DAVOS, Switzerland - Iranian President Hassan Rouhani said on Wednesday it was possible to turn more than three decades of enmity with the United States into friendship if both sides made an effort.

He was speaking in a Swiss television interview after arriving at the World Economic Forum in Davos where he will court the global business community and meet a series of oil company executives on Thursday.

Asked whether there could one day be a US embassy again in Tehran instead of the Swiss embassy representing US interests in Iran, the president told public RTS television: "No animosity lasts eternally, no friendship either lasts eternally. So we have to transform animosities into friendship."
