What is this NSG (Nuclear Suppliers Group) and why India wants its membership

There has been lot going on about India's efforts for being the member of NSG. Prime Minister Narendra Modi has visited various nation and meet leader of NSG countries for their agreement on India's induction in NSG. So what's this NSG and why India is so keen on becoming its member, let us look at the whole scenario from the start.

After India detonated its first atom bomb in 1974, the nuclear weapon carrying states come together to found NSG i.e. Nuclear Supplier Group, with the aim of ensuring non-proliferation of nuclear weapons and nuclear technology. India saw it as a tactic to keep India away from access to sophisticated technology. Initially NSG had seven participating governments: Canada, West Germany, France, Japan, the Soviet Union, the United Kingdom, and the United States. These were also the member of NPT (Nuclear Non-proliferation Treaty) except France. In 1976-77, participation was expanded to fifteen other nation and later on many other nation was induced in NSG including China in 2004, and up till now in 2016, 48 countries are participating member of NSG. So what is the problem than why India did not become its member.

Member of NSG

India is kept away from NSG, mainly on the basis that it is not the signatory of NPT. India can never sign NPT as it is against the ethics of India foreign policy. Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, and to further the goal of achieving nuclear disarmament and general and complete disarmament. NPT divides its member nation into two category: nuclear-weapon states (NWS)—consisting of the United States, Russia, China, France, and the United Kingdom—and non-nuclear-weapon states (NNWS). According to NPT the NWS have committed to complete nuclear disarmament while the NNWS have agreed to let go of developing or acquiring nuclear weapons. If India have to sign NPT it will have to let go all its nuclear arsenal, which is not right thing to do when Pakistan is also carrying nuclear weapons. Main player in keeping India away from NPT is China, as it don't want India to advance in nuclear technology and commerce, because it will threatened its position in South-Asia and disturb the power equation. So all the recent visits of Prime Minister are mainly to gain a common consensus of NSG member countries on India's induction in NSG.

Why India wants to be NSG member:

1. Everything India owns in nuclear technology is indigenously developed, membership in NSG will open the doors of possibility for India to get its hand on more sophisticated technology and further development in medicinal purposes of nuclear science and power plants. 
2. It will help India to reduce its dependence on the depleting fossil  fuels reservoir and will help India to strengthen its future power needs of clean energy. Having the ability to offer its own nuclear power plants to the world means spawning of an entire nuclear industry and related technology development. This could give the Make in India programme a big boost. 
3. Membership in NSG will open up the nuclear commerce for India. India can export and import the nuclear technology. With access to latest technology, India can commercialize the production of nuclear power equipment.
4.  Once Inducted in the NSG India can block Pakistan from its membership into the group as entry into the group is by consensus only.
