I think this has to due to Vietnam expanding its Gray Zone Tactic, which is basically like fighting without using weapons but by interpreting and blending the laws.

Yeah, this feeds to my previous point. These islands are multi-purpose and are probably used for both civilian and military uses. This makes sense as Vietnam is between the point of East Asia and Southeast Asia. They're probably trying to monopolize or keep the stability of this canal.

The Philippines is also in the same area as Vietnam, but not much is happening.

It also makes me kinda doubt if this development is worth it. Just one of these islands is practically the price of an aircraft carrier or a couple of destroyers.
