Right on. If a river of oil is discovered flowing from India into China. The Indian government certainly would try to pump out as much oil as possible it reaches China. As a commodity like oil and a source of hydro-electric power, water is indeed a zero-sum game. Of course, no one should be against the idea that water's other usage could be win-win. So far, the author is not able to shed any light on any win-win possibility.
I am not sure this is time for China to transit from trade power to financial power. A developing economy with "90 trillion renminbi in banking assets and $3.2 trillion in foreign-exchange reserves" is unprecedented and somewhat troubling.
"To paraphrase Winston Churchill, elections are the worst way to select a political leader, save for all other methods that have been tried – and nowhere more so than in America." I find it odd that people has to quote Churchill who is not any kind of god to reassure himself and the readers that western democracy is a better system.
