Afghanistan diversified trade via Iran's major port at:

1. Bandar Abbas
2. Chabahar
3. Karachi
4. Gwadar

Afghanistan’s growing trade volume through Iran’s Chabahar Port represents a strategic economic shift. Located in Iran’s Sistan-Baluchistan province, Chabahar offers Kabul sea access bypassing Pakistani ports. India’s investment in Chabahar’s development further incentivizes this route. This diversification reduces Afghan dependence on Karachi and strengthens Tehran-Kabul ties despite Western sanctions pressure on Iran.
