"I don't know which woman he was afraid of, the woman in the red dress or the secretary of state," State Department spokesman Sean McCormack said Friday, regarding the actions of Iran's Manouchehr Mottaki.
Later Friday, Iraq's foreign minister said United States and Iranian officials had met at ambassadorial level. Neither Rice nor Mottaki were in the meeting.
The dinner episode Thursday night amid a major regional conference on Iraq perfectly revealed how hard it was to bring together the top diplomats of the two rival nations.
Meanwhile, Iraq's neighbors on Friday negotiated a declaration that would pledge support for Iraq's embattled Shiite-led government in return for more inclusion of Sunni Arabs in the political process.
A draft copy of the six-page declaration said the summit participants would agree to support Iraq's government as long as it ensured the "basic right of all Iraqi citizens to participate peacefully in the political process through the country's political system."
In other developments:
Also Friday at the conference, Mottaki delivered a tough speech, blaming the U.S. military presence for Iraq's turmoil and demanding the release of five Iranians detained by U.S. forces in Iraq.
"There should be no doubt that the continuation of and increase in terrorist acts in Iraq originates from the flawed approaches adopted by the foreign troops," Mottaki said. "The United States must accept the responsibilities arising from the occupation of Iraq."
On the conference's other main front, Iraqi Prime Minister Nouri al-Maliki on Friday pushed Arab governments to stop foreign fighters from crossing their territory to join Iraq's insurgency, while trying to convince the Arabs that his Shiite-led government was serious about reconciling with Iraq's Sunnis.
Going into the summit, the Iraqi government had hoped for a breakthrough meeting between Rice and Mottaki. Instead, their only direct contact was a wary exchange of pleasantries over lunch Thursday, punctuated by a wry, somewhat mysterious comment by Mottaki.
Mottaki walked out of the diplomats' dinner on the pretext that the female violinist entertaining the gathering was dressed too revealingly.
The Iranian entered the lunch, greeting the gathered diplomats with the Arabic phrase, "As-salama aleikum," or "Peace be upon you," according to an Iraqi official who was present.
