The Bulletin of the Atomic Scientists reported that China appears to have four new nuclear-tipped ballistic missiles.

China now possesses 240 nuclear weapons with 40 missiles capable of striking the U.S. mainland.

Authors Hans Kristensen and Robert Norris added that China has encountered difficulties in developing a submarine-based nuclear platform and is spending considerable resources to disperse and hide its land-based missiles.
