This allows China to specifically suppress point targets with their nuclear arsenal, rather than attempting to blanket a given area.

Actually, the same effect could be had by mounting a BHW (Big Honkin' Warhead) on the missile...which they already had done (5 megatons worth). To give you an idea how big that is...drop one on the District of Columbia, and you'll break windows in Baltimore.

Yeah, but those tend to have longer times in flight, cost more and our easily detectable prior to launch. Smaller, more accurate warheads are actually more dangerous.
