ISLAMABAD - The new US special envoy on Pakistan and Afghanistan, Richard Holbrooke, arrived here Monday on his maiden visit to the region to devise a comprehensive plan aimed at curbing the Al-Qaeda and Taliban led insurgency in Afghanistan and Pakistani tribal areas. The US envoy will also visit Afghanistan and India after concluding his four-day visit to Pakistan. "I am here to listen and learn the ground realities of this critically important country," a US embassy statement quoted him as saying on his arrival in Pakistani capital. The US looks forward to reviewing its policies and renewing its commitment and friendship with the people of Pakistan, according to statement. During his visit, the US special envoy will call on President Asif Ali Zardari, Prime Minister Gilani and Foreign Minister Shah Mahmood Qureshi and all these meetings will take place today (Tuesday). In addition to that Holbrooke will also meet top military leadership including Pakistan Army Chief General Ashfaq Parvez Kayani. His visit is also likely to take him to Lahore and tribal areas. On his arrival, Foreign Ministry spokesman, Abdul Basit said, "Pakistan looks forward to the beginning of a process of constructive engagement with the United States, especially in the wake of assumption of office by President Obama and his team." He said the talks with special US envoy would hopefully give him the perspective that Pakistan had on issues confronting the country, Afghanistan and the whole region. Another official desiring not to be named said Pakistani officials would explain their position on Afghanistan, Taliban insurgency in tribal areas and also on Indo-Pak relations marred by tensions in the wake of Mumbai attacks. He said Pakistani leadership would also urge the new US envoy to increase assistance for Pakistan, both military and non-military, keeping in view the colossal losses caused by the ongoing war on terror. "One important issue is that of US drone attacks on tribal areas and Pakistani leaders will ask for halt to them as the civilian casualties caused by them have increased the anti-US sentiments thus also harming the efforts aimed at curbing militancy," the official said. Monitoring Desk adds: American State Department says that U.S. special representative for Pakistan and Afghanistan will speak with senior Pakistani authorities this week about the release of a Pakistani scientist Dr Abdul Qadeer. The State Department also said Monday that the U.S. ambassador to Pakistan spoke with foreign ministry officials Sunday and was assured that Abdul Qadeer Khan will not be a future proliferation risk. Spokesman Robert Wood told reporters that the U.S. "remains very disappointed" by Khan's release. Wood says the United States will closely follow Khan's case. He said Secretary of State Hillary Clinton has not raised the matter with her Pakistani counterpart.
