Russian Foreign Minister Sergei Lavrov said yesterday that international efforts to resolve the Iranian nuclear standoff should be aimed at bringing Tehran back to negotiations.

"We will follow the earlier reached agreement that all measures to be considered should aim solely to bring Iran back to the negotiating table," Lavrov was quoted as saying by the Interfax news agency.

He made the remarks prior to a London meeting of foreign ministers from France, Britain, China, the United States, Russia and Germany that have offered Iran an incentives package, in exchange for a freeze on its uranium enrichment activities.

"There are possibilities for a settlement, and we will actively use them at today's meeting in London," Lavrov said.

"The main criteria is to rest on facts, and to soberly, without emotions, assess the real situation and to understand if there is a threat to the non-proliferation regime," he said.

The United States accuses Iran of secretly developing nuclear weapons under a civilian front, but Iran insists that its nuclear program is only aimed at generating power to meet surging domestic energy demands.

European Union foreign policy chief Javier Solana on Wednesday, reported no breakthrough in his talks with Iran over its disputed nuclear program, while Tehran remained defiant to the United Nations' demand for a suspension of its uranium enrichment activities.

But he said on Friday that the door to negotiations with Iran on its nuclear program "is and will always be open."
