Western diplomats² are circulating a discussion paper proposing further UN sanctions against Iran over its nuclear programme.

西方外交官正在讨论一份促使联合国对伊朗核问题进行进一步制裁的文件。

Iran says it only wants nuclear power for peaceful purposes

The measures include expanding travel bans and asset资产，有用的东西 freezes on people connected with the nuclear industry.

The move comes despite Iran's apparent acceptance of a deal to send most of its low-enriched uranium abroad in return for research reactor研究反应堆 fuel rods燃料棒.

Washington has called on Iran to match its words with actions.

Last month, diplomats said Iran had informed the International Atomic Energy Agency国际原子能组织 (IAEA) that it did not accept the terms of the deal and had instead demanded a simultaneous同时的 exchange on its territory.

The US and its allies fear Iran is attempting to develop nuclear weapons. Iran insists its nuclear programme is entirely⁴ peaceful.

Preliminary discussions

On Wednesday, a Western diplomat¹ confirmed reports that the discussion paper being circulated by the US talked about expanding travel bans and asset freezes on those connected to Iran's nuclear industry, as well as financial measures such as placing restrictions限制 on its banks.

In particular, it suggested targeting senior members of the Islamic Revolution Guard Corps⁶ (IRGC), which oversees⁷监督，审查 Iran's nuclear programme and its strategic weapons, they said.

The BBC's Barbara Plett, at UN headquarters in New York, says this is very much a preliminary stage, as the US and its European allies on the Security Council would have to eventually win agreement from Russia, which has been reluctant to不情愿的 pursue sanctions, and China, which openly opposes them.

An apparent policy shift in Iran also complicates⁸ things, she adds.

On Tuesday, President Mahmoud Ahmadinejad said Iran would have "no problem" sending most of its low-enriched uranium abroad so it could be processed into fuel, as envisaged面对，正视 by a deal struck in October between Iran, the IAEA and the so-called P5+1 - the US, Russia, China, UK, France plus Germany.

"We have no problem sending our enriched uranium abroad," he said.

"We say: We will give you our 3.5% enriched uranium and will get the fuel. It may take four to five months until we get the fuel."

"If we send our enriched uranium abroad and then they do not give us the 20% enriched fuel for our reactor³, we are capable of producing it inside Iran," he added.
