Iran's chief nuclear negotiator told European Union foreign policy chief Javier Solana that Tehran would welcome constructive dialogue with six world powers, state television said on Monday. Iran's Saeed Jalili talked with Solana over the telephone, state television said. Last week, the United States and five other major powers said they would invite Tehran to a meeting to discuss its disputed nuclear programme. In their conversation, Solana called for the continuation of talks between the two sides aimed at a new era of cooperation, the Iranian television report said, without saying when it took place. Jalili "welcomed dialogue between Iran and the six countries on constructive cooperation ... he emphasised the necessity of correct understanding of international realities and developments," it said.
