Taiwan's Wan Hai will be calling again at Shaheed Rajayee and Bushehr within days, the FNA news agency reported, while three more were expected back soon.
The deputy head of the Iranian Ports and Maritime Organisation, Ali Jahandideh, said: "We have had enormous measures on entrance of local and foreign shipping lines to Shaheed Rajayee Port as a container port."
The opening up of Iran follows the easing of US sanctions.
