U.S. Vice President JD Vance arrived in Azerbaijan on Tuesday, a day after visiting Armenia, as part of a regional tour aimed at strengthening a U.S.-brokered peace process between the two neighbors.

The visit follows U.S. President Donald Trump's mediation last year of a peace agreement between the historical rivals Baku and Yerevan, which have fought two wars over the Karabakh region.

On Monday, Vance held talks with Armenian Prime Minister Nikol Pashinyan in Yerevan and he is to meet Azerbaijan's President Ilham Aliyev in Baku.

The visit is expected to advance a flagship transport communications project integrating the two countries into a new east-west trade route.

Azerbaijan seized Karabakh in a 2023 lightning offensive, ending three decades of Armenian occupation.
