“Nuclear-weapon states should negotiate and conclude a treaty on no-first-use of nuclear weapons against each other or make a political statement in this regard,” Sun said.
China and India are currently the only two nuclear powers to formally maintain a no first use policy. Russia and the United States have the world’s biggest nuclear arsenals.
How so, that is exactly inline with “no first use”.
How could “we will use every weapon in our arsenal” possibly be interpreted to mean “no first use”?
Nuclear weapons would not just be used to respond to nuclear threats, if that’s your assumption.
