Afghan and Pakistani leaders are expected to discuss security in Afghanistan after the NATO troop pullout and efforts to negotiate with the Taliban when they meet in Turkey today.
Turkish President Abdullah Gul hosted Afghan President Hamid Karzai and Pakistani Prime Minister Nawaz Sharif over dinner late yesterday, on the eve of the summit opening.
It is the eighth in Turkey since a regular consultation mechanism was established in 2007 to encourage the neighbours to cooperate in the fight against extremist groups.
The talks will primarily focus on ways to restore peace and promote reconciliation in Afghanistan, a senior Pakistani official told AFP.
Sharif emphasised ahead of the summit the need for peace and stability in its neighbour as US-led troops prepare to withdraw.
"Peace and stability in Afghanistan has a direct bearing on Pakistan. We support a sovereign, independent and united Afghanistan. The drawdown of NATO/ISAF by the end of the year as part of the security transition, will be a watershed event," he told Turkey's Hurriyet Daily News.
"We hope the drawdown will be managed while preserving regional peace and security. Pakistan also wishes Afghanistan every success in drawing a path for sustainable peace and development," he said.
Karzai has long accused Pakistan of sheltering Taliban militants waging the insurgency against his government.
Last month, Kabul reignited traditional cross-border suspicions by suggesting that Islamabad's spy agency was behind an attack on a Lebanese restaurant in the Afghan capital in which 21 people, including 13 foreigners, were killed.
Taliban insurgents claimed responsibility for the January 17 suicide assault, which was the deadliest attack on foreign civilians since the Taliban were ousted in 2001.
Intelligence officials and high-level military officials from the two countries were expected to hold closed-door talks on the sidelines of the Ankara meeting, the theme of which is "sustainable peace in the heart of Asia".
Karzai, who is due to step down after presidential elections on April 5, is pushing for Pakistan to help start peace talks with the Taliban.
He has demanded progress on talks before Afghanistan signs a security deal with the US that would allow about 10,000 troops to stay in the country after this year.
The supporters of the pact, known as the Bilateral Security Agreement, say it is crucial to Afghanistan's stability after the draw-down of NATO forces by December 31, 2014.
