"Some initiatives in terms of reducing nuclear potential are welcome, but in this case, it is very difficult to [react to] common phrases. The intentions are good, but we would like to know the details, [in particular] what President Trump means [by his proposals]", Peskov said.
According to the Kremlin's spokesman, US experts did not discuss such a topic with their Russian colleagues.
In early April, Trump said that the United States, Russia and China should stop spending on weapons and invest in long-term peace instead.
At the same time, the Russian government stated that the US move jeopardised New Strategic Arms Reduction Treaty (New START) which limits the number of nuclear warheads the superpowers can deploy. The deal is set to expire in 2021, however, it can be extended for another five years, should the sides choose.
