I'm more interested in what PLAN is trying to do here.well thougth Japanese claims it DD, it doesent mena that it wouldnt field missiles. In japanese system DDG means AAW ship and other destroyers and frigates gets the DD prefix. It has harpoon, ASROC, and sea sparrow (and as it has the VSL system, it will be easy to fit ESSM if Japanese chooses it to become their new SAM)
But inspite its similar weigth, the japanese ship is still fully fletched ASW unit, part of 50 years or so contiunity and 054A migth just be the first one earning that title in PLAN.
I don't believe 054A is at the level of Taknami in terms of ASW capability, but it is a level that 054A needs to evolve into to give PLAN the kind of ASW capability needed to protect future carrier groups.
Anyhow, as I said, 054A is still getting built, let's see what it turns into. Can't wait for new photos to come out. If HQ-16 really has the range of VLS shtil (or even greater), then it indicates PLAN is also giving 054A the role of area defence.
