Iran has no specific expectations from the Paris meeting of the five permanent UN Security Council members and Germany, Iranian top envoy to Paris, Seyyed Ali Moujani, said on Tuesday.

"We are not waiting for anything specific. We have already made our decision" on Iran's nuclear program, said the charge d'affaires of the Iranian embassy in Paris.

"The fact that other countries take decisions does not indicatethat our diplomacy has suffered a setback of any kind. We have our own logic," Moujani told the Arab Press Club in Paris.

"Our first nuclear power plant is to start operating within a year," he said, adding: "For us, this is vital".

It is the first meeting at political director-level grouping Britain, China, France, Russia, the United States and Germany since the International Atomic Energy Agency announced Friday that Iran had not cooperated nor suspended its nuclear program.

Teheran remained inflexible over its nuclear program despite a UN injunction giving it one month to suspend all uranium enrichment activities.

Iran said Monday that it had seen no reason to comply with and it has written to UN Secretary General Kofi Annan to complain about the reported threat of a U.S. attack with or without UN approval.

The West is seeking at the Paris meeting a UN Security Council resolution that is expected to legally constrain Iran to obey to its obligations, diplomats said.

The closed-door talks will open the door for a foreign ministers' meeting of the six countries on May 9 in New York.
