"Our position is very clear. We believe that there are absolutely no reasons and conditions for conducting trilateral disarmament negotiations with the participation of the United States and Russia. China will not take part in them. We have already said that the United States is constantly trying to involve China in this deal", Geng said at a briefing.
According to him, the United States bears a special responsibility since it possesses the largest and most modern nuclear arsenal.
"The United States should respond to Russia's calls for an extension of the New START [Strategic Arms Reduction Treaty] as well as reduce its huge nuclear arsenal in order to create conditions for other nuclear countries to enter these negotiations", the spokesman added.
Since the termination of the Intermediate-Range Nuclear Forces Treaty between Washington and Moscow in August, US President Donald Trump has repeatedly mentioned the possibility of concluding a new arms control treaty that includes Russia and China.
The New START is the last remaining arms control treaty in force between Russia and the United States. It stipulates that the number of strategic nuclear missiles launchers must be cut by half and limits the number of deployed strategic nuclear warheads to 1,550. The agreement is set to expire in February 2021 and the US has not so far announced plans to extend it, while Russia has repeatedly stressed that it was ready for a dialogue on the future of the treaty.
