British Prime Minister David Cameron Monday hosted a trilateral summit with the leaders of Afghanistan and Pakistan to help bolster their strategic partnership. Both Afghan President Hamid Karzai and his Pakistani counterpart, Asif Ali Zardari, were accompanied by foreign ministers and other officials for the London meeting with Cameron, according to a report of the United Press International (UPI). The trilateral meeting took place as Karzai works to move the peace process with the Taliban in his country forward and secure further cooperation from his Pakistani neighbor. The Voice of America quoted a British statement that it expects the Afghans and Pakistanis to make further progress on the outlines of a strategic partnership accord discussed last September.
