TEHRAN, Iran (AP) – While Syria said Wednesday it would send an aide to a Baghdad-organized conference of Iraq’s neighbors that America plans to attend, Iran said it was considering whether to take part.

Ali Larijani, the head of Iran’s Supreme National Security Council, said Iraqi Foreign Minister Hoshyar Zebari contacted Iranian Foreign Minister Manouchehr Mottaki to discuss the conference.

“We are reviewing the proposal,” Mr. Larijani was quoted by the state TV Web site as saying Wednesday.

“We support solving problems of Iraq by all means and we will attend the conference if it is expedient,” Mr. Larijani said. “We believe Iraq’s security is related to all its neighboring countries, and they have to help settle the situation.”

Syria will be represented at the conference by Ahmed Arnous, an aide to the foreign minister, a Syrian Foreign Ministry official said, speaking on condition of anonymity because the plans had not yet been formally announced.

Washington’s willingness to attend the conference, to which Baghdad invited Iran and Syria, marked a diplomatic turnabout after months of refusing dialogue with Tehran over calming the situation in Iraq.

Secretary of State Rice announced a day earlier that the United States would join the meeting, planned for mid-March, and said Washington supported the Iraqi government’s invitation to Iran and Syria.

Asked by reporters if Iran was running a risk by attending the conference alongside the Americans, Mr. Larijani replied, “One should not commit suicide because one is afraid of death” – meaning Iran should not hurt itself just to avoid possible negative results.

Many Iranians feel resentful over the last major diplomatic dialogue with America, when officials from both sides met before the 2001 American invasion of Afghanistan to topple the Taliban, whom Tehran also opposed.

Iran backed the invasion – only to see Mr. Bush name the country part of the “axis of evil” later.

Mr. Larijani did not say what level delegate Iran would send if it chose to attend the conference. Ms. Rice said Tuesday that the March gathering would be at a sub-ministerial level, which would be followed by a full ministerial meeting, possibly in early April.

Along with Iran and Syria, Iraq has invited Bahrain, Egypt, Jordan, Kuwait, Saudi Arabia and Turkey to the discussions. Other Arab countries have not confirmed their attendance or the level of delegates they would send.

British Prime Minister Tony Blair’s spokesman said he hoped the proposed meeting would produce results.

“Meeting is good, but results have to flow from meetings. We welcome contact, but equally what we want to see is hard, concrete results – that’s on the ground in Iraq, that’s on the ground in Lebanon, that’s on the ground in terms of influence used in Palestine as well,” said Mr. Blair’s spokesman, on customary condition of anonymity.

Iran has said in past months that it is willing to meet with America to discuss how to calm the violence in Iraq. But tensions have increased dramatically between the two countries recently.

President Bush has stepped up accusations that Iran is backing anti-American Shiite militants in Iraq, a number of Iranians in Iraq have been seized by America forces and the American military presence in the Gulf has been beefed up.

At the same time, Washington has led a push for stronger sanctions against Iran over the country’s nuclear program. America accuses Iran of seeking to build nuclear weapons, a claim Tehran denies. The United Nations has demanded Iran suspend uranium enrichment before any negotiations over its nuclear program can be held, a condition Tehran has rejected.
