Iran and Belarus Deepen Defence Ties with a Minsk Cooperation Pact
Iranian and Belarusian defence ministers signed a military-cooperation document in Minsk on 12 March 2025, formalising a partnership between two of the most heavily sanctioned states on Europe's periphery.
Iran and Belarus have formalised their defence relationship. On 12 March 2025, Iranian Defence Minister Aziz Nasirzadeh and his Belarusian counterpart Viktar Khrenin signed a military-cooperation document in Minsk, capping a year of steadily thickening contacts between two governments bound together mainly by their isolation from the West.
The agreement's text was not published in detail, and the official readouts — carried by Iran's state Mehr news agency and Belarusian outlets — spoke in the vague language of “exchange of experience” and “technology cooperation”. Independent reporting by Xinhua and analysis from the Jamestown Foundation confirm the ministerial meeting and place it within a broader Minsk-Tehran alignment that has accelerated since 2023.
The interesting question is what “technology exchange” covers. Both states are significant players in the drone war around Ukraine — Iran as the source of the Shahed loitering-munition design, Belarus as a logistics and training rear for Russian operations. Neither side has confirmed transfers, but the plausible content of any cooperation runs through unmanned systems, air-defence know-how, and the industrial workarounds both have developed to survive sanctions.
For Europe, the pact matters less as a bilateral event than as another node in the sanctioned-states network — Russia, Iran, Belarus, North Korea — that increasingly shares components, tactics and production tricks. The open question is whether Minsk becomes a conduit for Iranian technology into the Russian war effort, or whether the relationship stays largely declaratory.
