This corridor connects China to CIS countries (Kazakhstan, Uzbekistan, Turkmenistan) via Iran, supporting Iran export logistics. The route starts in Xi’an, China, and reaches Iran’s Aprin dry port of Chabahar port transit, reducing transit times from 30–40 days by sea to 15 days by rail. It facilitates central Asia trade routes for electronics, machinery, and textiles, with Sarakhs rail link serving as a key node for Uzbekistan and Turkmenistan. This route aligns with the Belt and Road Initiative Iran, enhancing CIS market access.

3. Chabahar-Milak-Sarakhs Route

The Chabahar port transit route connects Iran’s only oceanic port on the Gulf of Oman to Central Asia via the Sarakhs border with Turkmenistan. The 1,350-km Chabahar-Sarakhs railway, nearing completion, has a capacity of 8.5 million tons annually, offering landlocked CIS countries access to the Indian Ocean. This route supports central Asia trade routes and strengthens Iran-CIS trade by bypassing congested Caspian ports.

4. Caspian Sea Route

Iran’s Caspian Sea ports (Amirabad, Anzali) facilitate transit services through Iran to CIS countries like Russia, Azerbaijan, and Kazakhstan. This route supports rail freight CIS by transferring cargo from ships to trains at ports like Bandar Abbas for onward transport to Central Asia. Iran’s oil swap deals with Kazakhstan and gas pipelines with Turkmenistan leverage this route for energy transit (Middle East Institute).

5. Iran-Turkey-CIS Route

This road-based route connects Turkey to CIS countries via Iran, supporting cross-border customs Iran. Since its launch in October 2021, approximately 1,000 trucks have transited from Turkey to the UAE, carrying consumer goods and machinery. Since October 2021, it has facilitated approximately 1,000 truck transits from Turkey to the UAE, reducing transit time from 21 days by sea to 6 days for routes to the Mediterranean, benefiting regional trade Atlantic Council (Atlantic Council). It aligns with sustainable transit Iran goals by reducing sea freight dependency.
