"I wish ... that the country (US. - RT ) be in START III ... with our opponents, in particular, with Russia," RIA Novosti Heiten quotes.

He expressed the hope that US State Department officials would meet with their colleagues from Russia to discuss the START III treaty.

According to him, “Russia and China are talking about hypersonic weapons as part of their future strategic deterrent force, that is, the nuclear hypersonic potential.”

“We have no plan for using hypersonic weapons in our nuclear deterrent,” Heiten added.

In March, the Russian ambassador to the US, Anatoly Antonov, said that there is still a possibility to extend the effect of START III.
