"We're ready to restart talks about peace with Pakistan again and forget bitter experiences of the past and start a new chapter," he said at the start of an international conference in Kabul.
Ghani proposed starting talks without preconditions, opening the constitution for review and even helping the Taliban open a political office, though it's unclear if it would be located in Kabul or in another country. He also offered to reintegrate and help remove sanctions against Taliban members who engage in peace talks, denounce violence, recognize the Afghan government and respect the rule of law.
But the proposal in its current form could have trouble getting off the ground.
A stipulation that women be part of the negotiations could prove to be a poison pill for a militant group whose fundamentalist interpretation of Islam has women treated as second-class citizens.
The Taliban has yet to respond through its official spokesman.
'Struggling to survive'
The announcement could signify a growing rift between Kabul and Washington. Just last month, US President Donald Trump said the White House was not ready to talk with the Taliban, citing the terror group's continued use of violence.
The Taliban has been waging a bitter fight in Afghanistan with the ultimate goal of ruling the country and imposing its strict interpretation of Islamic law. The group controlled Afghanistan until 2001, when it was overthrown by the US-led coalition that invaded the country following the 9/11 attacks.
Just hours after Ghani's proposal, the Taliban was accused of kidnapping 19 people, including five police officers, in the province of Kandahar, the region's police spokesperson Zia Durani told CNN. The group did not immediately claim responsibility for the abduction.
