NEW DELHI/ISLAMABAD (Agencies) - President Asif Ali Zardari Saturday said Pakistan was against the use of nuclear weapons and urged India to sign a nuclear-free South Asia treaty. He announced no first use of nuclear weapons and called for scaling up trade and visa-free travel between the two countries. He was addressing the concluding session of the two-day Leadership Summit organised by the Hindustan Times here via videoconferencing from Isla-mabad. The President said, "I am against nuclear warfare altogether. Most definitely," Zardari replied to a question. "We do not hope to even get to that position when we have to use (nuclear weapons)," he said. "I can get my parliament to agree to it right away. Can you (India) get your parliament to agree to it?" he asked. "I do not feel threatened by India and India should not feel threatened from us," he underlined. India and Pakistan have already signed an agreement on not attacking each other's nuclear facilities. Immediately after detonating nuclear devices in 1998, New Delhi declared a moratorium on further tests and offered a no first use arrangement. Pakistan had not reciprocated the Indian offer. Zardari's remarks appeared to signal a radical departure from Pakistan's nuclear doctrine. Pakistan has always argued that since its deterrence is very small it was not in a position to accept no first use of nuclear weapons doctrine. Indicating a positive agenda for a lasting rapprochement with India, Zardari said that he had approached parliament for the constitution of a caucus that could go into all the problems between India and Pakistan, including the Kashmir issue. The caucus would especially look at resolving the Kashmir dispute and the possibility of developing trade between the two countries, he said. "Let the people of India and let the people of Pakistan decide. Let's take the challenge to the people of India and Pakistan," Zardari said when asked about his ideas for solution to the decades-old Kashmir dispute. "Let them (Pakistanis) force me and let the Indian people force the Indian politicians to come together to find a peaceful solution in which we can really say we have done justice to Kashmir," he said. Zardari also struck an upbeat note about scaling up economic engagement with India that could revolve around free trade and greater economic integration in the framework of the South Asia Association for Regional Cooperation (SAARC). "There was a little bit of an Indian in every Pakistani and a little bit of a Pakistani in every Indian. And therefore the two countries should join together and help each other," he said. "I am for improving relations with India and improving trade," said Zardari, who has been advocating greater economic ties between the two countries since he became president nearly three months ago. "Yes, let's open each other's border and trade. We can both mutually benefit from trade. If you can trade with China, why not with Pakistan?" Zardari said. He hoped that India and Pakistan would become an economically unified zone like the EU. However, he refused to comment on the possibility of a single currency for the two countries. In a reply to a separate question on the economic situation in Pakistan, he said he did not believe in aid but trade for pushing economic recovery in his country as he was looking at the market of over a billion people in India and China. In yet another significant statement that has the potential to transform relations between the two neighbours, Zardari made a pitch for special e-card that could enable freer travel between the two countries for their citizens. "I am hopeful we will find methodology. We could have special card of some sort - an e-card which you show at the border and just walk in," he said when asked about liberalization of the onerous visa regime that exists between the two countries. Zardari said Pakistan was ready to carry joint operations with India, against the Somali pirates. He said Pakistan would fully cooperate with India, if India seeks Pakistan's support to curb the menace of Somali Pirates in the Indian Ocean. It is pertinent to note that India has been accorded the responsibility to eliminate the threat of Somali pirates from the platform of United Nations Organization. Samajwadi Party leader Amar Singh, renowned actor Sanjay Dutt, parliamentarian, ambassadors of different countries, leaders of business community, academicians and senior journalists were present on the occasion and put questions to President Zardari. Highlights Zardari backs more trade and economic engagement between India and Pakistan. "Let's open each other's border and trade." Has approached Parliament for constitution of a caucus that could go into all the problems with India, including Kashmir. Supports visa-free travel, proposes e-card. "We could have special card - an e-card which you show at border and get in." There is a little bit of an Indian in every Pakistani and a little bit of a Pakistani in every Indian. And therefore the two countries should join together and help each other. We shall take Pak-India ties to a new level. I do not feel threatened by India and India should not feel threatened from us. Today we have a parliament which is already pre-agreed upon a friendly relationship with India. Backs opening of the movie industry between two countries.
