VIENNA (Wall Street Journal) —The U.S. has backed away from pursuing a number of tough measures against Iran in order to win support from Russia and China for a new United Nations Security Council resolution on sanctions, according to people familiar with the matter.

Among provisions removed from the original draft resolution the U.S. sent to key allies last month were sanctions aimed at choking off Tehran’s access to international banking services and capital markets, and closing international airspace and waters to Iran’s national air cargo and shipping lines, according to the individuals.
The UK and Germany, concerned that Russia and China would reject the resolution outright and preferring to turn up pressure on Iran gradually, persuaded U.S. officials to drop or soften several elements, including some of the document’s harshest provisions, the individuals said.
U.S. officials said they wouldn’t comment on the day-by-day negotiations taking place among the Security Council members. But they acknowledge that there has been a tension between seeking the strongest possible sanctions at the UN and still maintaining consensus among the five permanent members of the Security Council and Germany, which are drafting the sanctions.
The disclosure of weakened proposals came as U.S. officials sought to persuade Russia and China to back measures against Iran in a conference call on Wednesday among the five permanent members of the Security Council and Germany, the first such meeting including China since mid-January.
Russia and China didn’t endorse a draft resolution, but signaled that they were open to further discussions, people familiar with the matter said. Russian Deputy Foreign Minister Sergei Ryabkov told Interfax news service, “We are continuing the process of comparing the approaches of the parties and considering further options.”
Russia and China also have been working in tandem to press Iran to accept a United Nations-brokered proposal to send uranium abroad for enrichment, Russian officials said Wednesday. The effort is unusual, coming from the two powers usually least inclined to lean hard on Tehran. “The clouds are gathering, and the position of Iran leaves less and less space for diplomatic maneuver,” a senior Russian diplomat told reporters Wednesday.
