KABUL (Agencies) - Pakistan Wednesday described as "disappointing" India's claims that official agencies in Islamabad were involved in the Mumbai attacks, saying they would not help build cooperation amidst finger-pointing. Foreign Minister Shah Mahmood Qureshi who is accompanying President Asif Ali Zardari to Afghanistan told reporters here at a Press conference that "Indian politicians have fallen prey to Mumbai [attacks]". He said Pakistan condemns the Mumbai attacks, regardless of who were the perpetrators and has offered joint investigations. "If we have to get to the bottom, we have to have cooperate and have to keep the communication channels open," Qureshi said. He said Pakistan has offered India to cooperate with India to bring the perpetrators to justice. "How do you cooperate when you start pointing fingers? For God's sake, if you want cooperation, then stop the accusations." He said he was disappointed by Indian Prime Minister's statement as he considered him to be a visionary and a seasoned politician. He said Mumbai incident should not be allowed to overshadow relations between the two countries. "Indians are not being far-sighted," he said and added that earlier Indian authorities clearly stated that neither the government of Pakistan nor was the state of Pakistan was involved. Qureshi when asked about the shifting of troops from Pakistan's western to eastern borders, said: "Pakistan does not want war" and added that it desires a cooperative environment and good neighbourly relations. "However if war is imposed, then Pakistan will fight back with full conviction ... no sane person wants war." The Foreign Minister said western border was very important for Pakistan. "If we want stability in Pakistan the western border is very important," he said and added: "We want to remain engaged in western border." He said operations in FATA were very targeted and there was no question of moving away from the western border. Qureshi said Pakistan wants to honour all its commitments as it is a responsible country and understands its national obligations. He also ruled out any military-political disconnect, saying it is an old story. "We have excellent working relationship and speak with one voice." Foreign Minister Qureshi supported setting up of several working groups to identify feasible projects for consideration by the Regional Conference on Afghanistan to be held in Islamabad in April this year. He said this would help make the conference more result-oriented. He acknowledged European Union's offer to host an expert-level meeting in Brussels for coordination of those who wanted to contribute to the regional economic development. He said Pakistan intends to support all international initiatives in Afghanistan. Foreign Minister described the joint declaration signed by Pakistan and Afghanistan as a historic and watershed document that would take the bilateral relationship to new heights. He said Pakistan wished to build a level of confidence and trust with Afghanistan, adding there was a sea change in relationship between the two countries since President Asif Ali Zardari sworn in. He said ever since assumption of power by the democratic government in Pakistan, the two countries had moved from suspicions and finger-pointing to a relationship based on trust and confidence. He said Pakistan was in favour of a peaceful and stable Afghanistan, and wanted the relations to grow over the period of time. He termed the mini jirga in Islamabad a success and said it was a useful instrument of dialogue and should be fully used to engage parties at all levels. He said President Zardari and President Karzai during their talks strongly condemned the Gaza attacks, and mentioned that Pakistan had already demanded an end to Israeli aggression and asked the UN representatives to work towards an early ceasefire. Foreign Minister also expressed the confidence that the understanding between Pakistan and Afghanistan on the need to eliminate narcotics trafficking would help tackle the problem. He said narco-money was contributing to extremism and terrorism and stressed the need to break this nexus. To another question, Qureshi said Inter Services Intelligence (ISI) is an important national institution which made tremendous contribution in the war against terror and this role was being recognised the world over. He said, "The contribution of ISI should not be overlooked."
