Spokesperson Suhail Shaheen said Taliban will seek a "new chapter" of tolerance.
The Taliban want to take control of Afghanistan "in the next few days", a spokesman for the group told the BBC Sunday, as their fighters encircled the capital.
"In next few days, we want a peaceful transfer," Suhail Shaheen, based in Qatar as part of the group's negotiating team, told the BBC.
Suhail Shaheen laid out the policies of the Taliban ahead of an expected power transfer that would re-install the hardline Islamic group two decades after US-led forces toppled them in the wake of the September 11, 2001 attacks.
"We want an inclusive Islamic government... that means all Afghans will be part of that government," Suhail Shaheen said.
"We will see that in the future as the peaceful transfer is taking place."
He also said foreign embassies and workers would not be targeted by the group's fighters and they should remain in the country.
"There will be no risk to diplomats, NGOs, to anyone. All should continue their work as they were continuing in the past. They won't harm them, they should remain."
Rebuffing fears the country would be plunged back to the dark days of the group's ultra-conservative version of Islamic law, Suhail Shaheen said the Taliban will instead seek a "new chapter" of tolerance.
"We want to work with any Afghan, we want to open a new chapter of peace, tolerance, peaceful coexistence and national unity for the country and for the people of Afghanistan," he said.
But many officials, soldiers and police have surrendered or abandoned their posts, fearing reprisals against anyone suspected of working with the Western-backed government or Western forces.
Suhail Shaheen said that would not happen. "We reassure that there is no revenge on anyone. Any case will be investigated."
The Doha-based spokesman said the group would also review its relationship with the United States.
"Our relationship was in the past," he said. "In future, if it will touch our agenda no more, it will be a new chapter of cooperation."
