economic partner of Russia, but Yerevan started to turn towards the West for alliances after the 2023 conflict in the Nagorno-Karabakh region of Azerbaijan.

Russia, which is fighting its own war in Ukraine, did not intervene militarily when Azerbaijan launched a major military offensive Nagorno-Karabakh, which had a large Armenian population and had been de facto independent since the 1990s.

Last year, the US and Armenia held joint military drills for the first time.

“I wish to reaffirm that the comprehensive strategic relations between our two nations are stronger than ever,” Mirzoyan said of relations with the US on Tuesday.

The administration of US President Donald Trump, for its part, has cast its relationship with Yerevan in largely economic terms and sought concessions in areas such as critical minerals.

“We are laying the groundwork for the sort of economic engagement that allows Armenians to make money and find prosperity and Americans to do the same and to do it together, which is one of the strongest ways to bind nations with one another,” Rubio said on Tuesday.

A US State Department framework for the transportation corridor, part of a peace agreement signed by Armenia and Azerbaijan last August, also grants the US a 74 percent share in the “TRIPP Development Company”, with an explicit pledge to benefit US companies.
