Six power talks to show unity on Iran - Germany

By Mark Heinrich

VIENNA (Reuters) - German Foreign Minister Frank-Walter Steinmeier said on Thursday a meeting of six big powers next Tuesday aims to show international resolve not to allow Iran to develop nuclear weapons technology.

"There are open questions which Iran urgently needs to resolve to reestablish lost trust. It remains the case that the international community cannot and will not permit nuclear weapons technology to be developed in this region," he said.

"We will be meeting in Berlin in a few days time with the respective Security Council members to debate how we can express demonstrable unity on these questions in the future," Steinmeier told reporters before talks with International Atomic Energy Agency Director Mohamed ElBaradei.

The West fears Tehran is secretly seeking an atom bomb. Iran says its nuclear program is only for power generation and a recent U.S. intelligence estimate it had stopped an active nuclear arms drive in 2003, compounding disagreement among the six powers over the next steps in the stand-off.

Germany's foreign minister and his counterparts from the five permanent members of the U.N. Security Council are expected to join the Berlin talks.

Germany wants a new U.N. resolution tightening sanctions against Iran, but Steinmeier said he and ElBaradei were discussing possible solutions and stressed the findings of the U.S. intelligence agencies must be taken into account.

"Recently we have seen new estimates on the status of research and development work (in Iran)," he said. "In this connection it is of course important what the (U.S. National Intelligence Estimate) has expressed."

A European official involved in negotiations said the estimate had set back the sanctions effort and eased pressure on Iran, notably because of stronger resistance by Russia.
