Its just the standard scaremongering news reporting.
America had over 70 AEGIS destroyers/cruisers, with 11 super aircraft carriers (90 aircrafts onboard) that forms into battle groups (CVBG) - with more than half a centuries of experience operating it.
China is only taking baby steps, with TWO "Aegis-like" destroyer (052c), and *maybe* 2 small aircraft carriers (15-30 aircrafts onboard). Its destroyers can't even protect its own aircraft carriers! (1 each?! I doubt it can even cover 1 side)
It needs to produce at least 8 more 052c (5 each) to be able to complete the 2 battle groups strategy (and maybe 2 SSNs covering the sea beneath)
