Addressing a joint press conference with his Iraqi counterpart Salim al-Jabouri in Tehran on Saturday, Larijani said they discussed a range of issues in their meeting this morning, particularly ways to counter the threat of terrorism in Iraq.
Apart from closer political coordination, Iran and Iraq are going to develop more serious security cooperation in order to cleanse the region of terrorists, Larijani added.
Iran is concerned about the fate of Muslims in the region, he went on to say.
The Iranian speaker also noted that he and Jabouri talked about the expansion of trade ties, saying both neighbors seek a jump in bilateral trade by removing the existing obstacles.
Jabouri arrived in Tehran on Saturday morning for talks with senior Iranian officials on the latest situation in his country.
Iran and Iraq have enjoyed growing ties ever since the overthrow of the former Iraqi dictator, Saddam Hussein in 2003.
Iran, a close ally of Iraq, has been also supporting the Arab nation in the fight against Daesh (ISIL) since the terrorist group invaded Iraq in summer 2014.
