Russia not to stand aloof on Iran sanctions: source

MOSCOW (Reuters) - Russia signaled impatience with Iran and growing acceptance of the West’s threat of sanctions on Tuesday, pointing to Tehran’s plans for new nuclear enrichment projects as a reason for pessimism about a diplomatic solution.

Russia would not be isolated if other powers reached a consensus on Iran sanctions, said a senior Russian diplomatic source, in Moscow’s most critical comments yet in the ongoing dispute over Tehran’s nuclear programme.

“If there is a consensus on Iran sanctions, we will not stand aside,” said the diplomatic source who requested anonymity due to the sensitivity of the situation.

“We will be thinking about sanctions but this is not an issue of the next few hours or weeks,” the source said, adding that Moscow did not want to complicate the situation with threats against Tehran.

Tehran caused an international outcry on Sunday when it announced plans to build 10 more uranium enrichment sites in retaliation for a rebuke by the U.N. nuclear agency for covering up an enrichment project for at least two years.

Western powers, Russia and China backed a U.N.-drafted nuclear fuel deal in October that was designed to allay international concern about Iran’s atomic activities, but Tehran declined it.

“We will not contribute to the complicated situation with threats of sanctions but we will have in view such prospects ... we are not going to remain isolated,” the source said.

Iran’s announcement that it planned to build new enrichment centers did “not add optimism to talks with Iran,” the source said, adding that Russia wanted Iran to cooperate openly and consistently with the International Atomic Energy Agency (IAEA).

“We would rather have Iran cooperating more openly and consistently with the IAEA and showing clear steps to lift concerns -- which are gaining greater foundation -- than introducing sanctions against Iran,” the source said.

Analysts said the comments showed that Moscow is tiring of Iran’s failure to allay Western fears about its nuclear programme and also irritated by growing criticism at Russia’s failure to deliver S-300 air defense missiles.

“In terms of general dynamics of course Russia is moving closer to sanctions,” said Fyodor Lukyanov, the editor of Russia in Global Affairs, who said Moscow was irritated with Tehran for not accepting its offer to enrich uranium.

“Russia is for sure angry at Iran for a few reasons, not only the general attitude of Iran. The Iranians are also very irritated at Russia’s stance, for example threatening an international court case against Russia over the failure to deliver S-300s,” he said.

Russia’s economic interests in Iran include building the Bushehr atomic power station. Once a source of disagreement between Russia and the West, the United States now says the plant removes any need for Iran to have its own uranium enrichment programme.
