Western propaganda and lie machine is more effective and well run than PRC's and India's put together (that's saying something!). Some things are said just for the purposes of seeing reactions or duping their own internal factions. There's a long history of mastering psychological warfare. I would ignore this "information". You guys have speculated on several possible purposes already. There are dozens more.
Thinking about it from a China only perspective, I think the news doesn't hold merit unless the newest 055, submarines, and carrier is determined by PLAN to be of the highest capability and enough to deter or go to war with the US in regional waters. This isn't true no matter how good anyone thinks of these things and certainly the subs (not counting 095 and 096) and carrier are weaker links than something like the 055. Even then, it is expected to get upgraded weapons and full IEP with railgun. So PLAN certainly will still want numbers and if somehow there's truth to the budget not being enough at around a measly 2% GDP (PRC can more than double this to reach what most military countries spend), the army can suffer because airforce, navy, and strategic improvements take priority. Cutting the navy budget now is exactly the opposite of what they need and probably will be doing.
