Karzai's decision to suspend those talks came a day after NATO-led troops transferred security responsibility to Afghan forces.
The Afghan government suspended the talks "in view of the contradiction between acts and the statements made by the United States of America in regard to the Peace Process," it said in a statement.
Hopes revived for captured soldier
Bergdahl was captured after he finished his guard shift at a combat outpost in Afghanistan's Paktika province, in the southeastern section of the county. Since his capture, four videos of the Idaho native have been released.
The last video was sent in February 2011, and it's unclear where Bergdahl is being held now. He was a private at the time.
The army has been giving him promotions that would have come to him had his Army career gone as planned. If he returns home safely, the Army will give him all the back pay that he has earned while in captivity.
The military told CNN it had no reason to believe Bergdahl was dead.
Bergdahl's family received a letter from the captive soldier recently. His father mentioned receiving the letter in an e-mail exchange with Dwight Murphy, the spokesman for the local POW/MIA group in Boise Valley, Idaho.
"We have received a letter from Bowe through the Red Cross!" the father says in the exchange. "He was scripted and redacted but he was no doubt alive and his faculties fully functioning as of two months ago."
He did not say when he got the letter, but Murphy copied and pasted the exchange with the father on his Facebook page after receiving his permission to do so.
The father's letter goes on say, "They are being very careful with him. He is still highly valued at high levels.
"Guantanamo, drones and politics in Afghanistan, Pakistan and Washington are still the big issues."
His father has rarely spoken to the media.
In his exchange with Murphy, he said he believed "we are getting closer to a resolution." But, he added, there seems to be a disagreement among the Taliban about the direction forward.
"It appears at least several parties want to arbitrate captive SGT Bowe, several others ... want to keep fighting until every single Westerner is out," the father said.
