British Prime Minister David Cameron will hold key talks with the leaders of Afghanistan and Pakistan aimed at improving cooperation between both countries, support the Afghan peace and reconciliation process and promote regional peace and stability. The trilateral summit, will include Afghan and Pakistani army and intelligence chiefs for the first time. Cameron will host a dinner with Karzai and Zardari at his official country residence Chequers north of London on Sunday evening. He will then hold the in-depth talks with both presidents and their key officials on Monday. “This trilateral process sends a very clear message to the Taliban: now is the time for everyone to participate in a peaceful political process in Afghanistan,” Downing Street said in a statement. “As the prime minister has set out previously, a stable Afghanistan is not just in the interests of Afghans, but also in the interests of their neighbours and the UK,” it said. NATO troops are scheduled to withdraw from Afghanistan by the end of 2014. In a process initiated by Cameron last year, Afghan President Hamid Karzai and Pakistani President Asif Ali Zardari have agreed to work together on a framework of co-operation following the international troops’ departure next year. The first two rounds of the trilateral talks were held in Kabul and New York last year.
