Islamabad, Jan 30 (TIWN) In a sensational observation which will have far reaching ramifications particularly in the highly volatile nuclear armed South Asian neighbourhood, Pakistan has said that it does not consider itself bound to any obligation preserved under the Treaty on the Prohibition of Nuclear Weapons as it was not part of its negotiations.

Though hailed as a historic step by several nations, the treaty was opposed by the world's nuclear-armed countries, including the US, China, Russia, the UK and India. Japan also didn't support the pact.

The treaty, which was adopted in July 2017, was "negotiated outside the established UN disarmament negotiating forums," Pakistan's Foreign Office said in a statement.

“Accordingly, Pakistan does not consider itself bound by any of the obligations enshrined in this treaty. Pakistan stresses that this treaty neither forms a part of, nor contributes to the development of customary international law in any manner,” it said.
