Sergei Lavrov said on Saturday that the council resolution must be written to include a time limit and specific measures for ending the sanctions. He denied that Russia was blocking the resolution.
The five permanent members of the Security Council (the United States, Britain, France, China and Russia) are considering a resolution in connection with Iran's nuclear program. The draft text calls for a series of nuclear and ballistic missile-related trade sanctions, a freeze of assets related to Tehran's nuclear program and travel bans on scientists involved in the Islamic republic's nuclear program.
Russia and China, however, have been reluctant to support tough sanctions. On Friday, Russia said the draft text put forward by France, Germany and Britain required major changes.
The US ambassador to the UN John Bolton, called the Russian changes extensive, and said Washington would circulate its own version of the sanctions plan.
Iran says as a signatory of the Nuclear Non-Proliferation Treaty, it has the right to develop a civilian nuclear program.
Washington has accused Tehran of using its nuclear program as a cover to secretly acquire a nuclear weapon, a charge Iran denies.
