"We remain committed to a diplomatic solution. The intention is not to push Iran into further isolation but to find a way to bring Iran back to the negotiating track," Austrian Foreign Minister Ursula Plassnik told a news conference after a meeting of EU foreign ministers in Brussels this afternoon.

The EU, she said, is prepared to offer a cooperation package and to support Iran's development of a sustainable and proliferation-proof civilian nuclear program, if international concerns were fully addressed and confidence in Iran's intention established.

The cooperation package will contain three elements, a modern proliferation-proof nuclear technology element, there will be an economic element and a political element, said Plassnik whose country holds the current EU Presidency.

EU foreign policy chief Javier Solana said prior to the meeting that the EU is preparing to make a "bold" offer to Iran, including possible security guarantees, to persuade Tehran to curb its atomic plans.

"It will be a generous package, a bold package, that will contain issues relating to nuclear, economic matters, and maybe, if necessary, security matters," Solana said.

On May 19, five permanent members of the U.N. Security Council and Germany will hold a talks on the Iran nuclear issue in London, and the EU is expected to table the new package to the meeting.
