Though it is surprising that they are so advanced
You are surprised? I knew they were getting close; they already have a manned space program that is progressing at roughly the same rate as ours did in the Space Race, they were working on this for a long time, and they do make fairly good missiles. Besides, they are hardly the first people to develop something along these lines; while the Pershing II wasn't specifically designed to go after moving ships, it did have radar guidance on a maneuverable reentry vehicle back in the '80s. It proved it could be done, the Chinese just extended the scope of the concept.
