Wishful thinking!
Pakistan has her own geo-political leverage which makes her inyeresting for many countries and India has nothing to do with it so I am sorry to burst your bubble.
Pakistan will be China's energy corridor for a long time to come.
Now that is wishful thinking. Pakistan is not in control of its own territories and the karakoram highway that was blocked by a landslide 3 years ago still remains blocked. That corridor will never occur through Pakistan. Even Gwadar is not ready - having swung from China to Singapore back to China. Now China wants better security for its workers in Pakistan because the place is unsafe even for taller than tallest mountain, sweeter than honey friends. Chinese locomotives are not working and China does not do free projects like USA.
I have heard Pakistani boasts for 45 years. I used to believe them - but I know that they are lies. And in those 45 years, Bangladesh has become a new nation and NWFP and Baluchistan are out of control. The Pakistan army has moved much of its reserves to fight a civil war in the west and the same army now has promised to protect civilian Chinese workers. That is a real laugh because the Pakistan army can't protect Pakistanis. Five soldiets were killed today by the way.
So all this energy corridor-shenergy corridor stuff can be forgotten. Just bluster. Not even wet dreams.
