Afghan President Ashraf Ghani has offered recognition of the Taliban as a legitimate political group as part of a proposed political process that he said could lead to talks aimed at ending more than 16 years of war.
The offer, made at the start of an international conference aimed at creating a platform for peace talks, adds to a series of signals from both the Western-backed government and the Taliban suggesting a greater willingness to consider dialogue.
Mr Ghani proposed a ceasefire and a release of prisoners as part of a range of options including new elections, involving the militants, and a constitutional review.
It is part of a pact with the Taliban to end a conflict that last year alone killed or wounded more than 10,000 Afghan civilians.
"We are making this offer without preconditions in order to lead to a peace agreement," Mr Ghani said in opening remarks to the conference attended by officials from around 25 countries involved in the so-called Kabul Process.
"The Taliban are expected to give input to the peace-making process, the goal of which is to draw the Taliban, as an organisation, to peace talks," he said, adding that he would not "pre-judge" any group seeking peace.
The comments, a month after a suicide attack in central Kabul killed around 100 people, represented a change in tone for Mr Ghani, who has regularly called the Taliban "terrorists" and "rebels".
Despite this, he has also offered previously to talk with parts of the movement that accepted peace.
The United Nations mission in Afghanistan welcomed the offer and said it "strongly supports the vision for peace through intra-Afghan dialogue".
The Taliban, fighting to restore Islamic rule after their 2001 defeat by US-led troops, have offered to begin talks with the United States but have so far refused direct talks with the Afghan government.
It was unclear whether they would be prepared to shift their stance, despite growing international pressure.
However Mr Ghani, who recently helped launch the latest stage in a major regional gas pipeline from Turkmenistan, said the momentum for peace was building from neighbouring countries that increasingly saw the necessity of a stable Afghanistan.
"The Taliban show awareness of these contextual shifts and seem to be engaged in a debate on the implications of acts of violence for their future," he said.
