UNITED NATIONS - Vowing to continue supporting Afghanistan's efforts to achieve peace and security, Pakistan has brought into sharp focus of the international community its the losses and sufferings from the decades of conflict and instability in the neighbouring country. "(N)o country or people have suffered more than Pakistan from the direct consequences" of the Afghan war, Ambassador Abdullah Hussain Haroon told the UN General Assembly on Monday. "We have endured political, security, social, economic and environmental consequences of the protracted war in Afghanistan and the presence of vast numbers of refugees in Pakistan ...", he said while participating in the assembly's annual debate on the situation in Afghanistan. Haroon said that an estimated 150 billion dollars had been spent in hosting Afghan refugees over the years which constituted a year of  Pakistan's gross Domestic Product (GDP). "This is our contribution and (the) one that has cost us dearly and brought us very close to financial difficulties that we are faced (with) today," he said. "The backlash has also been most severe in Pakistan," the ambassador went on to say. "As a result of our role in the counter-terrorism campaign, the security environment on our side has deteriorated sharply. Thousands of innocent civilians have fallen victim to terrorism in Pakistan, and sensitive to the sentiments of our people, the new democratic government is evolving national consensus to confront and defeat the terrorists". The ambassador said sustained engagement and commitment of the international community to the war-torn nation was critical for regional and international peace and security. "Our support for the international efforts in Afghanistan demands reciprocal cooperation based on goodwill, respect for each other's sovereignty and territorial integrity, and mutual commitment not to allow our respective territories to be used against each other," Ambassador Abdullah Hussain Haroon said. In this regard, he drew attention of the delegates to President Asif Ali Zardari's recent statement that Pakistan would not allow its territory and sovereignty to be violated. "We need to build peace in Afghanistan, region by region, using incentives and peace dividends, he said. "Genuine national reconciliation is also crucial for the success of the Afghan and international efforts to bring peace and stability in the country. Winning support of the peaceful majority is essential to isolate and break the insurgency". Ambassador Haroon said that terrorism posed a common threat to both Afghanistan and Pakistan.  Pakistan, he said, had deployed 110,000 military personnel on its side of the border with Afghanistan and had lost more soldiers than the combined losses of the international security forces in Afghanistan.  Much of the region's success against Al-Qaeda and Taliban had been achieved with Pakistan's support and cooperation. Pakistan's support for the international efforts in Afghanistan demanded reciprocal cooperation, Haroon said. Violations of territorial sovereignty undermined joint efforts and actually served to "empower the forces against which we are fighting together".   In addition to cooperation on security issues, he said, the two countries had begun an invigorated plan to diversify and strengthen their relationship while promoting mutual trust and good will.  The two sides had agreed to engage on multiple tracks, including political, military, intelligence and economic cooperation. The lack of security remained a major problem and concern and the control of the international border between Afghanistan and Pakistan was a joint responsibility, the ambassador said.  Pakistan was determined to carry out its part and was committed to working with the Afghanistan and international forces. The Tripartite Commission continued to play an important role and should be fully used. Much more needed to be done on counter-narcotics, and short-term measures needed to be complemented by comprehensive, durable and long-term solutions based on alternative livelihoods.  He said the United Nations had a central role in the international efforts and UNAMA had a well-defined mandate.  A huge development effort was required to turn around the situation in Afghanistan.  Only through mutual cooperation and support could peace, stability and prosperity be achieved in Afghanistan and the region.
