At the end of the visit, the two countries signed agreements to co-operate in transport, power, telecommunications, agricultural equipment manufacturing.
Under the agreements, the two countries were to jointly construct the Chitungwiza-Harare railway line, the extension of Kariba Power Station and establishing a tractor manufacturing plant.
The Zimbabwe National Chamber of Commerce and the Iran-Africa Co-operation Council also signed an agreement for co-operation between the private sectors of the two countries.
The visit also comes at a time when both countries are under siege from the West --- Iran for its uranium enrichment programme and Zimbabwe for its land reform programme.
The United States and its western allies believe Iran's uranium enrichment programme is ultimately aimed at producing fissile material for nuclear weapons.
But Iran insists it will use the enriched uranium only to fuel nuclear power stations, something it is permitted to do as a signatory to the Nuclear Non-Proliferation Treaty.
Harare undertook agrarian reforms to empower the majority of its people and this courted the ire of Britain, the US and their western allies.
But Cde Mugabe and President Ahmadinejad have stood their grounds in defence of their governments' programmes and resisting foreign interference in the internal affairs of their countries.
Axis of evil indeed...
