Pakistaninfo-icon's Foreign Office has rejected a new formula for evaluation of the candidature of non-Non-Proliferation Treaty (NPT) states for the Nuclear Suppliers Groups (NSG) membership as "discriminatory" and "unhelpful".

At the weekly mediainfo-icon briefing on Thursday, Foreign Office spokesman Nafees Zakaria said: "This would be clearly discriminatory and would contribute nothing in terms of furthering the non-proliferation objectives of the NSG," Dawn News reported.

Ambassador Rafael Mariano Grossi of Argentinainfo-icon had been appointed as a facilitator for discussions among the NSG members after Seoul plenary meeting of the 48-nation nuclear trade cartel ended in a stalemate over membership applications from Indiainfo-icon and Pakistan.

The deadlock persisted at the extraordinary plenary held in Vienna last month.

Ambassador Grossi this month submitted a two-page revised document to the NSG member countries containing a nine-point proposal on considering the applications of India and Pakistan, both of whom are non-NPT countries.

The NSG members last week again met in Vienna for discussing the document called "revised version of a draft 'Exchange of Notes' for Non-NPT applicants".

Pakistan, Zakaria said, continues to emphasise the imperative for a non-discriminatory criteria-based approach for the NSG membership of non-NPT states in a non-discriminatory manner, Dawn News said.

"Such a criteria-based approach will further the non-proliferation objective of the NSG as well as the objective of strategic stability in South Asiainfo-icon," he said.

The spokesman reminded the NSG members of "the heavy responsibility" they bore with respect to admission of non-NPT states.

"It is important for the credibility of the NSG and the future of the non-proliferation regime that the NSG be seen as a rule-based organisation rather than a grouping which is driven by commercial and political considerations that trump its non-proliferation objectives," he maintained.
