WASHINGTON-With the Taliban insurgency growing in Pakistan and Afghanistan, US President Barack Obama will host talks with President Asif Ali Zardari and his Afghan counterpart Hamid Karzai in this capital City early next month, The Washington Post reported on Wednesday. The meeting on May 6 and 7 will elevate to Summit level a trilateral exchange begun by the US administration with Foreign Ministers and senior aides of the two govts in late February. President Zardari and President Karzai will meet separately with the US leader and the three will also sit down together for discussions, the paper said, citing unnamed officials. The Obama administration, which is struggling to implement its new strategy for the region, considers cooperation between the two governments crucial to the success of its Afghanistan-Pakistan policy, the newspaper said. Washington believes that the Pak side of their shared border harbours a growing network of extremist groups, including al-Qaeda and the Taliban, providing sanctuary for fighters combating US and NATO forces in Afghanistan and launching terrorist attacks inside Pakistan itself. Obama has emphasised that the two countries should be considered in a single strategic framework. But administration officials, the Post says, have made clear that their deepest and most immediate concern is Pakistan, where the stability of the civilian govt and its ability to withstand the extremist onslaught is increasingly in doubt. Worries were heightened last week when President Asif Ali Zardari approved an agreement authorizing Shariat in the Swat Valley after the military action failed to rout Taliban fighters there. 'With no US military forces on the ground in Pakistan, the administration has fashioned a policy based on diplomatic backing for the civilian govt, close monitoring and support of the Pak military, aerial-drone-launched missile attacks on terrorism targets, and vastly increased economic assistance focused on the Western Federally Administered Tribal Areas, the Post dispatch said. At a Pakistan donors conference in Tokyo on Friday, the administration pledged $1 billion in economic aid in anticipation that Congress will approve a $7.5b, five-year package of assistance alongwith $3b in military equipment and training. A bill authorizing the aid has already been introduced in the House, although with conditions that the administration and the Pakistanis find too restrictive. The administration is facing the beginning of the spring fighting season against Taliban forces in Afghanistan, as well as Presidential elections there in August, it pointed out. Obama has already authorised the deployment of 21,000 additional US troops and hundreds of new diplomatic and other civilian officials.
