Afghanistan's Foreign Minister Salahuddin Rabbani on Monday opened four-nation talks aimed at drafting a road map for eventual peace with the Taliban.
Representatives from Afghanistan, Pakistan, the United States and China gathered in Kabul to discuss how to get the Taliban to the negotiating table.
They were considering possible venues and dates for a meeting between the Afghan government and Taliban militants.
"We want all of the Taliban to join us at the table for peace talks," Rabbani said. "Any delay in coming to the table will put the Taliban in a corner."
If the Taliban refused to attend the talks, he said, they would prove that their aim is not peace.
"Although we are patient with the peace process, the people of Afghanistan will not accept and trust a prolonged peace process with no results," Rabbani said.
A joint statement was due to be released after the meeting.
