Iranian Foreign Minister Manouchehr Mottaki will visit Baghdad on Friday, Iraqi officials said.
Officials in the Foreign Ministry, speaking on condition of anonymity because they are not authorized to talk to media, said Mottaki would arrive early Friday and would meet with Prime Minister Nouri al-Maliki and other Iraqi officials.
Mottaki was also expected to hold a news conference before leaving the country the same day.
The Iranian minister was supposed to have come to Iraq on May 15 but the visit was delayed.
Mottaki's predecessor, Kamal Kharrazi, visited Iraq last year and the two sides issued a joint statement blaming Saddam Hussein for the bloody 1980-1988 Iran-Iraq war.
