MOSCOW, April 29 (UPI) -- The Russian Foreign Ministry said before the six-nation meeting in Shanghai on the Iranian nuclear issue between Russia, China, the United States, Britain, Germany and France that the talks should focus on developing new "positive" proposals for Iran this time.

Moscow must have remembered that the latest U.N. Security Council resolution on Iran was accompanied by a statement of the six mediators about the possible alterations to their standpoint, "positive" for Iran. And it looks like the United States, as well as the three major European nations -- France, Germany and Britain -- have not supported an interim resolution that would rule out a serious toughening of the sanctions.

The latest U.N. Security Council Resolution, No. 1803, includes a travel ban imposed on a number of Iranian nationals who are known to participate in the development of that country's nuclear program, a freeze of several Iranian companies' and banks' accounts, and a compulsory inspection of all cargoes.

The Islamic republic was given 90 days to think, beginning on Feb. 22. What are the chances of Iran amending its position?

Anton Khlopkov, executive director of the Center for Political Studies, a Russian think tank, said at the Moscow meeting that Iranian politicians were almost unanimous about whether the country should carry on its nuclear energy program. They might only differ on how Iran should build its relations with other nations with regard to its nuclear dossier, and whether it is advisable to resort to such harsh rhetoric and demarches as Iranian President Mahmoud Ahmadinejad and his team do.
