Washington, Oct. 16 The White House of the United States rejected Russia’s proposal to unconditionally extend the START treaty, which expires next year, for at least one year. U.S. president’s national security affairs assistant O’Brien said in a statement on the same day that Russian President Putin’s proposal to extend the START treaty without limiting the number of nuclear warheads was “unworkable”. The United States proposes to extend the Treaty for one year, but the two countries must limit the number of their nuclear warheads. He also said he hoped that Russia would reassess its position before the arms race. According to a statement on the Kremlin website, Putin convened the standing members of the Russian Federation Security Council on the 16th to discuss the issue of the new strategic arms reduction treaty. Putin proposed an unconditional extension of the Treaty for at least one year. He said that the extension of the treaty aims to gain opportunities for detailed consultation on relevant issues and prevent Russia and the United States, as well as all countries in the world that want to maintain strategic stability, from losing the basic documents in this field. According to the analysis, the US proposal to limit the number of nuclear warheads is aimed at limiting Russia’s tactical nuclear weapons. Russian Deputy Foreign Minister rybuyakov has previously said that the relevant US position is unacceptable to Russia. The United States and Russia signed the new strategic arms reduction treaty in 2010, which aims to limit the number of nuclear warheads and delivery vehicles deployed by the two countries. After the Sino Missile Treaty between the United States and Russia expired in 2019, the new strategic arms reduction treaty has become the only arms control treaty between the two countries. The treaty will expire in February 2021, but the validity period of the Treaty can be extended for up to five years after negotiation between the two countries. In order to discuss issues related to the extension of the new START treaty, representatives of the United States and Russia began to hold several rounds of dialogue and negotiation in June this year, but no substantial progress has been made.
