"The United States seeks to restore its status in Iran as they enjoyed before the Islamic Revolution (in 1979), and they will not accept less than this," Khamenei said in a meeting with the Iranian Foreign Ministry staff in the capital Tehran.

"The United States has basic and fundamental problem with the (Islamic) establishment," Khamenei was quoted as saying.
