Not even close. It carries about 200 low yield warheads. Not even enough for 1 each for 1/3rd of the cities in China if you could spread them out that far. There have been over 500 atmospheric tests, many with vastly higher yield and fallout, the biggest tests had yields equivalent to all 200 warheads combined.

One could strike a huge blow to China's capability to carry on war by destroying many of its large ports.
