Türkiye and Armenia opened the Akhalkalaki-Kars railway line to Armenian imports and exports on May 24, with Türkiye's special representative for normalisation Serdar Kılıç saying the move would "improve quadruple cooperation among Türkiye, Armenia, Azerbaijan and Georgia" and Armenian Prime Minister Nikol Pashinyan thanking partners in Türkiye and Georgia. Pashinyan said the route gives Armenia rail access to Russia via Georgia and Azerbaijan, to China via Russia and Kazakhstan, and strengthens its connection with the European Union through Türkiye and Georgia. He added that rail links with Türkiye, Azerbaijan and Iran were expected to follow, capping a normalisation track that earlier this month included Vice President Cevdet Yılmaz's visit to Yerevan and the signing of a joint deal to restore the ancient Ani Bridge.

Foreign Minister Hakan Fidan and Syrian counterpart Asaad al-Shaibani made the announcement in Ankara as part of a broader strategic partnership.

Turkish Airlines Chairperson Murat Şeker said the conflict triggered by U.S. and Israeli strikes on Iran on Feb. 28 has allowed the carrier to capture more traffic between Europe and Asia from disrupted Gulf rivals. The airline has reallocated planes to Asian and African routes, with many flights over 90% full in March, and may raise its growth projections if demand holds. Şeker noted the carrier faces fuel costs at double pre-conflict prices but is coping through capacity adjustments and ticket surcharges.
