STOCKHOLM (Reuters/AFP) - The European Union said on Friday Iran had to choose between EU assistance for peaceful development of nuclear power or tougher sanctions if it failed to abandon its suspected atomic weapons programme. If they are ready to engage with us, we are ready to cooperate with them. If they decide to go for confrontation, then confrontation will happen, Swedish Foreign Minister Carl Bildt, whose country holds the EU presidency, told reporters. We have a very generous offer on the table. We want cooperation with Iran on quite a number of things including the development of civilian nuclear technology, he told reporters at a meeting of EU Foreign Ministers in Stockholm. Swedish Prime Minister Fredrik Reinfeldt, speaking at a separate Press conference, said Europe needed to remain united in its opposition to Irans nuclear programme. I think its very important for us to be gathered firmly in the EUs reaction towards Iran , not accepting nuclear ambitions, he said. EU foreign policy chief Javier Solana, who has led Western negotiating efforts with Iran , said he had yet to see the proposals. Lets see when we see it. Finnish Foreign Minister Alexander Stubb said he hoped Iran would respond to overtures from US President Barack Obama. Obama has set a deadline for discussions with Iran ... if we get no progress in the negotiations on nuclear proliferation then there will be more sanctions - its quite clear. Germanys European Affairs Minister Guenter Gloser said as he arrived for the informal talks: We dont want to impose more sanctions.But there must not be a N-arms race in the ME, he added. Gloser also voiced concern at the continued arrest in Iran of those using their right to the freedom of expression. French Foreign Minister Bernard Kouchner questioned the usefulness of pursuing negotiations on the nuclear dossier with Tehran indefinitely. What is productive is that the Iranian people have shown a determination to move towards a different form of democracy, the French minister added. Meanwhile, Reinfeldt said Iranian President Mahmoud Ahmadinejads appointment of terror suspect Ahmad Vahidi as Defence Minister was a provocation. We feel a situation where we often come back to provocations. Of course, I saw that this assignment was done as one of these examples, Reinfeldt told reporters.
