The point of disagreement is India's request for April 2020 status, but China believes that it is the year 2000 status.now the issue is india wants everything back to status quo before they started the aggression in 2020. China made a mistake in 1962, and don't to repeat it this time.
japs started the second world war, killed tens of millions of people, they lost, but japs still believe whatever they owned before the war is their property.
India doesn't recognize China's Aksai Chin and South Tibet. So China doesn't recognize India's claims at Ladakh and Arunanchal Pradesh. I call that fair. That so-called China 'Wolf Warrior' diplomacy is pure propaganda BS. What India had done to China is actually far worse than Wolf Warrior diplomacy.
India certainly can do militarily by increasing its cooperation with AUKUS and give them some Naval bases in Andaman Nicobar.It is as simple as India demanding things without having the leverage to force or push China to change its stance.
The way things are going, India should scale back its demands (and their fake news). The only thing that matters is, leverage.
In military they cant do much. Instead, it is China that is rumping up its military presence and readiness.
Economically, the same. Just see the recent data for trade between China and India.
Diplomatically, the same. India wants to make moves but it is constrained by various factors (besides China).
So, I really dont know where India can find something to increase its leverage. My advice, take the Chinese deal to settle the matter, and in return get some concessions from China.
After all, China also doesn't like to have such tensions on its land border, while facing the US on the other side of the country.
So much for "whatever that float your boat", but it's rare to see the said boat made out of wet clay...
