President Obama is making a surprise visit to Afghanistan on the first anniversary of the death of the al-Qaeda leader Osama bin Laden. He has signed a 10-year strategic partnership agreement with the Afghan leader Hamid Karzai, setting out military and civil relations between their two countries after the conclusion of Nato's mission in Afghanistan in 2014. From Washington, Paul Adams.
就在基地组织头目本拉登被毙一周年之际,奥巴马总统将突防阿富汗。他与阿富汗领导人卡尔扎伊签署了一份十年战略伙伴关系协议,规定了2014年北约结束阿富汗军事任务后两国的军事和民事关系。Paul Adams在华盛顿报道。
Air Force One, the jumbo jet carrying President Obama, landed at the Bagram airbase north of Kabul. The president then flew onto the Afghan capital by helicopter. He'll only be on the ground for a few hours, but the strategic partnership he and President Karzai have just signed is the product of months of difficult negotiations. Only when differences over night raids by special forces and the handling of prisoners were ironed out did the agreement finally fall into place. It's a first symbolic step towards setting out a long-term relationship designed to reassure the people of Afghanistan that they are not about to be abandoned when Nato ends its operations there in 18 months' time.
