Well China doesn't need global reach like the US (where all our enemies are on the other side of the ocean). If you look at the recent history of armed conflicts involving the PRC all their conflicts have been with their neighbors (India, Vietnam, USSR, Taiwan) except for the Korean war (which was still fought on the Asian mainland).
China's naval strategy appears to be focused on two types of conflict; overwhelm and destroy a neighbors navy or deny US forces access to Asia without stating another world war.
The first strategy is strait forward conventional tactics. While the second strategy focus more on deterrence using land based bombers, subs and massive numbers of open ocean mines.
