The 075 LHD is a lot more versatile ship than the 071 LPD for PLAN, which lacks forward naval bases, and especially at times when large scale amphibious operation (that requires multiple LHDs/LPDs working together) far from home is unlikely, and MOOTW is important. They could build as many 075 as the 071, or more.
They need to keep up the production of helicopters nonetheless to make full use of it. Also programs for the equivalent of V-22, CH-53 and F-35B would immensely boost both the capability and versatility of these LPDs, there is great potential in them if these programs actually exist.
