But as you said yourself Myanmar’s infrastructure is lacking and Myanmar isn’t exactly known for being the most politically stable nation. It’s gonna take a large investment to see it through.
Well, I think now is not the right time. Many of the CMEC projects are so far from completing that you don't need to start a base there yet.
However, there is this constant rumbling
And I would say that if you put a decent sized base in area around Kyaukphyu (doesn't have to be there exactly) & not right next to the Indian base. It will be close enough to Yunnan where Chinese bombers can take off to assist and same with tankers and such. That I don't think Indians can do much other than complain. And I think it would be entirely defendable from US naval attacks.
