The Park administration has a timetable for the exchange of high-level visits with Iran, Yun said when asked about when the president will visit the Islamic Republic, Yonhap News Agency reported on Tuesday.
The report added that South Korea's commerce minister will make a trip to Tehran next month for a meeting on economic and trade issues.
The visits will come a few weeks after the Joint Comprehensive Plan of Action (JCPOA), a lasting nuclear deal between Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany), came into force.
Based on the nuclear deal, reached in July 2015, all nuclear-related anti-Iran sanctions have been removed.
