Russian President Dmitry Medvedev held a telephone conversation with his U.S. counterpart Barack Obama on Tuesday, concerning their forthcoming Moscow summit, said the Kremlin website.

A statement posted on the website said the two presidents discussed via phone in detail "of nearly every point on their agenda and schedule in Moscow."

"In particular, the presidents placed significant emphasis on the topic of reducing strategic nuclear weapons," it said.

"They discussed various aspects of the nuclear weapons issue, in accordance with the positions that have been reached by the two countries' teams of negotiators. The presidents agreed to instruct Russian and U.S. negotiators to work actively with the goal of reaching concrete results," said the statement.

Medvedev and Obama, at their first meeting in London early April, agreed to negotiate a replacement for the Strategic Arms Reduction Treaty (START I) by the end of this year when the treaty is due to expire.

The two leaders also expressed certainty in the telephone conversation that the upcoming summit "will provide great momentum and create a more productive atmosphere for bilateral relations, as well as allowing the presidents to better get to know one another."

Obama is scheduled to pay a working visit to Russia on July 6-8.

Since Obama took office, Russia and the United States have been actively engaged in efforts to reset ties strained during the previous U.S. administration under George W. Bush.
