For some time after the collapse of the USSR, the Caspian Sea continued to belong to two states, namely Russia, as the successor to the USSR, and Iran. However, this caused serious contradictions between the coastal newly formed post-Soviet countries overthe use of the Caspian Sea water area, seabed and subsoil. To solve such problems, it was necessary to establis h a new legal status of the Caspian Sea, taking into account the interests of all Caspian littoral states.At the initiative of the Russian Federation, work began in 1996 on a draft convention on the lega l status of the Caspian Sea, which was to be oriented towards the interests of all littoral states. Including more than 50 meetings and 5 summits, the draft Convention reached its culmination in 2018 in Aktau. The purpose of this research paper is to examine Iran's perspective on the legal status of the Caspian Sea and assess the impact of the Aktau summit on Iran. The paper analyzes Iran's role in the negotiations and its position on various issues related to the legal status of the Caspian Sea. Through this analysis, the paper aims to provide insight into the complexities of the Caspian Sea legal framework and its implications for Iran's interests and its relations with other littoral states.
