Tehran, Iran ? Supreme leader Ayatollah Ali Khamenei said Tuesday that he approves of talks between U.S. and Iranian officials on Iraq, but warned that the United States must not try to “bully” Iran.

It was the first confirmation that Khamenei, who holds final say on all state matters in Iran, is in favor of the talks.

His comments came hours after President Bush spoke in favor of such a meeting, saying American officials would show Iran “what’s right or wrong in their activities inside of Iraq.”

Khamenei said that “if the Iranian officials can make the U.S. understand some issues about Iraq, there is no problem with the negotiations.”

“But if the talks mean opening a venue for bullying and imposition by the deceitful party (the Americans), then it will be forbidden,” he said in a speech in the northeastern city of Mashhad, aired on state television.

Both the United States and Iran have said the talks will focus solely on stabilizing Iraq and not deal with the heated issue of Iran’s nuclear program. No time or place has yet been set for talks.
