Chinese and Indian troops clash all the time! Most recently is the "Doklam" dispute [1] where they share a border with Bhutan. Last I heard they were literally throwing rocks at each other (not a joke). There's no love lost between the countries, that's for sure.

But I do agree that neither will risk a major confrontation.
