EDCA bases is a money grab that Marcos did right. He offered up some decrepit bases (or sometimes just a patch of jungle) to give the impression that he is on board with the US and puts China on notice. For that, the US is spending upwards of $100 million to refurbish them which I think is not enough. For example, one of EDCA bases is naval bases Narciso del Rosario on Balabac island across the Balabac strait from Borneo. And it is said to be one of the two bases, along with Antonio Bautista airbase, that checkmates the heavily fortified Spratly Island military base. It currently has an almost completed runway but no naval facilities, so it will be another couple of more years and many more millions of dollars for it to be proper naval station. Marcos wants to open up southern and eastern Philippines for development, and EDCA money is the way he goes about it. While EDCA is a good talking point for both USA and Philippines; their strategic significance vis-a-vis China is, IMHO, tenuous at best. I believe those bases are there so in case Taiwan is lost, there are still 9 US bases in the strategic Southern China Sea area to keep up the facade of US relevance in that part of the world.EDCA is certainly not insignificant, progress on its implementation has been modest so far
