At current stage India cant offer anything,more than that it is going to be a liability of us,I am strictly opposed of India joining SCO,dont know what exactly promoted GoI to take this new stance.
As many believe here this is not some military cooperation,imagine a military cooperation were India is thy ally of China and Pakistan,all those exercisec performed by SCO are just some counter terror operation's.
SCI is even not relevant as an economic cooperation for us,as only China and Russia are the influential members in it,both of them already present in BRICS and already we have a more than good relation with Russia,the other member in it is Kazakh with whom we also have deep relation's,we even have nuclear trade with them.
SCO will be only act good for us if SCO makes Pakistan allow it's supply root to central asia for us,if eventually that is not happening ,then what good is SCO for us.
