During the meeting on Sunday, the two sides conferred on the latest situation of economic and trade ties between Iran and Qatar, and discussed ways to boost the relations.
Zarif and the Qatari minister also underlined the need for removing trade barriers and facilitating the trade exchanges between the two countries.
The Qatari official is heading an economic and trade delegation to Iran.
Back in August, Doha decided to return its ambassador to Tehran, more than 20 months after he was recalled, and strengthen its ties with Tehran amid a diplomatic rift between Qatar and several other Arab countries, including Saudi Arabia, the UAE, Egypt and Bahrain.
The Arab countries allied with Saudi Arabia blame Doha for interfering in the domestic affairs of other states and sponsoring terrorism, an accusation Qatar has rejected as “groundless”.
The diplomatic crisis, the worst since the 1990 invasion of Kuwait by Iraq and the subsequent Persian Gulf War, has seen the Arab nations cut ties to Qatar, which hosts a major US military base and will be the host of the 2022 FIFA World Cup.
Doha has been receiving fresh food supplies from Iran, which has also allowed Qatar’s national carrier to use its airspace.
