VIENNA, Austria -- Russia and China on Tuesday scuttled a Western attempt to introduce a resolution on Iran's nuclear defiance at a meeting of the International Atomic Energy Agency, diplomats said.
The decision appeared to be the result of lingering unhappiness by the two world powers about not being informed earlier of plans for such a resolution.
It came a day after the UN Security Council imposed another round of sanctions on Iran for refusing to suspend uranium enrichment. Iran defiantly vowed to continue its nuclear program, which it insists is aimed only at generating power.
Moscow on Monday had threatened not to back the new UN sanctions against Iran unless the West gave up its IAEA resolution plans.
Then on Tuesday it signaled that it was ready to back such a document if it was given substantial input in drafting it before deciding later in the day that it was against it after all, said the diplomats, who spoke on condition of anonymity because the information was confidential.
Asked why Russia and China were opposed, one of diplomats said Moscow decided to withdraw its support "on principle" and Beijing, which often takes a cue from Russia on the Iran nuclear dispute, followed suit.
A senior Western diplomat said the decision to scrap plans for a resolution was jointly taken by the six powers taking the lead on engaging Iran on its nuclear program -- the United States, Russia, China, Britain, France and Germany.
He said the six felt that new UN Security Council sanctions passed Monday to punish Iran had sent enough of a message.
Gregory L. Schulte, Washington's chief IAEA delegate, said the new sanctions resolution underscores "that Iran's file remains open" and backs the IAEA's right to continue its probe of Tehran's past nuclear program, particularly attempts to make weapons.
But two of the other diplomats, speaking separately, insisted the resolution was scrapped because of Russian and Chinese opposition and said any suggestions of unity on the issue were an attempt to cover up an East-West split among the world powers.
A draft of the resolution, marked "restricted" and made available to The Associated Press, reflected Western attempts to ramp up pressure on Iran using the IAEA as a venue.
It said the board "firmly supports" attempts by IAEA Director General Mohamed ElBaradei to shed light on past experiments "that could have a military dimension" -- shorthand for alleged attempts by Iran to develop nuclear arms.
It cites ElBaradei in calling such alleged programs "a matter of serious concern." And it "deeply regrets" Tehran's refusal to suspend uranium enrichment -- a possible pathway to nuclear arms -- despite four Security Council resolutions demanding it do so.
