Both sides noted the significant potential for deepening and diversifying trade between the two countries.
Iran and Turkmenistan border the Caspian Sea and share a joint frontiers of over 1,000 km.

The Iran-Turkmenistan-Kazakhstan railway project, which was designed to intensify trade and economic ties in the Eurasian space, also plays a significant role in relations between the two countries.
The railway route Uzen-Gyzylgaya-Bereket-Etrek-Gorgan was commissioned in December 2014. The railway is designed to facilitate the optimization of cargo traffic throughout Eurasia.
Trade between Turkmenistan and Iran exceeded $2.62 billion in 2015, according to official figures.
