Tehran is expecting to see a real change in the policies of U.S. President Barack Obama towards Iran, an Iranian government spokesman announced on Tuesday.

Earlier Obama stated that Tehran would become "one of our most important issues," and that his administration would adopt a new policy toward Iran.

"We are so far analyzing whether there are going to be any changes [in U.S. policies] or not, we are following the situation and will make a statement when the time is right," Iranian spokesman Gholam-Hossein Elham said.

Elham said that Iran "is awaiting concrete changes from new U.S. statesmen." He also said the United States "should accept it is a government within its own limits, not an empire."

"My job is to communicate to the American people that the Muslim world is filled with extraordinary people," Obama said during an interview on Monday night with the Al-Arabiya news channel.

"My job to the Muslim world is to communicate that the Americans are not your enemy. We sometimes make mistakes. We have not been perfect," the U.S. leader added.

He also said that, "The United States has a stake in the well-being of the Muslim world...the language we use has to be a language of respect. I have Muslim members of my family. I have lived in Muslim countries."

Obama had earlier pledged to address the Muslim world from a Muslim capital in his first 100 days in office. However, he declined to reveal the exact location of the promised speech during Monday''s interview.

The United States accuses Iran of developing nuclear weapons, a claim denied by Tehran, which maintains its nuclear program is exclusively for the energy needs of the country.

Diplomatic relations between the United States and Iran were cut in 1979 when supporters of the Iranian leader Ayatollah Khomeini seized the U.S. Embassy in Tehran, holding 52 employees captive for 444 days.
