If Chinese are planning to make such huge investments, then Pakistan will have to put up with everything which Chinese demands to protect their investments, I guess Pakistan's personal grudges against India has no place in Trade and Business.
India wants to be treated at par with U.S. / China and Pakistan wants to be treated at par with India for all bilateral agreements.
So whats the big deal if Afghanis are demanding the same.
I guess Indian Foreign office has a 'Wait & Watch' policy towards its western neighbor. It is waiting for either its COAS to take control of the Country officially or PM Sharif could his assert authority (very unlikely) in decision making regarding settlement of Kashmir Issue.
