Does the PLAN plan to build enough 052Ds to match the Arleigh Burkes in either hulls or VLS count?
No. This is too simplicitic in thinking.
Acquisition of DDGs is more than trying to match your opponent's ship numbers. Arleigh Burkes can be dealt with by other means like land based anti-ship missiles, air launch missiles etc. also, very unlikely US navy will deploy all its AB DDGs to seas facing China. USN will need them elsewhere like East Pacific, both side of Atlantics, Indian Ocean and the Mediterranean.
More important is how many DDGs are required to escort aircraft carriers, landing ships, convoy escorts, ship based air defense for coastal cities like Tianjin, Beijing, Shanghai, Shenzhen etc, and anti-submarine warfare against the large combined number of submarines from AUKUS, Japan and South Korea, and against possible NATO's adventure into China's backyard.
However, it is correct to say that PLAN's build up is against very real threat from US and its allies. It will be 5 dimensional war involving more than just ships vs ships.
