Presidents Obama and Medvedev announced on 26 March 2010 that they had reached an agreement and signed the treaty in Prague on 8 April 2010.  On the morning of 6 July 2009, the agreement on the text of the joint agreement on the further reduction and limitation of strategic offensive arms was announced, signed by Medvedev and Obama during the US President`s visit to Moscow on the same day. The document listed the intention of both sides to reduce the number of nuclear warheads between 1,500 and 1,675 units and their carrier weapons between 500 and 1100 units.  In February 2020, the Trump administration announced its intention to continue nuclear arms control negotiations with Russia, which had not taken place since Pompeo`s statement that talks on the renewal of New START were beginning.  In July 2020, U.S. and Russian officials met in Vienna for discussions on arms control. The US has invited China to join, but China has made it clear that it will not participate.  Talks between the United States and Russia continued, with the United States proposing a politically binding declaration for Russia to sign. This would involve a draft new treaty that would cover all Russian nuclear weapons and expand New START`s current monitoring and verification regime, with the aim of placing China in a future treaty.  In mid-October, Putin proposed to “extend the current agreement by at least one year without preconditions,” but this offer was rejected by the White House.
Russian officials then accepted a U.S. proposal to freeze nuclear warhead production for a year and extend the contract by one year. Morgan Ortagus, spokesman for the US State Department, said: “We appreciate the Russian Federation`s willingness to make progress on the issue of nuclear arms control. The United States is ready to meet immediately to reach a verifiable agreement.  On May 4, 2009, the United States and Russia began renegotiating START and counted both nuclear warheads and their carrier vehicles as part of a new agreement. While putting aside problematic issues between the two countries, the two sides agreed to reduce the number of warheads they used to about 1,000 to 1,500 each. The United States has said it is open to a Russian proposal to use radars in Azerbaijan and not in Eastern Europe for the proposed missile system.
