If you look at the map ghaghra & kosi join ganga only at the fag end of the course before it runs of into BD. All these rivers start as streams and gain water as they move along. Even if China dams it in their territory the shortfall will not be that much big.
Ghagra for its major part gains more water in nepal. Kosi gets only half of its water from nepal.
The end of a river is where it is at it's strongest, so hence any work upstream will drastically affect you and the Ganges, this is how rivers work. Both rivers gain their momentum in Tibet, whose glacial waters are crucial especially with falling rain days from the monsoons.
In fact river kosi is a more of a headache than any thing else. What holds good for India in kashmir holds good for China as well, damming kosi is not an easy task. In fact building a dam is welcome thing, river kosi has changed path so many times in history that only after Independence it seems to stick to nearby places.
It's not a headache it's a tributary which feeds the Ganga....Which is now more important than ever. The Kosi is quite stable now, it hasn't changed course in a while, but yes damming it or doing something else is not easy. I'm just writing about options available.
As I said China can dam bhramaputra but that will affect NE but not to that extent to be a big liability for the country as a whole. More ever it will also drag BD into it.
China has multiple options at its disposal, as for BD they don't care if they see their closest ally being strangled by India for water....
