The American Secretary of States Hillary Clinton is in Moscow to try to persuade Russia to support American policy on Iran. The US wants Russia to agree to the option of imposing additional sanctions on Iran if it does not suspend its uranium enrichment program by the end of the year. Richard Galpin reports from Moscow. As a permanent member of United Nations Security Council, Russia has the power to veto resolutions. And Moscow has always said it does not believe sanctions are an effective way of promoting change. But recently, President Medvedev has indicated his government made ultimately accept that sanctions are inevitable. There are other big issues to be discussed while Mrs. Clinton is in Russia, including the plan for Moscow and Washington to sign a new treaty in early December for a further cut in their large arsenals of nuclear weapons.
