In order to participate in the Nuclear Supplies Group (NSG), these factors are taken into account:
Factors taken into account for participation include the following:
- The ability to supply items (including items in transit) covered by the Annexes to Parts 1 and 2 of the NSG Guidelines;
- Adherence to the Guidelines and action in accordance with them;
- Enforcement of a legally based domestic export control system which gives effect to the commitment to act in accordance with the Guidelines;
- Adherence to one or more of the NPT, the Treaties of Pelindaba, Rarotonga, Tlatelolco, Bangkok , Semipalatinsk or an equivalent international nuclear non-proliferation agreement, and full compliance with the obligations of such agreement(s);
- Support of international efforts towards non-proliferation of weapons of mass destruction and of their delivery vehicles.
A country has to adhere to any one of the various international nuclear non-proliferation agreement as one of the criteria.
Regarding France's case, the country's one of the initial 7 participating governments and one of the reasons for the creation of the NSG was to allow non-NPT signatories to join, specifically France at that time.
However, it's unclear whether a non-NPT signatory can still join the NSG now and the group had held a special meeting last year to discuss this, however no consensus was achieved.
On 11 November, the Nuclear Suppliers Group held a special meeting in Vienna to discuss criteria for India’s entry. China continued to block India’s entry into the NSG, citing the need for a non-discriminatory solution to admit non-NPT members.
