Iranian Foreign Minister Mohammad Javad Zarif is planning to visit North Korea, Iran's state television reports, without giving the date of the visit.
"The date of this trip will be set and announced soon," the television on Sunday quoted Zarif as saying. It gave no further details.
North Korea's top diplomat, Ri Yong Ho, whose country faces international and US sanctions, visited Iran in August as the United States reintroduced sanctions against the Islamic Republic.
