Looking at it from a strategic and lessons learned perspective it makes sense for China to want more LHDs sooner. With OBOR crisscrossing actually and potentially unstable countries and regions it is highly likely that China will both need to face and want to conduct increased MOOTW. While the 071 LPDs are passable for such missions, LHDs with much increased vertical airlift capabilities would be much better. I am not sure if Chinese transport helicopter development is on track to provide a great mid-sized type but overall they are already capable of providing passable helicopters of all types. The LHDs will be handy for actual war as well but their real value would come from MOOTW.
