Moscow, Oct. 20, the Russian Foreign Ministry issued a statement on its official website on 20 October, saying that Russia is willing to jointly undertake the obligation of freezing the number of nuclear warheads with the United States, in order to get the response of the United States to Russia’s proposal to extend the START treaty for one year. Russian President Vladimir Putin proposed on the 16th that the new START treaty, which will expire next year, be extended unconditionally for at least one year, the statement said. In this regard, the Russian side has only seen some comments from the US side on individual social networking sites, but has not received an official reply from the US side to the Russian proposal. The statement said that Russia is ready to make a joint political commitment with the United States to freeze the number of nuclear warheads on both sides during the extension period. If the United States accepts this plan, the two sides can carry out a series of negotiations on future nuclear arms control within the extension period of the new strategic arms reduction treaty. Putin proposed to the United States to extend the START treaty unconditionally for at least one year. On the same day, U.S. president’s national security affairs assistant O’Brien said that Russia’s proposal to extend the START treaty without limiting the number of nuclear warheads is “unworkable”. The United States proposes to extend the Treaty for one year, but the two countries must limit the number of their own nuclear warheads. The United States and Russia signed the new strategic arms reduction treaty in 2010 to limit the number of nuclear warheads and delivery vehicles deployed by the two countries. The treaty will expire in February 2021. In order to discuss issues related to the extension of the treaty, representatives of the United States and Russia began to hold several rounds of dialogue and negotiation in June this year, but no substantive progress has been made.
