re: PLAN Type 071 LPD & its Landing Craft
The PLAN does not need anything as large or capable as the 071 if their main focus is Taiwan.
The 071s are part of the PLAN's blue water project to build up its power projection capabilities. The idea is being able to evacuate Chinese nationals and/or be ready to deploy small expeditionary forces to safeguard Chinese lives and interests, most likely in places like Africa.
The PLAN does not need, nor want the capability to launch a full scale invasion of another country half way across the world. As such, helo carrier would be much more useful, and I can easily see the PLAN shifting the building emphasis to a helo carrier after they have built up a basic core of LPDs to have the option of getting heavy armour into any battlefront within reach of a beach.
I think their recent experiences with anti-piracy as well as their evacuation mission in Libya has more than reinforced the flexibility a good LPH would offer naval planners.
With the Varyag potentially being the PLAN's only operational carrier maybe for as long as the next 10 years, LPHs become even more important as they can act as mini carriers in almost all ways a real carrier can in everything except combat missions. But since 99% of the PLAN's foreseeable future missions would not be actual combat missions, the limitations of the LPH is less noticeable in actual likely missions.
