Koshi was signed under Matrika Prasad Koirala. In B.P's account goes Gandaki. It was over 1950 treaty ratification the problem started not about Koshi treaty. But india's bully continued so that petro was cargoed as far as Singapore which was extremly dangerous as far I remember. Mariche had atleast guts to stand against bully but had no longterm plan and Durbaria interference was wide and open. But that history teach us even in the case of no balance due, India will not be ashamed to impose "nakabandi" ever we slightly raise our heads. One of friend is trying to politicise this issue over china by just criticizing but have no solution. If there are willing party don't you think pipelining that 1000 km is an option in longterm. China has plan to make that railway come further in future and India is mulling over to counter (Kantipur). Don't you think we will benefit from both sides and able to raise our head if we have option B. It takes will to find ways. But we are so acustomed to laugh at each other just with discouragement rather than solving problem.
