Yeah, sure, the jobs of masters.
String of pearls is there, so China can choke Indian navy, in case India becomes an unnecessary and irritating thorn in Chinese side.
They can plug the thorn out easily.
Dream about blocking Chinese Shipping lanes, From the mouth of Persian Gulf, i.e. Iranian Ports and shores to Gawadar, to Sri Lanka and then Burma's coast and ports to the strait of Malaca. Where could India choke China!!
The only trouble for China is the Strait, it has to deal with different countries in the Strait.
For that I am certain China already have an strategy. This is something known to all the military planners in the world.
India is just an unnecessary evil , which none of its neighbours like or happy with.
Don't rely on YANKS. They are not coming.
