Chinese equity stake in the airport and port will likely result in significant Chinese operation of those ports.
And surely, that's got to have India thinking a little bit - it means that the PLAAF/PLAN now have a potential forward operating base literally in their backyard.
And if China can continue to assert leverage on Sri Lanka, then they might even be able to forward base onto Sri Lanka itself without official argument from Sri Lanka.
I mean, I doubt it, but it seems like a viable play.
