The road always existed. It is just that the alignment was not great but the tanks could move. The problem was during the summers when the Shyok used to get flooded. There was no problem during winters because the river would freeze. India initially began with three regiments of 46 tanks each positioned at vantage points at the SSN. This number has been bolstered to a very comfortable level.

For the Chinese, the infrastructure arms race in the border region has led to repeated Indian incursions and changes to the status quo.
Otherwise, all the things China fought for in the 1962 war would have been in vain according to Yun Sun
