During Maliki's three-day visit to the Islamic state, Iranian officials have said Tehran supports peace and security in the neighbouring country.
"Iran will always be on the side of the popular government of Iraq," the state news agency IRNA quoted First Vice-President Parviz Davoudi as saying in talks with Maliki on Sunday.
"Helping the establishment of security in Iraq has always been one of Iran's main policies."
The student news agency ISNA quoted Maliki as saying in Tehran: "Iraq's territory cannot be used by any country for harming Iran's security."
An Iraqi spokesman said last week Maliki wanted to discuss evidence of Iranian intervention in Iraq and the two countries' overall relationship.
Help for Iraq on electricity
It was not clear whether the issue was discussed during Maliki's meetings with Iranian officials.
"Because of the mounting cooperation among Iraqi groups, security problems are gradually being removed," IRNA quoted Maliki as saying in talks with Davoudi. "Iraq's security will have a positive impact on security in the Middle East."
IRNA also quoted Iranian president Mahmoud Ahmadinejad as saying in talks with Maliki: "Iraq's neighbours have more responsibility to help the country to establish peace and security."
In Baghdad, a statement issued by Maliki's office after his talks with Davoudi said the two men had discussed measures to improve political, economic and trade relations as well as steps to support the electricity and services sectors in Iraq.
Iraq suffers from severe power shortages.
The two leaders also discussed efforts to overcome obstacles preventing progress in relations between their countries on investment and services, the Iraqi statement said.
"Iraq is looking forward to Iranian companies taking part in developing its infrastructure," the statement quoted Maliki as saying.
