New Delhi, March 1 :     India and Pakistan are to coordinate their responses to the United States on issues raised by Washington in its nuclear dialogue with New Delhi and Islamabad since last May?s nuclear tests, notwithstanding the tough weekend statements on Kashmir on both sides of the border. This is one of the unpublicised results of the summit between the Indian and Pakistani Prime Ministers in Lahore last month. At the same time, India has unilaterally decided to provide the US and several other countries advance notification in respect of ballistic missile flight tests. Confirming this confidence- building initiative, official sources said New Delhi would not be averse to concluding bilateral agreements with key countries in this regard. Indo-Pakistan coordination on dealing with the US, worked out between the official delegations which accompanied Atal Behari Vajpayee and Nawaz Sharif to Lahore, will focus on the commonalities in their approach to the Comprehensive Test Ban Treaty (CTBT) and the Fissile Material Cut-off Treaty (FMCT). Official sources pointed out that there was much in common between the Indian and Pakistani conditions for becoming signatories to CTBT. The Indian stand, articulated by Vajpayee at the UN last year and reiterated down the line by ministers and officials, insists that New Delhi will become a party to CTBT in a ?positive atmosphere?. Pakistan, on the other hand, says it is willing to sign up provided there is ?no coercion? on Islamabad to do so. In effect, these mean the same. There is also a lot in common in the way India and Pakistan view the FMCT negotiations due to commence in Geneva shortly. Talks between disarmament officials of India and Pakistan in the run-up to the Lahore summit not only identified these common strands, but also explored the possibilities of harnessing such commonality of approach. These sources reiterated that India had given no assurance to the US on signing the CTBT. On the contrary, they spelt out the minimum that the US is required to do before progress can be made on India?s accession to the treaty. These minimum conditions are an end to restrictions on multilateral lending to India and a pruning of the entities list announced by the US last year. Official sources said these steps could create a ?positive atmosphere? which the government is seeking in order not to stand in the way of CTBT?s entry into force as planned by the end of this year. If the US administration were to take note of the need to turn public opinion in this country in favour of CTBT, then they would also contribute to creating a positive atmosphere in which India could accede to the treaty. Official sources reiterated that India had no intention of wrecking the global non-proliferation regime, of which CTBT is a part, but expressed New Delhi?s inability to move forward on the treaty as long as public opinion in this country remained opposed to CTBT.
