Karzai told CNN's "Larry King Live" in an interview to be broadcast Monday that "unofficial" discussions with Taliban representatives are continuing.
"We have been talking to the Taliban as countryman to countryman," said Karzai. "Not as a regular official contact with the Taliban with a fixed address, but rather unofficial personal contacts have been going on for quite some time."
On Sunday, the Afghan government named former President Burhanuddin Rabbani as chief of a new peace council tasked with talking to insurgent groups.
The 70-member panel was created by Karzai to guide peace negotiations.
