I can't believe the nonsense I am reading, another one goes on the ignore list then.
Anyone who think India can mount any sort of blockade on China simply does not grasp the most basic fundamentals of how international trade works.
Chinese flagged ships do not exclusively carry cargo bound to/from China, and a great bulk of China bound cargo is carried on foreign flagged ships.
Even if we ignore the giant question mark of whether India actually has the military capability to enforce a blockade of shipping in the Indian Ocean in the face of PLA opposition, the simple reality of how world trade works means that for India to have any chance of trying to disrupt Chinese trade, they would have to effectively cut off
ALL trade through the Indian Ocean.
There is also the inconvenient fact that trade is a two-way street. India attacking Chinese shipping won't just upset China, it will also upset the countries who bought and paid for the goods on those ships, and who's economic and social welfare depend on that trade.
Then it won't be a simple matter of India vs China, it will be India vs the rest of the world.
For a blockade to work, you either need massive political, financial and military capabilities far beyond what India could dream of aspiring to; or you need geographical chock points.
And no, places like the Indian Ocean or Malacca Strait don't work well as chock points against China because of how far away they are from China and how much international trade goes through there.
Unless you want to stop world wide free trade, and have the military power and the political will to fight the rest of the world to do it, you just can't mount an effective blockade of China through those far away chock points.
That is why the US spent all that time and political capital trying to stir things up in the South China Sea - because that would be an ideal place to mount such a blockade against Chinese seaborne trade.
The USN already owns the Indian Ocean, if it was such a simple matter to blockade China through there, why would they have bothered with the SCS? Conversely, if even the USN is looking at the SCS for a far better way to try and threaten Chinese seaborne trade, what makes anyone think the far punier Indian Navy can do any better in the Indian Ocean?
If anything, Indian attempts to threaten Chinese seaborne trade in the Indian Ocaen would actually only serve to give the PLAN the perfect pretext and opportunity to enforce a blockade of Indian seaborne trade.
All the PLAN needs to do is deploy its subs to covertly lay minefields within 200km (not a set-in-stone figure, and can be more or less depending on need and circumstance) of Indian ports. Declare that as necessary to protect international free trade from Indian attacks, and civilian shipping to India simply stops.
International shipping can use the Indian Ocean without disruption by simply staying 200km from the Indian coast so international ire would be limited. Especially since Indian world trade is so tiny in comparison to China.
However, no insurance company would touch any ship wanting to dock at an Indian port because of the mine threat, and without insurance, no skipper would agree to take a freight job to India, especially with a very real mine threat.
