Medvedev praised the condition of the United States to join the start-3 other countries

The condition of the States acceding to the start-3 in other countries makes the extension of the agreement almost non-viable, said Deputy head of the security Council of the Russian Federation Dmitry Medvedev.

The United States insists on bringing China to the Russian-American talks on strategic renewal of the contract start-3, China says it is not interested in that.

Start-3 came into force in 2011. Under this agreement, the parties undertake to limit its Armed forces 700 carriers of nuclear weapons to 1,550 warheads and 800 launchers.

Start-3 remains the only current agreement between Russia and the USA on the limitation of armaments. The agreement expires in February 2021. Russia has repeatedly urged the United States to prolong it, but so far the us administration has not announced whether Washington intends to do it.
