As a matter of fact, China is speeding up its nuclear arsenal. Right now, the estimation is that China possesses about 350 nuclear warheads, nuclear bombs, which is not enough to present deterrence for the other powers to hold back with their retaliation, but China is speeding up its build-up of its nuclear arsenal.
What is worrisome here is the fact that Mr. Putin's reference to nuclear weapons in Ukraine seems to be having some effect on more forceful assistance from the western camp to Ukraine. Maybe Mr. Xi Jinping would see something that he can take advantage of with nuclear power. As a matter of fact, in his 20th Communist Party Congress, which took place in October of last year, he specifically mentioned a building up of nuclear-powered strategic weapons for China to be able to use in wartime, so I think that this is something very alarming to us.
