Azerbaijan toward Iran

Iran toward Azerbaijan
-25Iran has cooperated with Azerbaijan on cross-border infrastructure, including transport and water projects. At the same time, Iranian officials have criticized Azerbaijan’s relationship with Israel, and tensions escalated after the 2023 attack on Azerbaijan’s embassy in Tehran. Iran’s response and the subsequent restoration of embassy operations have not erased these underlying security concerns.
Overall relationship
-20The relationship combines concrete infrastructure cooperation with recurring strategic and security friction. Cross-border transport and water projects provide a practical basis for engagement, while Iranian concern over Azerbaijan’s ties with Israel and the 2023 embassy attack have strained relations. Neither cooperation nor confrontation alone defines the bilateral structure.
