The sides will discuss deteriorating security situation in Iraq, where Washington accuses Tehran of backing sectarian militias.
Hoshiar al-Zibari said: "Iraqi representatives will of course attend the meeting. Iraq is not only hosting the talks, but is a fully-fledged participant in the talks."
U.S. Ambassador to Iraq Ryan Crocker met with Iran's ambassador to Iraq, Babak Dehghanpisheh, on May 28, the first meeting between senior officials of Washington and Tehran since 1979, when the two countries severed diplomatic ties. They agreed to establish a three-way commission on defense and security issues.
According to the Iraqi foreign minister, the second round of U.S.-Iran consultations will start amid progress in the political situation in Iraq, as radical Shia (Moqtada al-Sadr) as well as Sunni (Iraqi Accord Front) representatives are returning to the government shattered by a recent boycott by four Sunni ministers, who had protested over the way Iraqi Prime Minister Nouri al-Maliki, who heads of the Shiite-dominated government, handled legal proceedings against one of their Sunni colleagues.
