On 14th of this month PLAN sent two 071 and circled around to the east side of Taiwan and conducted simulated landing operations against Hualian which hosts major ROCAF and ROCN bases.
I'm of the opinion that this sort of thing is exactly what 071 and 075 should be used for. They shouldn't be part of the landing force crossing the strait but rather should circle around to the lightly defended rear area that is Taiwan's eastern seaboard and deploy vertically and quickly knock out key locations like this.
By running this sort of exercise when the time comes ROC will be faced with the decision of either doing what they are doing now and keep the vast majority of their land forces on the west side and leave their rear area lightly defended and vulnerable to this sort of attack, or alternatively transfer some of their forces to the east side and leave their western defence weaker than they already are.
The geography of the eastern side of the island and the greater vulnerability of the eastern side of the island in general, means such operations would be require substantial air and naval escort/support and the forces that they deploy would be lacking in depth and persistence.
In context of a proper high intensity invasion operation, I'm doubtful whether large amphibious ships would best be used in that kind of risky, low yield mission rather than simply contributing their large amphibious sea lift capability to a direct frontal assault.
Or, putting it another way, small scale surgical operations on the eastern seaboard could be conducted by amphibious assault ships but they can also be conducted to an extent by air and missile strikes.
However, there is no substitute to having the sea lift capability to conduct a rapid amphibious assault to establish and secure a beachhead for follow on forces. I imagine that only once the amphibious (and joint) capabilities needed to guarantee that key prerequisite, would they consider conducting more fancy tasks like raids on the eastern side of the island.
