David Cameron is to meet the Afghan and Pakistani presidents in the latest round of talks aimed at preventing a Taliban resurgence in Afghanistan when British troops leave next year.
The prime minister will dine with Hamid Karzai and Asif Ali Zardari at Chequers on Sunday night as part of his efforts to strengthen Afghanistan-Pakistan relations and promote regional peace and stability.
The meeting comes before in-depth discussions on Monday focusing on how the Pakistanis and international community can support the Afghan-led peace process.
Foreign ministers, army chiefs of staff, intelligence chiefs and the chairman of the Afghan High Peace Council are expected to attend the third trilateral session since last summer.
A Downing Street spokeswoman said: "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. We share the same vision for Afghanistan: a secure, stable and democratic country that never again becomes a haven for international terror.
"We are working together to achieve it and Afghanistan's neighbours have a vital role to play. It is vital not just for the future security of their citizens, but for their prosperity too."
