Ships take years to build and commission, your outline will take over a couple decades, and we have'nt got to the funding part yet. There is simply no money for this kind of shopping spree. And I don't think the Russians would even entertain the idea of PLAN outnumber the RN Pacific fleet in terms of Sovermenny destroyers.
Nuclear Subs and Carriers take even longer to construct, you start building them now if you plan on using them in 10 years time.
Sorry this is not a game and China simply does'nt have the money.
