Now India wants to be the member of NSG and India’s pending application for entry into NSG will come up for consideration in June 2016.
But according to the rule of NSG, decision of inducting new member would be taken through consensus only i.e. every member should agree. It means even one member can thwart the entry of any country into the group.
China is opposed to India’s membership in NSG citing that India has not signed NPT.
Apart from this China has also encouraged Pakistan to apply for NSG membership so as to link India’s entry with that of Pakistan.
Pakistan fears that if India became member of NSG than it will not be able to become its member because as decision to induct new member is taken on consensus; India will never support membership for Pakistan. It is one of the reason Pakistan is opposing India’s membership.
