UNITED NATIONS - With obviously US-India nuclear deals in mind, a senior Pakistani diplomat told the United Nations on Tuesday that discriminatory nuclear cooperation agreements that some powerful states had entered into had changed the strategic environment of South Asian region, accentuating Pakistans security concerns. In a speech to the General Assemblys Disarmament and International Security Committee, Ambassador Zamir Akram, said that Pakistan would continue to block the start of talks on a US-backed treaty to ban production of fissile material used as fuel for nuclear weapons because it was prejudicial to its legitimate security interests. Over the past few years, some powerful countries, in pursuit of their commercial interests as well as dubious notions of balance of power, have embarked upon an unfettered and discriminatory nuclear cooperation arrangement in gross violation of their international commitments, Ambassador Zamir Akram said. This has accentuated our security concerns as such nuclear cooperation shall further widen the asymmetry in stockpiles in our region. Ambassador Akram, who is Pakistans permanent representative to the UNs European offices in Geneva, did not name any country in his speech, but he was clearly aiming at the United States and other major nuclear powers pressuring Islamabad allow the talks to go ahead. Also, it is well known that India has a larger stock of fissile material than Pakistan does, and a greater capacity to build warheads. Thus, an FMCT (Fissile Material Cut-off Treaty) that purports only to ban future production of fissile material, will permanently freeze a strategic disadvantage for Pakistan, and is, therefore, unacceptable to us, the senior Pakistani diplomat said. Clearly it is not through choice but necessity that Pakistan is opposed to negotiations on an FMCT, he added. Since January, Pakistan has been blocking the launching of negotiations on the proposed treaty at the Conference on Disarmament in Geneva on the ground that it prejudicial to its national security interests. With the introduction of the treaty into the agenda of the Conference in 1994, Ambassador Akram said Pakistan had called attention to the fact that a treaty to cut off future production of fissile material would freeze the existing asymmetries in fissile material stockpiles, which would be detrimental for its national security. Accordingly, Pakistan had been advocating a treaty that not only banned future production, but also aimed at reducing existing stockpiles of fissile material. A growing asymmetry in military capabilities between major powers and medium and small states had further increased insecurity among states, and in crucial regions, the pursuit of great power politics had destabilised tenuous regional balance, Zamir Akram told delegates from around the world. The Pakistani delegate asserted, as the committees general debate came to a close, that some states had been denied the right to peaceful nuclear cooperation, while others were helped in promoting unsafeguarded nuclear programmes and building and upgrading strategic weapon systems, including anti-ballistic ones, thereby accelerating vertical nuclear proliferation. He pointed out that the current hiatus in the Conference on Disarmament was not unprecedented. That body had not undertaken negotiations for any multilateral instrument since it last concluded the Comprehensive Nuclear-Test-Ban Treaty (CTBT) in 1995. He said that a growing asymmetry in military capabilities between major Powers and medium and small States had further increased insecurity among States. In crucial regions, the pursuit of great power politics had destabilised tenuous regional balance. Attempts to forge a new consensus on arms control and disarmament required the convening of a fourth special session of the General Assembly devoted to disarmament. That alone could ensure genuine and complete ownership of the outcome by all States. Pakistan, he added, was also dismayed by arguments from some States that the United Nations disarmament machinery, in particular the Conference on Disarmament, had become dysfunctional, owing to its rule of procedure, he said. The United Nations disarmament machinery and the Conference on Disarmament, in particular, were not handmaiden to the whims of the major Powers or a device to confer legitimacy on their pursuit of discriminatory policies, the Pakistan delegate said.
