Russian Foreign Minister Sergei Lavrov on Saturday had a telephone discussion with U.S. Secretary of State Condoleezza Rice on the coming meeting of diplomatic quartet and the Iranian nuclear issue.

The conversation "focused on the search for a diplomatic solution to the Iranian nuclear problem," the Russian Foreign Ministry said in a statement

In Washington, a spokeswoman for the U.S. State Department confirmed that Rice and Lavrov talked about "a number of issues regarding the quartet" and the Monday meeting of five permanent members of the UN Security Council on Iran.

The quartet, consisting of the United Nations, the United States, the European Union and Russia, is seeking to bring a solution to the Israeli-Palestinian conflict. They are due to meet in New York on Tuesday.

Before the telephone conversation, Russia stuck to its demand on Saturday that the draft resolution on Iran submitted by European countries to the UN Security Council "needs adjustment."

Russian Deputy Foreign Minister Sergei Kislyak was quoted by Interfax new agency as saying "It is too early to say which changes should be made to the draft resolution to satisfy Russia."

France and Britain, backed by the United States, introduced on Wednesday the draft resolution to the UN Security Council, demanding Iran suspend all enrichment activities immediately or face possible sanctions.
