ISLAMABAD " Pakistan on Thursday rejected as "speculative" the international criticism including that from NATO over the introduction of Islamic judicial system in Swat. "There are some reactions including from NATO, these are mostly speculative," said the Foreign Office Spokesperson Abdul Basit while addressing his weekly press briefing. He was asked for his reaction to criticism from NATO and some Western nations over what is being dubbed as fresh 'peace deal' with militants in Swat valley. Basit said Pakistan would use all possible means to achieve the objectives of peace and security in the region. He said, "Understandings regarding Nizam-e-Adl (Justice System) are sequentially linked to the restoration of peace and tranquillity, therefore speculations in the matter will not be helpful." To another question on the status of Swat deal, he said that Prime Minister Yousuf Raza Gilani had already said that it was part of Pakistan's three-pronged strategy, namely dialogue, deterrence and development to counter terrorism. In reply to a question on US drone attacks on the country's tribal regions, Basit said that those were counter-productive. However, he hoped that there would be a positive change as a result of the US policy review. Earlier, in his opening statement, the spokesperson said the three-day visit of President Asif Ali Zardari to China, starting on February 20 (today), would promote economic and trade relations between the two countries. He said President Zardari's visit was part of his quarterly visit to China to explore economic cooperation. He said the visit was aimed at exploring avenues for cooperation with China in the fields of energy and agriculture resources. To a question on latest development on the front of Mumbai attacks, he said Pakistan was waiting for Indian reply to the questions raised out of the preliminary investigation into the terrorist act on the basis of the information that was provided by India. "Pakistan always said its disputes and conflicts with India shall be resolved through dialogue and negotiations," he said. He said Pakistan was of the view that there was no room for war to resolve the conflicts in the region. He said that Foreign Minister Shah Mahmood Qureshi would leave for Washington soon to participate in the review meeting on anti-terrorism policy. He also hoped that there would be a positive change in the review of policy towards the issue of drone attacks. Answering a query on formal request for the extradition of Ajmal Kasab involved allegedly in Mumbai carnage, the spokesperson once again denied any such request by Pakistan.
